Abstract
An automatic power reduction (APR) system for an optical network module, including: a multi-fiber interface including a plurality of ports adapted to be coupled to one or more multi-fiber connectors; a card processor operable to detect a loss of signal on an input port of the plurality of ports and comparing the power of an associated output port to an activation threshold received by the card processor; and a module processor operable to, in the event that the loss of signal is detected on the input port and the power of the output port exceeds the activation threshold, trigger the optical network module to execute an APR routine and attenuate spectrum associated with an affected port using a wavelength selective switch coupled to the plurality of ports.

An automatic power reduction (APR) system for an optical network module, comprising:
- a multi-fiber interface comprising one or more ports adapted to be coupled to one or more multi-fiber connectors;
- a card processor operable to detect a loss of signal on an input port of the one or more ports and comparing the power of an associated output port to an activation threshold received by the card processor;
- and
- a module processor operable to, in the event that the loss of signal is detected on the input port and the power of the output port exceeds the activation threshold, trigger the optical network module to execute an APR routine and attenuate spectrum associated with an affected port using a wavelength selective switch coupled to the one or more ports.
An automatic power reduction (APR) method for an optical network module, comprising:
- in a multi-fiber interface comprising one or more ports adapted to be coupled to one or more multi-fiber connectors, at a card processor, detecting a loss of signal on an input port of the one or more ports and comparing the power of an associated output port to an activation threshold received by the card processor;
- and
- in the event that the loss of signal is detected on the input port and the power of the output port exceeds the activation threshold, at a module processor, triggering the optical network module to execute an APR routine and attenuate spectrum associated with an affected port using a wavelength selective switch coupled to the one or more ports.
A computer-readable medium storing computer-executable instructions configured to cause the following steps to occur:
- in a multi-fiber interface comprising one or more ports adapted to be coupled to one or more multi-fiber connectors, at a card processor, detect a loss of signal on an input port of the one or more ports and compare the power of an associated output port to an activation threshold received by the card processor;
- and
- in the event that the loss of signal is detected on the input port and the power of the output port exceeds the activation threshold, at a module processor, trigger the optical network module to execute an automatic power reduction (APR) routine and attenuate spectrum associated with an affected port using a wavelength selective switch coupled to the one or more ports.
