Network transceiver for 20 km single-mode links

The Brute Networks 1442320G1 is a 1000BASE-LX SFP module built for single-mode fibre at 1310 nm. It delivers a 1 Gbps transfer rate over distances up to 20 km. The LC duplex connector fits standard SFP cages in switches and routers that require Adtran-compatible optics. Operating temperature spans 0 to 70 °C for commercial environments.

Steady throughput at 1 Gbps across the full 20 km

Under sustained load the module maintains line-rate gigabit traffic without burst-only behaviour. The 1310 nm wavelength and single-mode cable specification keep signal loss low across the entire reach. Front-panel LEDs show power, link activity, full-duplex status and speed so operators can verify continuous operation at a glance. MSA compliance ensures consistent interoperability with host equipment.

Direct replacement for Adtran 1442320G1 optics

This third-party transceiver matches the OEM part number 1442320G1 and meets or exceeds the original MSA specifications. It upgrades networks that need a cost-effective spare or expansion module without changing existing switch configurations. The jump is worth it when a compatible 20 km LX optic is required but the OEM price or lead time is a constraint. Buyers who need multi-mode reach or a different wavelength should look elsewhere.

Questions about this item

Does the 1442320G1 generate much heat or noise when running continuously at 1 Gbps?

The module operates passively with no fan, so it produces no audible noise and minimal heat within the 0 to 70 °C commercial temperature range.

What existing cabling and switch ports are required to use this SFP transceiver?

You need an LC duplex patch cord on single-mode fiber and a free SFP slot that supports 1000BASE-LX at 1310 nm.

Will this 20 km transceiver work alongside older 1000BASE-LX modules that only reach 10 km on the same link?

Both ends must use matched 20 km optics; mixing a 20 km module with a 10 km module will cause receive-level errors on the shorter-reach side.
