Connectors and Cabling
Connectors: 12-fiber female MPO/MTP connector (-SR4), dual SC/PC connector (-LR4 and -FR).
Note: Only connections with patch cords with PC or UPC connectors are supported. Patch cords with APC
connectors are not supported. All cables and cable assemblies used must be compliant with the standards
connectors are not supported. All cables and cable assemblies used must be compliant with the standards
specified in the standards section.
