40 Gbps QSFP+ LR4 transceiver

The Brute Networks X140Product is a 40 Gbps QSFP+ LR4 transceiver built for 10 km links over single-mode fiber at 1310 nm. It targets network engineers who need a drop-in module for HPE JG661A ports in data-centre and campus switches.

Replaces HPE JG661A at lower cost

This third-party module meets the same 40GBASE-LR4 specification and MSA industry standards as the OEM part, so the upgrade is worthwhile when budget constraints rule out list-price optics but compatibility and commercial-temperature operation remain mandatory.

10 km reach with standard LC duplex

The LC duplex interface supports 10 km on OS2 single-mode fiber, handling 40 Gbps Ethernet traffic across building interconnects or metro spans. Beyond 10 km the optical budget is exceeded, so longer-haul designs must select a different wavelength or amplification scheme.

Highlights

  • 10 km reach over single-mode fibre

  • 1310 nm wavelength for long-range links
  • 0 – 70 °C commercial temperature range
  • 100 % HPE JG661A compatible part

Questions about this item

What connector type does the X140 40G QSFP+ LR4 transceiver use for single-mode fiber?

The transceiver uses an LC duplex connector for single-mode fiber connections.

How is the QSFP+ module inserted into the switch port, and what step is often missed?

Align the module with the QSFP+ cage, push firmly until the latch clicks, then remove the dust caps before connecting cables.

When should the optical interfaces be cleaned on this 10km 1310nm module?

Clean the LC ferrules with a lint-free swab and isopropyl alcohol whenever signal loss appears or during scheduled fiber maintenance.
