VSC6134
10 Gb/s Transport Processor with Enhanced FEC
GENERAL DESCRIPTION:
The VSC6134 is a bi-directional transport
processor providing Forward Error
Correction (FEC), SONET/SDH section and
line processing, 10 Gb/s Ethernet performance
monitoring and G.709 Digital Wrapper
termination and generation for fiber optic
transmission lines operating at approximately 10 Gb/s. As
recommended by ITU-T G.975 and G.709, VSC6134 provides FEC
based on a block oriented Reed-Solomon code RS(255,239) in
addition to an optional proprietary FEC code that provides
increased gain with the same overhead as RS(255,239). The
required error correction symbols are transferred out of band
increasing the transmission data rate by 7.1%.
The VSC6134 FEC device provides superior error correction of
arbitrary data streams of approximately 10 Gb/s for applications
in data and telecom networks. It is especially suitable for
OC192c/STM- 64 SONET/SDH and 10Gbps Ethernet applications,
as it supports monitoring and termination of section and line
overhead as well as RMON.
As recommended by ITU-T G.709, in standard FEC mode, error
coding is performed using a 16X interleaved block oriented
Reed-Solomon RS (255,239) coder, resulting in a maximum
correctable burst error length of 1024 bits. In enhanced FEC
mode, a different code with iterative decoding is used to provide
increased code gain. Due to the out of band transmission of the
parity bits and framing/overhead information, the transmission
rate is increased by a factor of 1.07 in both standard and
enhanced FEC mode resulting in a 10.7 Gb/s transmission rate.
