摘要： An apparatus is described. The apparatus comprises a downstream wavelength selective switch having an input port, an optical path operable to carry an optical signal, an optical source providing amplified spontaneous emission (ASE) light, an optical switch having a first input coupled to the optical path, a second input coupled to the optical source and receiving the ASE light, and an output coupled to the input port of the downstream wavelength selective switch. The optical switch couples either the first input or the second input to the output. Further included is a photodiode operable to monitor the optical signal, detect an optical loss of signal of the optical signal, and output a switch signal to the optical switch such that the optical switch couples the second input receiving the ASE light to the output whereby the ASE light is directed to the input port of the downstream wavelength selective switch.

摘要： An optical network is described that has a first ROADM node, a second ROADM node, and an optical transmission line establishing optical communication between the first ROADM node and the second ROADM node. The optical transmission line including an in-line amplifier node having a total input power and a total output power. The in-line amplifier node has a first monitoring tool configured to measure input optical power of the in-line amplifier node, and a second monitoring tool configured to measure output optical power of the in-line amplifier node. A software defined L0 network controller has circuitry configured to receive the optical power measured by the first and second monitoring tools from the in-line amplifier node, and to configure at least one of a gain and a gain tilt of the in-line amplifier node.

摘要： A multiplexer module and method are herein disclosed. The multiplexer module comprises a WSS configured to receive a plurality of first optical signals, selectively multiplex the first optical signals into a second optical signal, and output the second optical signal; an OPM operable to determine a power of one or more slice within a sample optical signal, the sample optical signal being selected from a group consisting of a particular optical signal of the first optical signals and a portion of the second optical signal including the particular optical signal; a processor; and a memory storing instructions that cause the processor to: validate the particular optical signal using the power of one or more slice within the sample optical signal; and if the particular optical signal is valid, cause the WSS to open a particular passband so as to multiplex the particular optical signal into the second optical signal.

摘要： Methods, systems, and optical power controllers are disclosed. Various problems caused by the use of a single L0 power controller in the prior art are addressed by using first and second L0 power controllers with the first L0 power controller managing first optical components with the optical network, and the second L0 power controller managing second optical components within the optical network.
