BlueOptics TN-QSFP-40G-SR4-BO network transceiver module 40000 Mbit/s 850 nm

The BlueOptics TN-QSFP-40G-SR4-BO network transceiver module is a QSFP fiber optic module engineered for multi-mode fiber links with a nominal wavelength of 850 nm and a maximum data transfer rate of 40000 Mbit/s. Housed in a durable metal enclosure and rated for 3.3 V input, the module is a compact, lightweight component suitable for high-density networking equipment. It uses an MPO/MTP-style optical interface according to MSA standards and supports short-reach 40GBASE-SR4 optical connections over multi-mode fiber.

Advantages

The module provides 40 Gbit/s optical connectivity in a QSFP form factor, enabling high-throughput links between switches, routers and storage systems without susceptibility to electromagnetic interference. Its metal housing offers mechanical stability and thermal conduction while the standardized QSFP and MPO/MTP interfaces simplify integration into systems that accept 40GBASE-SR4 transceivers. The product supports digital diagnostics (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, transmitted and received optical power, and internal temperature when the host hardware exposes these functions.

How to use

Insert the BlueOptics QSFP transceiver into a compatible QSFP slot on the host device following the device manufacturer’s hot-plug instructions. Connect an MPO/MTP multimode fiber patch cable to the transceiver’s optical port, observing correct polarity and fiber type for 40GBASE-SR4 links. Ensure the host device supports the module’s DDM/DOM functions if you intend to use digital diagnostics. After installation, verify link status and optical parameters through the host system management interface.

Recommendations

Use OM3 or OM4 multimode fiber and high-quality MPO/MTP patch cords for optimal reach and performance. Confirm compatibility with the target hardware and firmware, keep fiber connectors clean, and follow ESD precautions when handling the module to maintain reliability and minimize insertion loss.
