BlueOptics QSFP-40G-LR4 network transceiver module 40000 Mbit/s

The BlueOptics QSFP-40G-LR4 network transceiver module 40000 Mbit/s is a fiber optic module designed for high-speed, long-reach network links. With a QSFP interface and support for 40 Gbit/s throughput, the module is intended for use in switches, routers and servers where consolidated 40 Gigabit Ethernet or Infiniband connections are required over single-mode fiber.

Advantages

The transceiver combines a compact QSFP form factor with four-lane optical transmission to deliver up to 40 Gbit/s aggregate bandwidth while occupying a single port. It supports long-distance links over single-mode fiber, offering predictable signal integrity and low latency for backbone and data center interconnects. The module is hot-pluggable and interoperable with standard QSFP ports, simplifying installation and maintenance.

How to use

Install the BlueOptics QSFP-40G-LR4 into a compatible QSFP slot on the network device, ensuring the port and transceiver are rated for 40 Gbit/s operation. Connect appropriate single-mode fiber cables using the correct LC or MPO connector type as required by the LR4 implementation, and verify link status through the device management interface. Follow device vendor guidance to configure link aggregation, speed settings and any required transceiver diagnostics.

Recommendations

Verify compatibility with the host device and use single-mode fiber rated for long-reach LR4 transmission. Keep fiber connectors clean and avoid excessive bending of fiber cables. Monitor link status and transceiver diagnostics regularly to ensure consistent 40 Gbit/s performance.
