Saving 54 Watts (16%) on 2+0 XPIC
configuration.
2. Once any polarization is failed, the ODU’s
transmit power of the fault polarization (Local &
remote sites) will be muted automatically to
save the power consumption and avoid
interference
3. The system will try to recover the failed
polarization intermittently till the link recovery
