Fiber optic transceiver module BlueOptics AT-QSFPSR4 QSFP 850 nm MPO

The BlueOptics AT-QSFPSR4 QSFP 850 nm MPO is a compact fiber optic transceiver module designed for 40G multimode applications. Operating at 850 nm with an MPO connector and a QSFP interface, this module supports high-speed optical links over multimode fiber for short-reach data centre and enterprise networks. The transceiver is lightweight (approx. 20 g) and engineered for hot-plug installation in compatible QSFP ports that follow MSA guidelines.

Advantages

The BlueOptics AT-QSFPSR4 provides interoperability with MSA-compliant QSFP ports and supports simultaneous transmit and receive channels via MPO/MTP termination. Designed for multimode fiber, it enables high aggregate throughput suitable for 40G applications while minimizing electromagnetic interference inherent to copper links. The module is manufactured using components that meet industry reliability standards and includes digital diagnostic monitoring capability when supported by the host hardware.

How to use

Install the module into a compatible QSFP port following the host equipment manufacturer’s instructions and ESD handling precautions. Connect an appropriate MPO/MTP multimode fiber patch cord to the transceiver taking care to align polarity and connector keying. Verify link status and, if available, read digital diagnostic monitoring parameters through the host management interface to confirm proper operation. For best results, ensure fiber optic patch cords, patch panels and transceivers are cleaned and inspected before making the connection.

Recommendations

Use OM3 or OM4 multimode fiber for optimal reach and performance with 40GBASE-SR4 deployments, and ensure the host equipment firmware supports third-party QSFP modules and DDM access if diagnostics are required.
