"40Gbps has even less value in the metro than in the core"
Andrew Schmitt, Infonetics Research
Friday, January 6, 2012 at 7:46AM The next-generation CFP modules - the CFP2 and CFP4 - promise to double and double again the number of 100 Gigabit-per-second (Gbps) optical module interfaces on a blade.

Tuesday, December 6, 2011 at 9:52AM Oclaro has detailed its 100 Gigabit coherent optical module that will be available from the second quarter of 2012. The MI 8000XM, a 5x7-inch 100 Gigabit-per-second (Gbps) transponder, uses NTT Electronics' (NEL) analogue-to-digital converter/ digital signal processor (DSP) ASIC at the receiver that compensates for transmission impairments.
“The world is moving to coherent, there is no question about that”
Per Hansen, Oclaro
Tuesday, October 25, 2011 at 10:18AM Gazettabyte spoke with BT, Level 3 Communications and Verizon about their 100 Gigabit optical transmission plans and the challenges they see regarding the technology.
Briefing: 100 Gigabit
Part 1: Operators
Operators will use 100 Gigabit-per-second (Gbps) coherent technology for their next-generation core networks. For metro, operators favour coherent and have differing views regarding the alternative, 100Gbps direct-detection schemes. All the operators agree that the 100Gbps interfaces - line-side and client-side - must become cheaper before 100Gbps technology is more widely deployed.
"It is clear that you absolutely need 100 Gig in large parts of the network"
Steve Gringeri, Verizon
100G serial interface, 100Gbps, BT, CFP, CFP2, Level 3, Verizon, service providers in Feature Print Article Tuesday, October 11, 2011 at 10:34AM Gazettabyte has published a Position Paper on the coming 100 Gigabit metro opportunity. (Click here to download a copy.) There has been several announcements in recent weeks from system and component vendors addressing 100 Gigabit metro networks.
The 19-page report looks at the status of the 100 Gigabit market, the drivers for 100 Gigabit deployment, the technology options and their merits. The paper then states how 100 Gigabit technologies such as direct-detection point-to-point, direct-detection WDM and coherent will fare in the metro.
Wednesday, September 28, 2011 at 5:20PM Transmode has detailed its 100 Gigabit metro strategy based on a stackable rack, a concept borrowed from the datacom world.
The Swedish system vendor has adopted coherent detection technology for 100 Gigabit-per-second (Gbps) optical transmission, unlike other recent metro announcements from ADVA Optical Networking and MultiPhy based on 100Gbps direct-detection.
"Metro is a little bit diverse. You see different requirements that you have to adapt to."
Monday, September 19, 2011 at 6:56PM MultiPhy has detailed its 100 Gigabit direct-detection receiver IC for use in a pluggable CFP optical module addressing the metro market.
The MP1100Q chip is being aimed at two cost-conscious metro networking requirements: 100 Gigabit point-to-point links and dense wavelength-division multiplexing (DWDM) metro networks.
