NOTE
Works with 400G ZR optical modules.
1. When the transmission distance ranges from 40 km to 80 km and the insertion loss of
the optical link is less than 22 dB, the optical amplier needs to be congured only at the
transmit end.
2. When the transmission distance ranges from 80 km to 120 km:
1. When the insertion loss of an optical link is less than or equal to 24 dB, an optical
amplier needs to be congured only at the transmit end.
2. When the insertion loss of an optical link is greater than 24 dB but less than or equal to
28 dB, optical
ampliers must be congured at both the transmit and receive ends, and the
receive optical power threshold of the QSFP-DD optical module must be manually
modied.
3. If the insertion loss of an optical link is greater than 28 dB, the link needs to be
optimized to reduce the insertion loss to a value less than 28 dB.
Note: The optical amplier module works at the physical layer. If the corresponding
physical port is steady on, it indicates that the optical amplier module works normally and
no LOS alarm is reported. If the corresponding physical port is o, it indicates that the
optical
amplier module does not work normally or a LOS alarm is reported. If the status
of an amplier module port is up, the amplier module board is working properly and no
LOS alarm is reported. If the status of an amplier module port is down, the amplier
module board is not working properly or a LOS alarm is reported.
