Fiber optic transceiver BlueOptics QSF-502-BO 40000 Mbit/s QSFP 850 nm

The BlueOptics QSF-502-BO is a QSFP fiber optic transceiver module designed for 40 Gbit/s links using 850 nm optics. It supports multimode fiber with an MPO/MTP connector and follows MSA-compliant QSFP form-factor specifications. The module offers digital diagnostics monitoring (DDM/DOM) compatibility where supported by the host hardware, a compact silver housing and a lightweight design of approximately 20 g. With a rated mean time between failures (MTBF) of 1,000,000 hours and RoHS compliance, the transceiver is intended for high-availability network environments requiring 40G short-range optical connectivity.

Advantages

The module provides 40GBASE-SR4 performance for short-range multimode links up to the supported distance of the installed fiber infrastructure, using a standardized QSFP interface for straightforward insertion into compatible ports. Built to MSA standards and tested for compatibility with major hardware platforms, it includes DDM/DOM support for remote monitoring of optical and electrical parameters when the host supports these features. Its compact, silver metal housing and low weight simplify handling and installation in dense rack environments.

How to use

Install the BlueOptics QSF-502-BO by inserting the QSFP module into a compatible QSFP port on the switch, router or storage device while the host is powered according to the vendor’s instructions. Connect the MPO/MTP multimode fiber patch cord to the module and route the fiber to the corresponding transceiver or patch panel. If the host supports DDM/DOM, enable or query the diagnostic interface via the device management system to monitor supply voltage, laser bias current, transmit power, receive power and temperature. Follow the network equipment manufacturer’s guidelines for hot-plugging, ESD precautions and firmware compatibility when fitting the module.

Recommendations

Use high-quality multimode fiber (OM3/OM4) and MPO/MTP patch cords rated for 40GBASE-SR4 to achieve the expected short-range performance. Verify host compatibility and software or firmware settings before deployment, and monitor DDM/DOM data to detect degradation early. Maintain proper fiber bend radius and clean MPO/MTP connectors before insertion to ensure optimal optical performance.
