QSFP transceiver BlueOptics QSFP-40G-SR4-MM850-BO 40000 Mbit/s 850 nm

The BlueOptics QSFP-40G-SR4-MM850-BO is a QSFP fiber optic transceiver module designed for 40 Gbit/s data transmission over multimode fiber at a wavelength of 850 nm. The compact module weighs approximately 20 g and uses an MPO/MTP connector to support parallel optical links. It implements industry-standard QSFP electrical and mechanical interfaces and is intended for high-density deployments in data centers, aggregates and high-performance network equipment.

Advantages

This transceiver supports 40 Gbit/s multimode links with short-reach optics at 850 nm and is compliant with QSFP MSA form-factor conventions to ensure interoperability with compatible systems. The module’s lightweight, compact dimensions and MPO/MTP connectivity simplify installation in dense switch or router line cards. Built-in digital diagnostics (DDM/DOM) provide real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature for simplified maintenance and fault detection.

How to use

Insert the BlueOptics QSFP-40G-SR4-MM850-BO into a compatible QSFP slot on the switch, router or network device with the module keyed correctly. Connect an MPO/MTP multimode patch cable between transceivers or to a compatible patch panel; ensure cable polarity and fiber ribbon orientation follow the equipment vendor’s guidance. Verify that the host device recognizes the QSFP module and, if applicable, enable or monitor the module via the device management interface to read DDM parameters. Observe ESD precautions when handling and avoid contaminating optical interfaces.

Recommendations

Use high-quality OM3/OM4 multimode fiber and MPO/MTP patch cords for optimal reach and performance. Confirm host compatibility with QSFP modules and enable digital diagnostics on supporting hardware for proactive monitoring. Regularly inspect and clean MPO/MTP connectors before mating to prevent signal degradation and maintain link reliability.
