VSC9271
10GB/s Multi-Rate Bi-directional FEC Device with Digital Wrapper and Performance Monitor
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.
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.
