KDDI Deploying Teknovus TK3714 Turbo EPON ONU

Teknovus yesterday announced that its TK3714 Turbo EPON ONU will be deployed by KDDI in Japan. The TK3714 Turbo ONU can be configured to run in the standardized 1 Gbps mode of IEEE 802.3ah as well as an enhanced 2.5 Gbps mode. This is Teknovus' solution to match the GPON line rate.

One of the great features of the Teknovus chipset is the great amount of features and configuration options it provides, which may be handy for delivering advanced triple play services over an access network and managing a wide range of negotiated Service Level Agreements (SLAs) with different customers.

The big effort for 100 Gig Ethernet

Ever since the IEEE formally announced its commitment to a standard for 100 Gig Ethernet in its previous plenary at Dallas, there has been a remarkable news and discussion forum coverage on this topic. That is great marketing for 100 Gig Ethernet.

So what will be the key for this technology. I believe that the price/performance ratio is the key. It is interesting that 100 GigE does not mean 100 Gbps on one wavelength (or line). For now all it means is 100 Gbps available on an end-to-end Ethernet connection. This could be in combination of 10 channels of 10 Gbps. Optical fiber systems have supported such bandwidths for years, a typical fiber can carry 160 DWDM wavelengths at OC-192 (10 Gbps). But this is confined to backbone networks where hundreds of connections have been multiplexed. The challenge is in delivering this bandwidth to an adapter.

And even if this bandwidth is delivered, will the edge device (end system) the adapter is connected to be able to make use of such high bandwidths. This has already been a major hurdle for 10 Gig adapters.

So it will be interesting to see how this technology develops and matures.

MEF to discuss Ethernet Network-Netwrok Interface standard

LightReading reports that the Ethernet network-to-network interface (E-NNI), describing how networks will hand off Ethernet services to one another, will be among the topics pursued at the quarterly MEF meeting today.

The above standard is required so that carriers can easily interface with local area and access networks to deliver Ethernet frames and thereby services to customers. At present, there is no standard and therefore carriers are implementing custom solutions. Since there is fierce competition and lack of partnership between carriers, the issue of standardization may be more complex this time.

Custom Search on Ethernet

Last week Google introduced the Custom Search Engine (see related blog at Google). The idea is to allow users to create tightly coupled search engines related to their website or their blog.

I tried to implement one for this blog, and so here it is. And it works great actually. Try searching for the keyword 'ofc' (standing for the Optical Fiber Communication Conference) on Google. What you get is a wide assortment of links, as ofc can stand for just about anything. Now try it on the search in this blog. Bingo! All the results are related to the conference OFC. Now, you can further refine the results by intelligent topics, lets say by 'epon' (Click on link epon), which gives results relevant to epon for OFC. Similarly try the topic 'Carrier Ethernet'. Aint it great?

But sure there is scope for further improvement. Thats why Google allows volunteers to refine the search further. Interested in helping out? E-mail me, or leave a comment here, and I will invite you to modify the search engine.

Cisco's Ethernet Demarcation Box

LightReading has an interesting article today about Cisco releasing its first Ethernet demarcation box. A demarcation box includes Ethernet OAM to help carriers isolate faults in the network and determine if the problem is on the carrier or customer side of a connection. The demarcation box is intended to sit at the customer premises, or very close. This is an important step towards end-to-end Ethernet, because it helps carriers/service providers segment different portions of the network, and monitor them independently.

Matisse deploying Metro Ethernet with Optical Burst Switching

Today's Lightreading report discusses Matisse Networks gearing up for higher bandwidth Metro Ethernet. Matisse is a must-watch startup as it attempts to use "Optical Burst-Switching" technology which is widely research and understood but has not been commercially exploited and deployed.

Metro networks act as a bridge between backbone Internet networks (long-haul) and the access networks (such as DSL, Cable). As bandwidths in access increase and business enterprise traffic, the bandwidth in metro networks is expected to rapidly scale up.

With increased bandwidths, the cost of maintaining dedicated circuits using Dense Wavelength Division Multiplexed (DWDM) technology is not scalable. Reconfigurable Add-Drop Multiplexers (ROADMs) were built so that circuits can be reconfigured based on traffic demand. Matisse improves this furthur by using Optical Burst Switching (OBS) Technology. In OBS a train of packets known as a burst may be routed along a path on demand. This means no circuits need be pre-provisioned, and expensive circuit transponders need not be dedicated for every single communication path. This frees up expensive capital, simplifies network design, and enables the creation of the pure packet metro aggregation networks where bandwidth shifts in real-time to where it is needed in the network.

Matisse may have a bright future. Its founders have prior experience in establishing Amber Networks and selling it to Nokia for $421 million in 2001.

