Sieťový QSFP transceiver BlueOptics BO25K13640D 40GBASE-ER4 40 km

The BlueOptics BO25K13640D QSFP transceiver implements the 40GBASE-ER4 standard to provide 40 Gbps optical links over single-mode fiber for distances up to 40 km. Designed for use in data centers and telecom aggregation sites, this QSFP module fits standard QSFP ports on switches, routers and optical equipment to enable long-reach, high-bandwidth interconnects. The module supports plug-and-play installation to simplify upgrades and deployment of 40G infrastructure.

Advantages

This 40GBASE-ER4 transceiver delivers long-reach connectivity over single-mode fiber with low insertion complexity and high compatibility with QSFP form-factor interfaces. It enables consolidation of multiple 10 Gbps lanes into a single 40 Gbps link, reducing cable count and port usage while maintaining low latency and stable performance over extended distances. The module’s standardized optical specifications ensure predictable link budgeting for network planning.

How to use

Install the QSFP transceiver into a compatible QSFP port on your switch, router or optical device until it clicks into place. Connect single-mode fiber patch cords to the module’s optical interface using the appropriate connectors and ensure the opposite end is terminated to a matching 40GBASE-ER4 link partner. Verify that the host device recognizes the module and monitor link status and optical parameters via the device management interface. Follow standard handling precautions for electrostatic discharge and avoid bending the fiber beyond recommended radii.

Recommendations

For reliable long-reach performance, verify end-to-end attenuation and dispersion budgets for single-mode fiber spans approaching 40 km, use quality single-mode patch cords and maintain proper fiber routing. Confirm compatibility with the host equipment vendor’s supported transceiver list and monitor optical power and error statistics after deployment.
