40GBASE-PLR4 QSFP+ 10 km

This 40 Gbps QSFP+ transceiver is built for Arista switches and routers that need a 10 km single-mode link at 1310 nm. It plugs into any standard QSFP+ port and is coded to initialise exactly like the OEM module. The part is new and carries a lifetime warranty from Brute Networks.

Suited for 10 km single-mode runs.

Network engineers extending campus or metro links over duplex single-mode fibre will find the 10 km reach and MTP/MPO connector a direct fit. Buyers whose infrastructure uses multimode fibre or who need a reach shorter than 2 km should look at other form factors because this module is optimised for long-haul single-mode only.

1310 nm wavelength on single-mode fibre

The laser operates at 1310 nm over single-mode cable, delivering 40 Gbps across 10 km with digital diagnostic monitoring built in. This wavelength and distance combination is the deciding factor when matching the transceiver to your existing fibre plant.

Questions about this item

Does the MTP/MPO connector or the 1310nm laser need periodic cleaning or replacement?

The MTP/MPO connector should be inspected and cleaned with lint-free wipes before each mating; the 1310nm laser is sealed and requires no scheduled replacement.

What limits continuous 40 Gbps throughput over 10 km single-mode fibre?

The 10 km reach and 1310nm wavelength define the link budget; signal attenuation beyond that distance becomes the first throughput constraint.

How much heat does the module add inside a fully loaded switch chassis at 70 °C ambient?

Commercial temperature rating 0–70 °C and MSA-compliant power draw keep thermal load within standard QSFP+ slot limits during all-day operation.
