Integrated band splitter for scaling dual-band ROADM

Abstract:

Systems and methods for integrated band splitter for scaling a dual band Reconfigurable Optical Add/Drop Multiplexer (ROADM). A degree in a ROADM includes ROADM components including a line port and a plurality of connection ports; channel multiplexer/demultiplexer components including degree ports and local add/drop ports; and one or more band splitters in between the ROADM components and the channel multiplexer/demultiplexer components. The band splitter can be configured to split/combine C-band spectrum and L-band spectrum. The band splitter can be a passive fiber device.
