Programmable Wavelength-Selective Splitter

A method performed by a remote node of a communication network, the method comprising:

• receiving, from a central control node, a first optical signal comprising configuration information for a programmable wavelength-selective splitter (PWSS) of the remote node;
• and
• based on the configuration information, configuring the PWSS to direct one or more wavelengths of an incoming wavelength-division multiplexed (WDM) optical signal towards corresponding one or more of a plurality of ports of the PWSS,
• wherein the configuration information comprises one or more of the following:
• the identifier of the PWSS;
• an identifier of at least one of the plurality of ports;
• and an identifier of at least one of the one or more wavelengths.

A method performed by a central control node of a communication network, the method comprising:

• receiving one or more of the following information related to a programmable wavelength-selective splitter (PWSS) of a remote node of the communication network:
• an identifier of the PWSS, a serial number of the PWSS, a part number of the PWSS, a number of ports for the PWSS, and a total port capacity for the PWSS;
• and
• subsequently transmitting, to the remote node, a first optical signal comprising configuration information for configuring the PWSS to direct one or more wavelengths of an incoming wavelength-division multiplexed (WDM) optical signal towards a corresponding one or more of a plurality of ports of the PWSS.
