Fiber and Connector Losses in Raman Link Configuration
This document provides important guidelines to be followed when
configuring a Raman link regardless of whether you are configuring
the Raman link using the Raman installation wizard or the
Cisco Transport Planner (CTP) XML file. Ensuring the desired gain
and gain flatness is critical to the success of the configuration.
The Raman installation wizard automatically addresses any deviation
in connector and fiber splice loss values by displaying warning
messages appropriately, provided they are within the limits
detailed in Table 1. However,
configuration of the Raman link using the CTP XML file is based on
the algorithms within CTP. Any deviation in the connector and fiber
splice losses values leads to unpredictable behavior of the entire
system, in terms of Raman tilt and optical signal-to-noise ratio
(OSNR). For these reasons, configuring the Raman link using the
Raman installation wizard is preferred than configuring using the
CTP XML file.
