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.

A nice informative discussion between Active and Passive Ethernet is available at:

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.

Broadcom Ships two billionth ethernet port

Broadcom has announced that it has shipped more than 2 billion Ethernet ports including 200 million Gigabit-over-copper PHY ports.

Broadcom shipped its first Ethernet port in 1995. In the Linley Group's "Networking Silicon Market Share 2005" report, Broadcom is ranked as the number one supplier of all Ethernet Integrated Circuits (ICs), including Gigabit Ethernet (GbE) and Fast Ethernet (FE) components and holds a 45.6% share of the market.

2 Billion. Amazing number. Demonstrates the ubiquity of Ethernet. What started as such a simple technology has surpassed all other technologies, and is now seen everywhere: notebooks, routers, switches, access points, ...

Aktino Gets Metro Ethernet Forum Certification

Aktino has been awarded the Metro Ethernet Form (MEF) 9 certification from Iometrix, the MEF authorized lab, for its AK4000 product family.

The AK4000 product family enables 10 to 25 Mbps business-class Ethernet services. Introduced in mid-2005, the AK4000 family is a cost-effective, operationally feasible business broadband solution to bridge the service gap between high-bandwidth, high-margin Ethernet over fiber services and low-bandwidth DS1 or Ethernet over DS1 HDSL-based solutions.

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. Please read more details on teh company press release which dates back to April 27, 2006.
