Metro 100G Gets Some Buzz
The claim is that there's a market for 100Gbit/s parts that are cheaper and less power-hungry than the coherent design in that framework. Along the same lines, ADVA Optical Networking announced a direct-detection (that is, non-coherent) 100Gbit/s technology a few weeks ago.
MultiPhy's MP1100Q, announced Monday, is a demultiplexer chip for the receive side of a 100Gbit/s link. It's based on MultiPhy's own digital signal processor (DSP) and an analog-to-digital converter (ADC). MultiPhy claims it can offer lower power and costs partly because its ADC runs at 28 billion samples per second, rather than the 56 billion being used for coherent 100Gbit/s.
Why this matters
It's starting to look like this metro 100Gbit/s idea is for real. Finisar Corp. (Nasdaq: FNSR) and Oclaro Inc. (Nasdaq: OCLR) both tell Light Reading the idea has potential.
"We definitely have customers that are interested in other technologies," says Per Hanson, vice president of product marketing with Oclaro. "The typical example is data centers across the metro, or if you have high-capacity routers you need to connect across the metro."
There's no standard at work here, so it's possible that incompatible metro 100Gbit/s technologies will emerge. Whether that's a problem, as it was for the 40Gbit/s long-haul market, is yet to be seen.
