Optical Signal-to-Noise Ratio Specications
From Release 2.6, L100 Blade introduces an enhanced Opcal Signal-to-Noise Rao (OSNR) performance feature.
This feature provides improved levels of opcal power for both exible grid and xed 50-GHz applicaons with
the following benets:
■ Reachability is enhanced especially for signals greater than standard 50 GHz.
■ Signal quality is improved. The signal quality improves the Pre-FEC BER and provides enhanced network
resiliency to network transients.
The OSNR enhancement seng is at the NE level and is mainly for a new build network. System alarms against
any span level interface if the OSNR seng is dierent between spans (adjacent nodes). By default, OSNR
enhancement seng is disabled. In some cases, changing the OSNR seng on a running system may impact the
signal trac.
Note: Fujitsu recommends any change to the OSNR seng on a running system be performed during a
maintenance window.
Note: OSNR seng must be enabled in L100 Blade to support interoperability with L130 Blade.
