Network transceiver module BlueOptics BO25K856S2D-BO 40 Mbit/s QSFP

The BlueOptics BO25K856S2D-BO is a network transceiver module engineered for data transfer at 40 Mbit/s. It uses a QSFP interface and an LC fiber optic connector to provide a stable optical link, and its compact design with a weight of 40 g facilitates installation in compatible network equipment. The module is finished in grey and is intended for integration where a QSFP form factor and optical connectivity are required.

Advantages

The QSFP interface supports straightforward hot-pluggable installation in devices that accept QSFP modules. Optical LC connectivity reduces electromagnetic interference and offers reliable signal transmission over fiber. The module’s low weight and compact dimensions make it suitable for dense rack and chassis environments where space and weight are considerations. Its fixed transfer rate simplifies configuration in networks that operate at the specified speed.

How to use

Ensure the host device supports QSFP transceiver modules and operates at the specified data rate. Power down the host or follow the vendor’s hot-swap procedure, then insert the module into a compatible QSFP slot until it seats securely. Connect an LC fiber optic cable to the module’s connector, observing correct polarity. After installation, verify link status through the host device’s management interface and confirm the 40 Mbit/s link is active. Follow standard safety practices for handling fiber optics and electrostatic-sensitive components.

Recommendations

Use the transceiver in equipment certified to accept QSFP modules and operate within the manufacturer’s specified environmental and electrical limits. Maintain clean fiber connectors to ensure optimal signal quality and periodically inspect connectors for dust or damage. For network planning, match the module’s 40 Mbit/s rate with the rest of the link to avoid mismatched speeds.
