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, August 14, 2012 at 9:51AM Cortina Systems has announced its latest electronic dispersion compensation (EDC) chip. The CS4342 is a compact device that supports eight duplex 10 Gigabit-per-second (Gbps) links.
"Some customers are doing 2,000 signals at 10 Gig across the backplane"
Scott Feller, Cortina
Monday, July 30, 2012 at 5:31PM The Full Service Access Network (FSAN) group has chosen wavelength division multiplexing (WDM) to complement PON's traditional time-sharing scheme for the NG-PON2 next-generation standard.
"The technology choice allows us to have a single platform supporting both business and residential services"
Vincent O'Byrne, Verizon
Sunday, July 29, 2012 at 4:31PM Heavy Reading has published a report Photonic Integration, Super Channels & the March to Terabit Networks. In this 60-second interview, Sterling Perrin, senior analyst at the market research company, talks about the report's findings and the technology's importance for telecom and datacom.
"PICs will be an important part of an ensemble cast, but will not have the starring role. Some may dismiss PICs for this reason, but that would be a mistake – we still need them."

Thursday, July 19, 2012 at 2:55PM The view that consolidation in the optical networking industry is needed is not new. For a decade, ever since the end of the optical boom in 2001, consolidation has been called for and has been expected. And while the many optical startups funded then have long exited or been acquired, the optical industry continues to support numerous optical networking and component generalist and specialists.
Given the state of the telecom market, is a more fundamental industry restructuring finally on its way?
"The business model of the communication sector needs to change, and change in a relatively short order"

The OTN transport and switching market is forecast to grow at a 17% compound annual growth rate (CAGR) from 2011 to 2016, outpacing the 5.5% CAGR of the optical equipment market (WDM, SONET/SDH). So claims a recent study on the OTN equipment marketplace by Infonetics Research.

Friday, July 6, 2012 at 11:38AM Ten Gigabit-based parallel optics is set to dominate the marketplace for several years to come. So claims datacom module specialist, Avago Technologies.
"One customer told us it has to keep the interface speed below 20Gbps due to the cost of the SerDes"
Sharon Hall, Avago
"People are underestimating what is going to be involved in doing 25 Gigabit [channels]," says Sharon Hall, product line manager for embedded optics at Avago Technologies. "Ten Gigabit is going to last quite a bit longer because of the price point it can provide."
