Kim Roberts, senior director coherent systems at Ciena, adds some mathematical rigour with his explanation of Shannon's bound, from a workshop he gave at the recent Layer123's Terabit Optical and Data Networking conference held in Cannes.

Part 1: NGPON2

The next-generation passive optical network (PON) will mark a departure from existing PON technologies. Some operators want systems based on the emerging standard for deployment by 2015. 


“One of the goals in FSAN is to converge on one solution that can serve all the markets"

Derek Nesset, co-chair of FSAN's NGPON task group 

 

The Full Service Access Network (FSAN) industry group is close to finalising the next optical access technology that will follow on from 10 Gigabit GPON.

The deal, valued at US $177M, will result in Opnext's shareholders owning 42% of the combined company. The merger of the fifth and sixth largest optical component players will create a company with annual revenues of $800M, second only to Finisar. The deal is expected to be completed in the next 3-6 months.

The emergence of a second de-facto 100 Gigabit standard, a complement to 100 Gigabit coherent, gained credence with 4x28 Gigabit-per-second (Gbps) direct detect announcements from Finisar and Oclaro and likely backing from system vendor, ECI Telecom.

 

 

"We believe that in some cases operators will prefer to go with this technology instead of coherent"

Shai Stein, CTO, ECI Telecom
