TranSwitch funds Optix's PHY designs

Optix Networks Inc., a semiconductor startup, said a minority investment by TranSwitch Corp. involves a strategic alliance that includes product planning, joint engineering, and an OEM agreement that will see TranSwitch sell Optix products under the TranSwitch label.

Optix intends to optimize physical-layer functions in OC-192 and OC-768 networks, spanning duties between the switching fabric and the serializer/deserializer. Haim Moshe, chief technology officer at Optix, said the center of design differentiation at the company resides in forward error correction and framer functions. Its FEC designs will include both standard Reed-Solomon coding blocks, as well as proprietary coding algorithms. The company's Ultra-FEC family, slated for a late 2002 debut, could redefine FEC designs in high-speed markets, the company said.

In framer fields, Optix plans to be the first to implement digital wrappers to full International Telecommunication Union G.709 standards, said Shailendra Kumar, the company's vice president of business development. And though Optix's center of gravity resides at 40Gbps, the company said it is cognizant of market realities. "We leverage the 40Gb work to have a full 10Gb suite, including macros for packet-over-Sonet, 10Gb Ethernet, time-division multiplexing, generic-framing protocol, and resilient packet ring," Kumar said. "In some senses, it's been a boon for us to have a 40Gb market delay, since we get to expand our 10Gb product offering."

In all cases, the company will concentrate on integrated frame and Sonet overhead processing that can be accomplished in mainstream 0.135m CMOS. While the company does not rule out looking at III-V materials when necessary, "our roots remain strictly in silicon," Kumar said.
