QSFP+ Transceiver Module BlueOptics QSFP+40-LR4-BO 40000 Mbit/s

The BlueOptics QSFP+40-LR4-BO is a QSFP+ fiber optic transceiver module engineered for 40 Gbit/s links over single‑mode fiber. It implements a 40GBASE‑LR4 physical interface with LC duplex connectivity, supports transmission distances up to 10,000 m and is supplied in a compact silver housing weighing approximately 20 g. The module follows MSA‑compatible QSFP+ form‑factor conventions to ensure interoperability with hardware that accepts 40GBASE‑LR4 QSFP+ transceivers.

Advantages

This transceiver provides high‑speed 40 Gbit/s data transfer with long‑reach capability suitable for data center interconnects and campus backbone links. The LC duplex connector and single‑mode design reduce susceptibility to electromagnetic interference and enable simultaneous transmit and receive channels. The module is manufactured to common MSA specifications and is compatible with devices that support QSFP+ 40GBASE‑LR4 optics.

How to use

Install the QSFP+ transceiver into a compatible QSFP+ port on a switch, router or other network device following the host vendor's hot‑swap instructions. Connect single‑mode LC duplex patch cords to the module's LC receptacles, ensuring correct transmit/receive orientation. Verify link status on the host device and, if available, enable or read the Digital Diagnostics Monitoring (DDM/DOM) interface to monitor power, temperature and other operating parameters. Ensure fiber connectors and patch cords are clean and that the host firmware supports 40GBASE‑LR4 QSFP+ optics.

Recommendations

Use single‑mode fiber and LC duplex patch cords rated for 40G applications, keep connector endfaces clean, and confirm host compatibility and firmware settings before deployment. For monitoring and troubleshooting, enable DDM/DOM on compatible equipment to view real‑time diagnostic parameters.
