Abstract
A reconfigurable optical add/drop multiplexer (ROADM) complex in an optical network may include one or more core ROADM devices, each including multiple input/output port pairs configured for respective wavelengths or wavelength bands to be coupled to a fiber distribution panel (FDP) over fiber. The FDP may include multiple FDP connectors to receive optical signals from the core ROADM device(s) and may extract and route optical signals having a single wavelength to respective transponder connectors of the FDP for coupling to a transponder. Multiple expansion options may be enabled at the FDP. For example, according to one option, a single expansion connector may be enabled for coupling to an expansion device to provide additional drop port capacity. In another example, multiple expansion connectors may be enabled for coupling to respective expansion devices.
