Provider of Internet infrastructure semiconductor devices, PMC-Sierra has rolled out a new Forward Error Correction (FEC) technology for 100 and 40 G Optical Transport Network (OTN) installations.
The Swizzle FEC offers 10 dB or more Net Effective Coding Gain (NECG) for Optical Transport Network overhead configurations with more than 6.7%.
The Swizzle FEC platform produces a high NECG of 9.45 dB to allow 35% more optical reach compared to other FEC technologies that are typically based on the 7% overhead prescribed in the ITU G.709 standard. The increased demand for bandwidth from enterprise data, video and mobile data services is propelling network operators to deploy 100 and 40 Gb/s OTN links in the regional and metro networks. The data rates need complex modulation schemes and increased symbol rates that maximize sensitivity to optical impairments in fiber-optic networking equipment. To compensate the impairments, the Swizzle FEC corrects a maximum of four times of errors and increases the optical spans across the current fiber infrastructure.
The Director of Marketing of Communication Products Division at PMC-Sierra, Babak Samimi stated that the company’s Swizzle FEC technology would help drive the economic feasibility of 100 and 40 G OTN installations. Samimi added that by minimizing the number of optical regenerators needed and increasing the optical reach, operators can economically shift to scalable OTN transport infrastructures.
