QSFP Transceiver Module BlueOptics QSFP-40G-PLR4-DL-BO 40 Mbit/s 1310 nm

The BlueOptics QSFP-40G-PLR4-DL-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s optical data transfer over single-mode fiber. It features an MPO/MTP connector and transmits and receives at 1310 nm, offering a compact, lightweight form factor (approx. 40 g) and a high mean time between failures (MTBF) of 1,000,000 hours for long-term operation in data center and high-performance networking environments.

Advantages

The module follows MSA QSFP mechanical and electrical specifications to ensure interoperability with compatible hardware platforms. It integrates high-quality optical and electronic components and supports digital diagnostics (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature. The design minimizes electromagnetic interference susceptibility typical for fiber links and provides a long service life with low maintenance requirements.

Suitable for

• 40G Ethernet uplinks and aggregation links in switches and routers
• High-capacity storage area networks and SAN interconnects
• Fiber channel over Ethernet and SDH/SONET deployments
• Data center spine/leaf architectures and carrier networks

How to use

Install the QSFP transceiver into a compatible QSFP slot on switches, routers or storage systems that support 40G QSFP modules. Connect an MPO/MTP single-mode patch cable to the module to establish the optical link. Verify that the host device firmware and software allow third-party transceiver modules and, if required, enable DDM/DOM access in the host to monitor module parameters. Observe standard ESD precautions during handling and avoid bending or stressing the optical fiber beyond its minimum bend radius.

Recommendations

For optimum performance, use single-mode MPO/MTP patch cords and, where possible, patch through appropriate panels or breakout assemblies to preserve signal quality. Confirm host compatibility and enable digital diagnostics to monitor link health. Keep transceiver contacts and fiber connectors clean and store spare modules in anti-static packaging when not in use.
