QSFP transceiver modul BlueOptics QSFP-40G-SR4-MM850-H-BO 40000 Mbit/s

The BlueOptics QSFP-40G-SR4-MM850-H-BO is a QSFP transceiver module designed for 40GBASE-SR4 fiber optic links. It supports a maximum data transfer rate of 40000 Mbit/s over multimode fiber and uses an MTP/MPO connector. The compact silver module weighs approximately 20 g and is intended for short-range high-speed connections up to 150 m when paired with appropriate multimode cabling and compliant hardware.

Advantages

This QSFP transceiver follows MSA mechanical and optical specifications for 40GBASE-SR4 operation and provides interoperable MPO/MTP connectivity for parallel multimode fiber systems. The module integrates 850 nm transmit and receive elements suitable for Ethernet and related high-speed protocols, and it supports digital diagnostic monitoring (DDM/DOM) for real-time status of supply voltage, laser bias current, optical power and temperature. Built with standardized components, the transceiver is optimized for predictable lifetime and stable optical performance in data center and enterprise networks.

How to use

Install the BlueOptics QSFP-40G-SR4-MM850-H-BO into any compatible QSFP slot following the host platform vendor instructions for hot-pluggable transceivers. Connect the module to an MPO/MTP multimode fiber assembly that meets the required fiber specification (OM3/OM4 as appropriate) and ensure correct polarity and connector alignment. Configure the host port for 40G operation and verify link negotiation through the switch or router management interface. Monitor the module status and optical parameters using the DDM/DOM interface if supported by the host device.

Recommendations

Use certified multimode patch cords and MPO/MTP trunk cables, maintain clean connectors, and verify that the host hardware supports 40GBASE-SR4 and DDM/DOM features. For best performance, choose OM3 or OM4 multimode fiber for links approaching the maximum 150 m distance and follow manufacturer guidance for cable management and connector cleaning.
