Wednesday, August 15, 2012 at 7:23PM AppliedMicro has announced the first CMOS merchant multiplexer chip for 100Gbps coherent optical transmission. The S28032 device supports dual polarisation, quadrature phase-shift keying (DP-QPSK) and has a power consumption of 4W, half that of current multiplexer chip designs implemented in BiCMOS.

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"

Friday, October 15, 2010 at 10:06AM In the second and final part, Rafik Ward, vice president of marketing at Finisar, discusses Google’s call for a new 100 Gig interface, the ECOC show, and what Finisar has learnt from running a corporate blog.
"Feedback we are getting from customers is that the current 100 Gig LR4 modules are too expensive"

Wednesday, January 6, 2010 at 10:27AM Transceiver feature - 3rd and final part
Optical equipment and transceiver makers have much in common. Both must contend with the challenge of yearly network traffic growth and both are addressing the issue similarly: using faster interfaces, reducing power consumption and making designs more compact and flexible.
Yet if equipment makers and transceiver vendors share common technical goals, the market challenges they face differ. For optical transceiver vendors, the challenges are particularly complex.
