QSFP transceiver module BlueOptics 321-1837-BO 40000 Mbit/s

The BlueOptics 321-1837-BO is a QSFP fiber optic transceiver module designed for 40 Gigabit Ethernet links. It supports a maximum data transfer rate of 40000 Mbit/s and a maximum transfer distance up to 10000 m using LC fibre connectors. The module has a compact QSFP form factor, a silver housing and a lightweight construction of approximately 20 g, delivering a high MTBF rating of 1,000,000 hours suitable for continuous network operation.

Advantages

The QSFP transceiver provides standardized 40 Gigabit Ethernet connectivity in a single compact module and is compatible with systems that accept QSFP form-factor optics. The LC connector interface enables multi-mode or single-mode fibre termination options depending on system configuration. Its low weight and silver metal housing aid thermal dissipation and mechanical robustness for rack-mounted and chassis-based networking equipment. The specified MTBF indicates a design focused on long-term reliability under normal operating conditions.

Suitable for

• High-speed server-to-switch connections in data centres
• Aggregation and spine-leaf switching topologies
• Long-distance optical links up to 10 km
• Upgrading network uplinks to 40 Gigabit Ethernet

How to use

Ensure the host device supports QSFP modules and 40 Gigabit Ethernet optics before installation. Power down or follow hot-swap procedures for your equipment according to the vendor instructions. Align the module’s QSFP guide rails and slide it into the transceiver slot until it seats firmly; connect LC-terminated fiber patch cables to the LC ports. After insertion, verify link and speed negotiation in the switch or network interface management interface and monitor optical signal levels. Follow system vendor guidance for any required firmware or port configuration to enable the 40 Gbit/s link.

Recommendations

Store and handle the transceiver in a clean, dry environment; avoid touching the LC connector endfaces and use dust caps when the module is not in use. Use compatible LC fiber patch cords rated for the intended link distance and fibre type. Monitor module operating temperature and optical power levels as part of routine network maintenance to ensure stable 40 Gigabit Ethernet performance.
