PMC-Sierra offers forward error correction for 40-Gbps 100-Gbps OTN

JANUARY 24, 2011 -- PMC-Sierra, Inc. (Nasdaq:PMCS) has unveiled a new forward error correction (FEC) technology for 40-Gbps and 100-Gbps Optical Transport Network (OTN) deployments.

JANUARY 24, 2011 -- PMC-Sierra, Inc. (Nasdaq:PMCS) has unveiled a new forward error correction (FEC) technology for 40-Gbps and 100-Gbps Optical Transport Network (OTN) deployments. PMC-Sierra’s Swizzle FEC is designed to deliver a net effective coding gain (NECG) of 9.45 dB. Swizzle will enable 35 percent greater optical reach than other competing hard FEC technologies based on the seven percent overhead specified in the ITU G.709 standard, PMC-Sierra asserts.

PMC-Sierra says its Swizzle FEC corrects up to four times as many errors as competitive approaches, maximizing optical spans over the existing fiber-optic network infrastructure.

“Capital spending remains a barrier to entry for mass deployment of 40G and 100G OTN technology,” said Babak Samimi, director of marketing of PMC-Sierra’s Communication Products Division. “Our Swizzle FEC technology will be a significant contributor in driving the economic viability of 40G and 100G OTN deployments. By maximizing optical reach and reducing the number of optical regenerators required, operators can cost-effectively transition to scalable OTN transport networks.”

PMC-Sierra’s Swizzle FEC delivers its 9.45 dB of NEFG within the lowest OTN overhead of 6.7 percent specified in the ITU G.709 standard, nearly reaching the theoretical maximum defined by the Shannon Limit. For long-haul deployments, the Swizzle FEC architecture delivers 10 dB or higher NECG for OTN overhead configurations of greater than the 6.7 percent.

The Swizzle FEC platform is available for demonstration and evaluation. PMC-Sierra has posted a Swizzle whitepaper on its site (registration required).
