Network transceiver module ALCATEL QSFP-40G-LR QSFP+ 40 Gbit/s fiber optic

ALCATEL QSFP-40G-LR is a QSFP+ fiber optic transceiver module designed for 40 Gbit/s links over single-mode fiber at 1310 nm. The module provides a compact, hot-pluggable interface for switches and routers and is intended for high-capacity optical connections in data center aggregation and long-reach network uplinks. Typical reach is 10 km.

Advantages

The QSFP+ 40 Gbit/s form factor delivers four-lane high-density connectivity in a single pluggable module, reducing port space and simplifying cabling. Compatibility with QSFP+ ports ensures straightforward integration into existing network equipment. Support for single-mode fiber at 1310 nm and a typical reach of 10 km enables reliable medium-distance optical links for aggregation and interconnect applications.

How to use

Insert the QSFP-40G-LR module into a compatible QSFP+ port on a switch or router while the device is powered off or per the host equipment hot-swap procedure. Connect single-mode fiber optic cabling terminated with the appropriate connectors to the module. Configure the host interface for 40 Gbit/s operation as required by the network device. Monitor link status and diagnostics through the host equipment management interface.

Recommendations

Use single-mode fiber rated for 1310 nm and ensure fiber connectors and patch cords meet equipment specifications. Verify compatibility with the host switch or router QSFP+ port and follow manufacturer guidelines for handling transceivers to avoid contamination or electrostatic damage.
