Telecommunications – PMC-Sierra Offers Forward Error Correction Technology for 40G and 100G OTN Deployments

To improve the quality of video streaming, PMC-Sierra, Inc., the premier Internet infrastructure semiconductor solution provider has launched its new Forward Error Correction (FEC) technology for high performance, cost-effective 40G and 100G Optical Transport Network (OTN) deployments.


According to a press release, PMC-Sierra’s (News - Alert) Swizzle FEC offers the Net Effective Coding Gain (NECG) of 9.45dB, enabling 35 percent greater optical reach than other competing hard FEC technologies based on the seven percent overhead specified in the ITU G.709 standard.

Swizzle FEC compensates for these impairments, correcting up to four times as many errors as competitive solutions, maximizing optical spans over the existing fiber infrastructure. It delivers 9.45dB of Net Effective Coding Gain 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 10dB or higher NECG for OTN overhead configurations of greater than the 6.7 percent.

The explosion of bandwidth demands from mobile data, video and enterprise data services is driving network operators towards deployment of 40Gb/s and 100Gb/s OTN links in their metro and regional networks.  

Babak Samimi, director of marketing of PMC-Sierra’s communication products division said that capital spending remains a barrier to entry for mass deployment of 40G and 100G OTN technology and the company’s Swizzle FEC technology will be a significant contributor in driving the economic viability of 40G and 100G OTN deployments.

In other company news, TMCnet reported that PMC-Sierra, has announced the release of Adaptec (News - Alert) by PMC family of Series 6 RAID controllers designed for high I/O transaction and high bandwidth processing applications.
