Abstract
A management system for an optical line system includes one or more processors and memory storing instructions that, when executed, cause the one or more processors to receive State of Polarization (SOP) measurements from one or more optical components in the optical line system, wherein the SOP measurements are taken while traffic-bearing channels are operating, and monitor health of one or more fibers based on the SOP measurements. The health can include detection and/or localization of SOP transients.
Claims20
A management system for an optical line system, the management system comprising:
- one or more processors and memory storing instructions that, when executed, cause the one or more processors to
- receive State of Polarization (SOP) measurements from one or more optical components in the optical line system, wherein the SOP measurements are taken while traffic-bearing channels are operating,
- monitor health of one or more fibers based on the SOP measurements, and
- provide the health of the one or more fibers to enable one or more of 1) configuring a transmitter for use on the one or more fibers, 2) selecting a type of transmitter for use on the one or more fibers, 3) selecting a type of receiver for use on the one or more fibers, 4) configuring a receiver for use on the one or more fibers, and 5) determining whether to restore a failed connection from another fiber to the one or more fibers.
A method comprising steps of:
- receiving State of Polarization (SOP) measurements from one or more optical components in an optical line system, wherein the SOP measurements are taken while traffic-bearing channels are operating, and
- monitoring health of one or more fibers based on the SOP measurements;
- and
- providing the health of the one or more fibers for enabling one or more of 1) configuring a transmitter for use on the one or more fibers, 2) selecting a type of transmitter for use on the one or more fibers, 3) selecting a type of receiver for use on the one or more fibers, 4) configuring a receiver for use on the one or more fibers, and 5) determining whether to restore a failed connection from another fiber to on the one or more fibers.
A non-transitory computer-readable medium comprising instructions that, when executed, cause on or more processors to perform steps of:
- receiving State of Polarization (SOP) measurements from one or more optical components in an optical line system, wherein the SOP measurements are taken while traffic-bearing channels are operating,
- monitoring health of one or more fibers based on the SOP measurements, and
- providing the health of the one or more fibers for enabling one or more of 1) configuring a transmitter for use on the one or more fibers, 2) selecting a type of transmitter for use on the one or more fibers, 3) selecting a type of receiver for use on the one or more fibers, 4) configuring a receiver for use on the one or more fibers, and 5) determining whether to restore a failed connection from another fiber to the one or more fibers.
