FIBER-MANAGEMENT SOLUTION FOR AN OPTICAL-NETWORK NODE
First Claim
1. An apparatus comprising:
- a first set of optical ports;
a second set of optical ports;
a third set of optical ports;
a fourth set of optical ports; and
a plurality of optical waveguides, each disposed to optically connect a respective pair of the optical ports, the plurality of optical waveguides disposed to optically connect;
each optical port of the first set to each optical port of the second set;
each optical port of the first set to another optical port of the first set;
each optical port of the third set to each optical port of the fourth set; and
each optical port of the third set to two other optical ports of the third set.

Abstract
We disclose a modular fiber-interconnect device that can be used in a ROADM to optically interconnect wavelength-selective switches and optical add/drop blocks thereof. An example module of the modular fiber-interconnect device has seventeen optical ports, each implemented using an MPO connector of the same type. The number of (nominally identical) modules in the modular fiber-interconnect device depends on the degree N of the ROADM and can vary, e.g., from two for N=4 to fourteen or more for N≥20. A proper set of duplex optical connections within the ROADM can be created in a relatively straightforward manner, e.g., by running MPO cables of the same type from the wavelength-selective switches and the optical add/drop blocks of the ROADM to appropriate optical ports of the various modules of the modular fiber-interconnect device.
