GEPON new subscribers overtakes DSL in Japan

An excellent article featuring the growth in the adoption of Ethernet PON technology (also called GEPON) in Japan came to my attention recently. It shows NTT achieving more subscribers to the GEPON FTTH technology than ADSL. NTT charges FTTH subscribers about 4000 yen or $40 per month. NTT is also planning to deploy video service over GE-PON using a different downstream wavelength.

Startups in race for 10 GbE over Copper

Lightreading has reported another starup - Aquantia joining the race to provide 10 GbE solutions of Copper wire. 10 GbE over Copper is being standardized at the IEEE 802.3an also called 10GBase-T, which is expected to be ratified by June next year. It provides for 10GbE over distances of 100 metres on Category 6 Copper wire. Proprietary solutions to 10GbE already exists in the market today - for example, one provided by Chelsio Communications, KeyEye Communications, and Quake Technologies.

Amsterdam going with active Ethernet for FTTH

Its interesting to see Amsterdam go with active Ethernet for this $35 million project which will connect 40,000 homes, as opposed to EPONs. The lightreading report mentions the decision being based on a report from Riverstone Networks, a pioneer for Metro Ethernet, which states that EPONs may provide 39Mbps per user as oppossed to Ethernet's 100Mbps.

While it is an interesting debate between Metro Ethernet and EPONs, I feel that EPONs cetainly have an edge in residential access networks, primarily because of low end equipment cost and zero maintainance. Moreover the above study is surely misleading. EPONs offer 1 Gbps connectivity which may be shared between multiple users. The peak bit rate is thus 1 Gbps. The average bit rate depends on the number of users you share with. If you have 32 users connected to an EPON, the average bit rate may be close to 39 Mbps. But if there is higher demand, you can share across lesser number of users.

Overall, it is nice to see some cities getting very serious with FTTH deployment.

Ethernet over MPLS specification

The MFA Forum announced today it is sending to final ballot a specification for Multi-Service Interworking-Ethernet over MPLS. The specification will enable service providers to introduce new Ethernet services in a heterogeneous network of ATM, Frame Relay, HDLC and PPP using MPLS as a communication broker. In addition, the specification will allow service providers to preserve critical ATM and Frame Relay infrastructure and ease migration to MPLS networks. Read more news by clicking on the title link.

Ethernet making big waves

10 years back, who would have thought that the simple, naive, trusted Ethernet would outplace every other competing technology including ATM. This simple protocol has evolved a lot over the years.

The objective of this forum is to collect news on "next generation" Ethernet products. Specifically Ethernet Passive Optical Networks (EPON) standardized in the IEEE 802.3ah, and 10 Gig Ethernet standardized in IEEE

We shall mainly be reporting on news from public sources like company websites, news forums, news websites, etc. so no insider info here :)
