– NCS2K-MF-DEG-5 – provides full mesh patch between 5 degrees, using 5 MPO connectors (two strands on each MPO are patched to two strands on every other MPO)
– NCS2K-MF-UPG-4 – provides full mesh patch between a set of 4 degrees using 4 MPO connectors to another set of 4 degrees using 4 MPO connectors
– NCS2K-MF-16AD-CFS – provides 1 to 16 channel colorless omni-directional add/drop from 1 COM/RX strand to 16 drop strands and 16 add strands to 1 COM/TX strand
– NCS2K-MF-4X4-COFS – provides 4 to 4 channel colorless omni-directional add/drop from 4 COM/RX strands to 4 drop strands and 4 add strands to 4 COM/TX strands (the 4x COM/TX and 4x COM/RX are combined into an MPO port)
The key point here are that the -DEG-5 and -UPG-4 passive modules are used for building a full mesh patch panel between degrees which is what the question is looking for… whereas the -CFS and -COFS modules are used for add/drop functionality, unrelated to the question.
