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. The flexible design of the VSC9271 enables the device to be used in a variety of applications with and without FEC.The VSC9271 conforms to the ITU-T G.975 standard for transparent FEC. The FEC is supported by the Optical Channel (OCh) which has its own set of performance monitoring and maintenance features defined by the ITU-T G.709 standard. These features are independent of the client signal carried, simplifying the operation of an optical network supporting various client signals. The VSC9271 offers bidirectional adaptation and regeneration capabilities for OCh signals.

An integrated multi-rate bidirectional performance monitor (PM) supports a variety of client signals. For SONET/SDH, the device monitors and modifies the transport (section and line) overhead of STS-192/STM-64, STS-48/STM-16, STS-12/STM-4, and STS 3/STM-1 client signals, which allows for support of Operations, Administration, Management, and Provisioning (OAM&P) functions. In addition to SONET/SDH, the VSC9271 supports the monitoring of GbE and FC signals, as well as a bypass mode to support any other data format.
