Intranodal ROADM fiber management apparatuses, systems, and methods
First Claim
1. A N-degree system, comprising:
- a line degree subsystem, the line degree subsystem including N line degree modules;
a plurality of transceivers;
an add/drop subsystem interposed between the line degree subsystem and the plurality of transceivers, the add/drop subsystem including a plurality of subsystem modules; and
an expansion module system interposed between at least one of the N line degree modules and at least one of the plurality of subsystem modules,wherein N is an integer greater than zero,wherein at least one of the expansion module or at least one N degree line module comprises (a) a first wavelength selective switch and (b) one of a second wavelength selective switch or a splitter, andin a case where the at least one N line degree module comprises the first wavelength selective switch and the one of the second wavelength selective switch or the splitter, the first wavelength selective switch selects from among wavelengths received from at least one of the subsystem modules and outputs at least one selected wavelength to an egress path, and the one of the second wavelength selective switch or the splitter receives at least one wavelength from an ingress path and outputs the at least one wavelength to the at least subsystem module, andin a case where the expansion module comprises the first wavelength selective switch and the one of the second wavelength selective switch or the splitter, the first wavelength selective switch selects from among wavelengths received from at least one of the subsystem modules and outputs the selected wavelengths to at least one of the N line degree modules, and the one of the second wavelength selective switch or the splitter receives at least one wavelength from at least one of the N line degree modules and outputs the at least one wavelength to at least one of the subsystem modules.

Abstract
An intranodal reconfigurable optical add/drop multiplexer (ROADM) fiber management apparatus, and a system employing the apparatus. The apparatus comprises a plurality of ingress optical ports, a plurality of egress optical ports, and a plurality of optical interconnections interposed between ones of the plurality of ingress optical ports and ones of the plurality of egress optical ports. Each of the plurality of ingress optical ports corresponds to one of the plurality of egress optical ports. Each one of the plurality of ingress optical ports is optically coupled by way of the optical interconnections to at least one of the plurality of egress optical ports. Each one of the plurality of egress optical ports is optically coupled by way of the optical interconnections to at least one of the plurality of ingress optical ports.
