Abstract

We present an open design of a filterless add/drop reconfigurable optical add/drop multiplexer module with a NETCONF northbound interface. Compared to commercial offerings, the device design is openly documented and available for detailed inspection. Performance is evaluated with up to seven adjacent high-speed 100 Gbps signals on a 50 GHz frequency grid.

Fig. 1. An example five-degree fully disaggregated ROADM node comprises seven independent modules: five line degree and two add/drop. In a fully disaggregated ROADM, each of the modules is independent. Our design simplifies the internals of the add/drop modules (orange inset, original WSS-based design shown), while the line degree modules (violet inset) remain unchanged.
