VSC9271
10GB/s Multi-Rate Bi-directional FEC Device with Digital Wrapper and Performance Monitor
B E N E F I T S :
ꢀForward Error Correction techniques conform to industry standards
ꢀTransparent error detection and correction for any client signal
regardless of protocol or rate up to 10.3125Gb/s
ꢀBi-directional architecture enables independent FEC encode and
decode operation
ꢀExtensive Performance Monitoring and Regeneration Capabilities
for SONET/SDH signals, GbE, and Fiber Channel
ꢀRegenerator mode allows the device to be used as an FEC link
regenerator (decode, then encode) for repeater applications
