Chapter 2 Cards Specifications

2.2.4 Optical Amplifiers

The OPT-AMP-L card implements the following optical safety functions:

•OSRI

•ALS

The OSRI function provides hardware and software capability for shutting down optical power or reducing it to a safe level, whereas the ALS function provides an APR safety mechanism for fiber cuts.

Table 2-26defines the standard and extended gain ranges for the OPT-AMP-L card.
