Connectors and Cabling
The SFP optical transceiver module on the Cisco 76-ES+T-40G line card requires dual or single LC/PC
connectors. 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 specified below:
• GR-20-CORE: Generic Requirements for Optical Fiber and Optical Fiber Cable
• GR-326-CORE: Generic Requirements for Singlemode Optical Connectors and Jumper Assemblies
• GR-1435-CORE: Generic Requirements for Multi-Fiber Optical Connectors
For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable or
two simplex LC-type cables, one for transmit (TX) and one for receive (RX). See Figure 2-30.