French Operator Illiad to spend 1 Billion Euros for Active Ethernet Deployment

French operator Iliad will deploy an "active Ethernet" strategy, where each household has a dedicated fiber connection, in its planned €1 billion (US$1.27 billion) fiber-to-the-home (FTTH) rollout. The news article on LightReading may be found here.
Iliad plans to hook up 4 million buildings and serve up to 10 million customers with its fiber rollout, starting in Paris in early 2007 and then spreading to other major French cities. It will also make the network available via the "open access" network model in which the FTTH network is made available to service providers on a competitive basis.

This seems to be a big win for Active Ethernet technology in Europe. Active Ethernet has been already deployed in a smaller scale in Amsterdam. North America and Korea+Japan are inclining towards Passive Optical Network (PON) technology for FTTH.

Juniper adds Ethernet Cars to E320 Edge router

Juniper announced a series of enhancements to its E320 Broadband Services Router designed to improve the router's IPTV capabilities. This includes adding 192 Gigabit Ethernet connections or 12 10-Gbit/s Ethernet links, managing up to 128,000 sessions in total. The E320 is deployed in more than 28 networks spanning four continents, including some of the world's largest IPTV and multiplay networks, Juniper says.

With these upgrades, the E320 can handle more traffic than Cisco 10000 series and the Redback SmartEdge 800, which handle 61,500 and 48,000 subscribers, according to the respective vendors. Juniper also claims it's got better Ethernet density than either of those.

Teknovus pushing hard in China

Teknovus, a vendor for EPON chipesets, today announced in a press release that their chips are being used by Chinese carriers in more than 20 cities and provinces, including Beijing, Shanghai, and Wuhan. According to Dr. Rex Naden, the CEO, a major selling factor for Teknovus in China has been its focus on delivering advanced services over EPON such as triple play services while meeting SLAs, managment of multiple traffic flows, and fulfilling strict Quality-of-Service requirements of Chinese carriers.

I am sure that China is a difficult but huge market to penetrate for EPON vendors, given that residential access traffic has been growing extremely fast in China. China has not yet adopted the IEEE 802.3ah standard. Moreover, companies which have an engineering base in China such as Immenstar, are likely to have a significant advantage for capturing the Chinese market with the advantage of having focusses local relationships.

The press release is available here.

Advanced services for the broadband access market

The growth of the broadband access market (that technologies such as 1/10 Gig Ethernet PON) cater to strong depends on the demand and popularity of advanced Internet services. The most popular and discussed service is TV/Video on Demand.

I am a huge fan of the on-Demand technology. My cable provider Comcast now provides select movies which can be ordered on demand. Some of them are free, but the free ones are usually the old classical movies. I guess Comcast would like to have every movie in its repository, but alas, the cable doesnt have enough bandwidth to meet the on demand request from every customer. So they hope that given the limited collection, only a small subset of its user base will request on-demand at a given time, by which they can afford to deliver this service over the limited bandwidth available.

More than video, I would like to have sports matches on demand. Tennis is my favorite sport. The US Open Series is on. However, ESPN telecasts only the one of the semi-finals and the finals live. However, all matches are recorded by television cameras. Wouldn't it be fun to have access to all matches live, so that I can watch whichever player I am a fan of, wherever he/she is playing.

So how about Video on demand technology. Ethernet PON technology is mature, although not yet vastly deployed. Video technology is mature. So the question is when can the two be integrated to make a commercially viable venture.

And we are not far away from this technology revolution. Today, Cisco bought Video-on-Demand server venfor Arroyo for $92 million. Last month, Motorola bought Arroyo's comeptitor for $186 million. The big players now see juice in this market. Which is great, because now the millions of dollars required for an intensive marketing effort to promote the technology and make it available to the masses so that it can be cheap and commerically viable is available.

And that is a huge developement for EPON chip vendors. For device technology matures very fast. But it takes services and software to catch up. Device vendors have to hinge their bets on this factor. So Cisco and Motorola taking keen interest in the video server market ought to be great news for Teknovus, PMC-Sierra, Immenstar and the others.

Lower prices boosting 10 Gig Ethernet according to HeavyReading

The 10-Gbit/s Ethernet market could be poised for a growth spurt, as prices are getting down to the critical level to kick up some serious demand, according to the latest Heavy Reading report, available at here. The LightReading report discussing the same is available here.

It notes that the chip technology prices are one-tenth what they were in the first generation of 10-Gbit/s Ethernet which has helped boost the volume of 10 Gig Ethernet sales. Modules are lowering systems prices by getting smaller. The industry started with the 300-pin multisource agreement (MSA) and has been moving through smaller module generations since -- to Xenpak, then X2, and eventually XFP. Vendors are already working on the next step beyond the XFP transceiver, called SFP+.

