Fiber optic transceiver module BlueOptics SFM-40G-SR4-BO 40000 Mbit/s QSFP

The BlueOptics SFM-40G-SR4-BO is a fiber optic transceiver module designed for high-speed data transfer with a QSFP interface and a maximum data rate of 40000 Mbit/s. It supports multimode fiber connections using an MPO/MTP connector and implements 40GBASE-SR4 optical signalling with 850 nm transmit and receive wavelengths. The transceiver is supplied in a compact, lightweight silver housing and is intended for integration into networking equipment that accepts QSFP form-factor modules.

Advantages

This module provides 40 Gbit/s optical connectivity over multimode fiber with an MPO/MTP interface, enabling simultaneous transmit and receive channels within the QSFP form factor. It is built to industry MSA standards and is tested for compatibility with systems that support comparable 40GBASE-SR4 QSFP transceivers. The design emphasises long operational life and monitoring capability: the module supports digital diagnostics (DDM/DOM) for real-time access to parameters such as supply voltage, laser bias current, transmit output and receive input power, and temperature.

How to use

Install the BlueOptics SFM-40G-SR4-BO by inserting the QSFP module into a compatible QSFP port on your switch, router or other network device while the host supports 40GBASE-SR4 transceivers. Connect an MPO/MTP multimode fibre patch cord to the module and to the corresponding port or patch panel on the remote device. Ensure that the connected multimode fibre type and channel configuration match the 4-lane SR4 signalling. If required, enable or verify support for digital diagnostics on the host to monitor operating parameters. Follow the host vendor’s hot-plug and safety procedures when inserting or removing the module.

Recommendations

Verify system compatibility with the host hardware and software before deployment, use appropriate MPO/MTP multimode patch cords and patch panels, and confirm that the fibre type and channel mapping correspond to SR4 multimode connections. Monitor DDM/DOM parameters to assist with installation, troubleshooting and ongoing link maintenance.
