GENERAL DESCRIPTION

The VSC9271 is a multi-rate bidirectional Forward Error Correction Device (FEC) with Digital Wrapper and performance monitoring. The VSC9271 employs a bidirectional architecture that can be used in both transceiver (adaptation) and regenerator modes. In both cases performance monitoring at the client signal level may be performed for STS-192/STM-64, STS-48/STM-16, STS-12/STM-4, STS-3/STM-1, Gigabit Ethernet (GbE), and Fibre Channel (FC) signals.