Prices for 10-Gbit/s ports have recently dropped to less than $10,000 per uplink -- which, with 48-port switches on the market, translates to less than $200 per user.

Bellsouth using Hettheras equipment for 45 Mbps Ethernet over Copper

Quake signal processing technology to reduce 10 Gig Ethernet cost

Quake Technologies today announced the availability of the QT2035S, an integrated physical layer IC for all 10 Gigabit Ethernet (10GE) applications. To quote Mitch Kahn, Quake's vice president of marketing:

Today, the wholesale cost for a typical XFP module for short-reach 10G Ethernet is approximately $350. Using Quake's new QT2035S and SFP+ technology, the cost of a module for this same reach can be reduced to below $100. At this new price point, 10G Ethernet becomes very compelling for a range of high-volume applications

PMC-Sierra posts weak projection on EPON growth

PMC-Sierra's stock was hit by 25% today, after it projected lesser growth in EPON revenues, one of the key technologies it had pinned its growth on. PMC-Sierra had bought Passave for $300 million last quarter. The EPON revenues in this quarter are $16 million, while the expected revenues in next quarter are $13 million.

According to a LightReading report available here, the problems seems to be from Japan, where NTT wants to use fewer Optical Line Terminals (OLTs). NTT has been deploying roughly one OLT per four subscribers but wants to use a one-to-eight ratio -- resulting in fewer OLTs in the short term. OLTs being the more expensive chipset compared to ONUs, yields better revenue and gross margins.

Passave's revenues have bounced around in the range of $10 million to $16 million per quarter for most of the past two years. So even though this past quarter was an all-time high, Passave doesn't seem to be showing the straight-line growth path investors were hoping for.

It seems that part of the problems in the slow growth of EPON is high competition (as many as three other startups: Teknovus, Immenstar, Centillium), and a very limited market in Korea and Japan. Because these chipsets are sold to equipment vendors and resellers, may lead to lesser gross margins.

Given that, the price of $300 million that PMC-Sierra paid seems to be sky high.

Yankee Group Research shows Ethernet growing rapidly in Asia Pacific

According to "Big Bandwidth, Low Prices: Asia's Speed Demons Review", published by the Yankee Group, several factors are driving the boom of the Asia-Pacific wide-area Ethernet market including surging bandwidth requirements, the ability to provision bandwidth on-demand and a gradual network migration. Asia-Pacific is the second largest market after Europe in terms of revenue from Ethernet services, totaling $676.5 million in 2005. Most service providers in Asia-Pacific offer their Ethernet services over an MPLS-based IP VPN network. Although Metro Ethernet is gaining momentum in the corporate networking arena, the capability to offer enhanced manageability and service performance remains critical for service providers to stand out and win enterprise business.

Ethernet Growth to drive 10 Gig optical industry

An interesting analysist report by Communications Industry Researchers (CIR), (news analysis available here)claims that manufacturers of optical modules based on semiconductor lasers and modulators should witness a boom in demand with rapid deployment of 10 Gigabit Ethernet from 2008 onwards. According to the forecasters at Communications Industry Researchers (CIR), the main reason behind the expected boom will be the deployment of products for use in short-range 10 Gb/s applications.

Immenstar introduces dual mode GPON/EPON

Immenstar, which recently came out of stealth mode to introduce EPON chips has now introduced a chipset that may operate in dual GPON/EPON mode. GPON and EPON are two different blends of the Passive Optical Network (PON). They differ in the technology used to encapsulate frames, while EPON uses the Ethernet, GPON uses the Generic Framing Procedure (GFP). While EPON has the advantages of blending in easily with the universal Ethernet ports (such as in LANs), GPON currently has a higher bit-rate in current operations and better operational control mechanisms.

I am not very sure of the motivation behind a dual mode GPON/EPON chipset, since the two different technologies have been growing in different markets. While the EPON has been strongly growing in the Asia-Pacific, the GPON has been growing in North America. It also seems unlikely that an operator would like to move to a GPON solution once he has chosen to go with EPON and vice-versa. May be the benefit it is in manufacturing ease, because a single product may now cater to both markets, and thus reduce the cumulative costs of operations, compared to having two differnt product lines. Any comments from readers would be great.

Chelsio raises $12 Million

Chelsio announced that it had raised $12 million Series D Venture Capital funding. Chelsio also announced that it had LSI Logic as an investor. The president and CEO of Chelsio Kianoosh Naghshineh mentioned that this funding with help Chelsio build its next generation Ethernet protocol offload engine, which will integrate NIC, TOE, iSCSI and RDMA functionality.

