QSFP Transceiver Module BlueOptics QSFP-40GE-LR4-BO Fiber Optic LC Interface

The BlueOptics QSFP-40GE-LR4-BO is a 40G fiber optic transceiver module with a QSFP interface and LC duplex connectors. Designed for single-mode fiber, it supports high-speed optical transmission for network equipment that accepts QSFP 40GBASE-LR4 modules. The module is compact and lightweight (approximately 20 g) with an aluminium housing, suitable for installation in data center switches, routers and storage systems that support LR4 optics.

Advantages

This QSFP transceiver follows MSA-compliant form factor and LC connector standards to ensure interoperability with a wide range of networking hardware. It supports 40GBASE-LR4 optical links over single-mode fiber, providing long-reach connectivity. The module includes digital diagnostics (DDM/DOM) capability for remote monitoring of supply voltage, laser bias current, transmit power, receive power and temperature when the host hardware supports these functions. The compact aluminium design and low weight simplify handling and installation in dense rack environments.

How to use

Install the QSFP-40GE-LR4-BO into a compatible QSFP port on your network device following the device manufacturer's hot-plug instructions. Use LC duplex single-mode patch cords or a suitable breakout assembly for interconnection. Ensure the host equipment supports 40GBASE-LR4 optics and, if you intend to use monitoring features, that the device firmware exposes DDM/DOM parameters. Verify link status and settings in the switch or router management interface after insertion.

Recommendations

For reliable long-reach performance, use low-loss single-mode fiber and high-quality LC connectors. Confirm compatibility with your network hardware before deployment and enable digital diagnostics in the host system to monitor optical parameters and support remote troubleshooting.
