Generic Requirements for Multi-
The optical interface must meet the FT-1435-CORE requirement in
Fiber Optical Connectors . The module must pass the wiggle test defined by IEC 62150-3.
CS Connector
You can use patch cables with CS connectors to connect two supported transceivers of the same type-
for example, 2x100G-LR4 to 2x100G-LR4 or 2x100G-CWDM4 to 2x100G-CWDM4. CS connectors are
compact connectors that are designed for next generation QSFP-DD transceivers. The CS connector
provides easy backward compatibility with QSFP28 and QSFP56 transceivers.
LC Duplex Connectors
You can use patch cables with LC duplex connectors to connect two supported transceivers of the same
type—for example, 40GBASE-LR4-to-40GBASE-LR4, or 100GBASE-LR4-to 100GBASE-LR4. A patch
cable is one fiber pair with two LC duplex connectors at opposite ends. LC duplex connectors are also
used with 12-fiber ribbon breakout cables.
Figure 20 on page 50 shows how to install an LC duplex connector in a transceiver.