This round of funding should come as a huge relief to Chelsio, which has been struggling with increasing sales of its 10 Gig Ethernet and iSCSI technology. The big question is how much will the 10 Gig adapter market take off, given that current application is limited to cluster computing. One key area of growth may be in Storage Area Networks (SANs). SANs cuurently are limited to iSCSI technology which is limited to 1 Gig channels.

Teknous supporting TDM in GEPON

Teknovus is supporting TDM services in its latest GEPON chips which will have the ability to support traditional leased-line services. The two new chips are the TK3515 for ONU applications and the high-density TK3525 for OLT applications, thus providing efficient, end-to-end support for TDM-over-Ethernet services.

I believe that this step provides an easy migration path from leased-line services vailable currently to the next generation EPON world.

Immenstar in Ethernet PON Market

LightReading today has an interesting article about Immenstar, a startup, joining the EPON market. Immenstar has been operating in stealth mode for over two years. LightReading also mentions that Immenstar claims to have a multimillion dollar order due next month, possibly from UTStarComm which sells equipment to Softbank BB Corp for the deployment of Yahoo Broadband Service in Japan. UTStarComm previously used Passave (acquired by PMC-Sierra) chipsets but that didnt work very well as many of Passave chips had errors. The news article is available here.

The product portfolio of Immenstar is very interesting, it offers a Quad OLT chip with integrates 4 OLT ports and 4 Gigabit Ethernet ports with Non Blocking Switching. The company website mentions that the MuLan EPON Switch Chipset provides a carrier-class Ethernet ultrabroadband access solutions for network operators and service providers. It offers quality of service, fault tolerant operating system, hot swap capability, scalability, and high density system for the EPON access network.

It is interesting to see a startup in the EPON area, as there are already a bunch of companies competing for limited marketplace. EPON seems to be growing primarily in Japan and Korea while North America seems to be moving towards the GFP-PON market. And although different EPON chipset vendors promise to deliver quality of service, technologically there doesn't seem to be anything different that Immenstar has to offer compared to existing chipsets in the marketplace.

Furukawa announces Gigabit Interface Converter (GBIC) enabled EPON ONU

Furukawa has developed a EPON ONU with a GBIC (Gigabit Interface Converter) form-factor based on Teknovus’ TK3713 ONU chip. I believe that this is an important development for the EPON as it facilitates the expansion of the traditional Ethernet communications equipment manufacturers into the EPON market, and thus leverages one of the biggest advantages of the EPON -- the ubiquity of Ethernet. This should help penetrate the EPON technology in Fiber-to-the-Business (FTTB) because of easy integration of the local LAN with the EPON.

Any comments on potential customers of Furukawa?

Zhone Announces Active Ethernet Products

Zhone today announced its EtherActive Product to deliver high bandwidth Ethernet services over fiber in FTTP/FTTH markets. Zhone's EtherActive Optical Line Terminal (OLT) can support up to 10 subscribers per blade with 10/100/1000 Mbps service over either copper or single/dual mode fiber utilizing industry-standard EFM technology.

Active Ethernet has been chosen as an alternative high bandwidth solution to the Passive Optical Network (PON) in many parts of the world such as the city of Amsterdam. The main difference between the two is that while active ethernet is a point-to-point architecture, the PON is a tree-and-branch shared architecture while helps decrease fiber cost and share a channel/wavelength amongst multiple users.

BT keen on Nortel's Provider Backbone Transport

Nice article on LightReading about Nortel's Provider Backbone Transport (PBT). PBT is a management platform that takes out some of the management complexity of Ethernet for the delivery of point-to-point Ethernet services.

Nortel's approach is to simplify Ethernet by turning off features, such as the Spanning Tree protocol and MAC address flooding, and enabling network operators to manage their Ethernet service delivery by using a set of management tools. Nortel's claims that this approach gives the control and scaleability desired from Ethernet networks without relying on MPLS, thus making the solution cost effective.

Inifinera Joins Ethernet Alliance

Infinera is the first vendor completely focussing on optical systems and switches to join the Ethernet Alliance. Seems that this shall give the Ethernet Alliance added muscle as it pushes to 100 Gig Ethernet. Infinera has developed the first optical system offering capacity in 100 Gb/s increments, leveraging Infinera’s 100 Gb/s photonic integrated circuits (PICs). I

nfinera demonstrated 400 Gb/s PICs in 2005 and recently demonstrated the world's first 1.6 terabit per second (Tb/s) PIC. PIC technology promises to be a key enabler for scaling Ethernet into the Tb/s era. The steady advances of Infinera's PIC technology, combined with the rapid growth of bandwidth in the IP network, suggest that the move from 40 Gb/s to 100 Gb/s will take a fraction of the time of the move from 10 Gb/s to 40 Gb/s.
