Abstract
A Reconfigurable Optical Add/Drop Multiplexer (ROADM) includes degree components where there are one or more Media Channels (MCs) configured thereon; multiplexer and demultiplexer components; and a controller configured to, responsive to a request for a loopback test on Network Media Channel (NMC) that is part of a configured Media Channel (MC), determine whether there are neighboring channels to the NMC, configure deadbands on optical spectrum based on the determining, cause configuration of a modem for the loopback test, and cause performance of the loopback test with the modem.
Claims20
A Reconfigurable Optical Add/Drop Multiplexer (ROADM) comprising:
- one or more of degree and add/drop components where there are one or more Media Channels (MCs) configured thereon;
- multiplexer and demultiplexer components;
- and
- a controller configured to
- responsive to a request for a loopback test on Network Media Channel (NMC) that is part of a configured Media Channel (MC), determine whether there are neighboring channels to the NMC,
- configure deadbands on optical spectrum based on the determining,
- cause configuration of a modem for the loopback test, and
- cause performance of the loopback test with the modem.
A method comprising steps of:
- responsive to a request for a loopback test on Network Media Channel (NMC) that is part of a configured Media Channel (MC), determining whether there are neighboring channels to the NMC;
- configuring deadbands on optical spectrum based on the determining;
- configuring a modem for the loopback test;
- and
- performing the loopback test with the modem.
