40GBASE-LR4 QSFP+ for 10km links

This Brute Networks transceiver delivers 40 Gbps over single-mode fibre at 1310nm wavelength. It is built for network engineers extending Cisco switches or routers across campus or metro distances up to 10km. The module is coded for full Cisco compatibility and meets MSA standards for interoperability with other compliant optics.

Hot-plug installation with LC duplex

The QSFP+ form factor slides into a compatible port without tools or system reboot. Digital output monitoring provides real-time diagnostics for power, link status, and speed verification. The main risk is contaminating the LC duplex connector end-faces; always clean with a lint-free wipe and inspect before mating to avoid insertion loss.

Verify switch port and fibre plant

Confirm the host device lists QSFP-40GE-LR4 or 40GBASE-LR4 in its supported transceiver matrix before ordering. Ensure your single-mode fibre run uses LC duplex patch cords and does not exceed the 10km reach budget. The module operates from 0 to 70 Celsius, so check that the chassis airflow meets commercial temperature limits.

Questions about this item

How do I confirm the module is operating correctly after installation?

Check the Power, Link/Activity, Full-Duplex and Speed LEDs on the transceiver; Digital Output Monitoring also reports real-time status.

What ships with the transceiver and what must I supply?

The module includes an LC duplex connector; you must provide single-mode fibre patch cables and a compatible QSFP+ port.

Which wavelength and reach should I select for a 10 km single-mode link?

Choose the 1310 nm, 10 km version — it matches the 40 Gbps LR4 standard for that distance.
