40 Gbps QSFP+ Transceiver for Long-Haul Links

This Brute Networks QSFP+ module delivers 40 Gbps over single-mode fibre using a 1310 nm wavelength. It is built for network engineers who need to bridge campus buildings or data-centre rows up to 10 km. The transceiver is coded for 100 % Cisco compatibility and meets MSA standards so it initialises identically to an OEM part in a router, switch or server.

Suited for 10 km Single-Mode Deployments

This module suits teams extending 40 GbE links across campus or metro single-mode fibre where 10 km reach and LC duplex connectors are required. It is not for buyers who need multimode connectivity, shorter-reach optics, higher-speed 100 GbE interfaces, or passive copper direct-attach cables for rack-local connections.

10 km Reach at 1310 nm Decides Fit

The single specification that determines suitability is the 10 km reach on 1310 nm single-mode fibre. If the link budget and distance match that figure, the transceiver will integrate with Cisco gear and third-party MSA slots; if the run is shorter, longer, or uses a different fibre type, another optic is required.

Questions about this item

Does the QSFP+ transceiver ship with the LC duplex patch cables needed for a 10 km single-mode link?

The module includes an LC duplex connector but patch cables are not supplied; you must order single-mode fiber cables with LC ends separately.

How do I decide between this 40 Gbps LR4 module and a shorter-reach alternative?

Choose this unit when the link spans up to 10 km over single-mode fiber; for shorter runs inside a data hall a lower-cost SR4 or eSR4 module is sufficient.

What does the 40 Gbps rating mean when the transceiver is installed in a live switch?

It delivers four 10 Gbps lanes at 1310 nm, giving a full 40 Gbps throughput over 10 km of single-mode fiber with digital diagnostics active.
