Industrial-Grade Long-Reach SFP

This Brute Networks 1000BASE-EX transceiver delivers 1 Gbps connectivity over single-mode fibre at a 1310 nm wavelength. It is built for network engineers who need reliable 40 km links in harsh environments, with an operating range of -5 °C to 85 °C. The module fits standard SFP slots and includes digital output monitoring for real-time link diagnostics.

Replaces Standard-Range Optics

Use this module when the distance between sites exceeds the reach of typical SX or LX transceivers and a 40 km span is required. The jump is worth it for campus backbones, metro Ethernet rings or remote cabinet uplinks where standard optics fall short. It is not suited for deployments needing only a few hundred metres or for multi-mode fibre plants.

Plug-and-Play with LC Duplex

Installation is a simple hot-swap into any MSA-compliant SFP port using an LC duplex patch cord; no configuration is needed on most Cisco platforms. The most common issue is mismatched single-mode patch leads or dirty end-faces, which cause immediate link loss. Always verify the Tx/Rx fibre polarity before powering the link.

Questions about this item

Does the SFP module use an LC duplex connector for single-mode fibre?

Yes, the transceiver has an LC duplex connector designed for single-mode optical fibre.

What temperature range must the switch or router chassis support for this industrial-grade module?

The module operates from -5 to 85 °C, so the host equipment must tolerate that industrial range.

When should the transceiver be replaced if digital optical monitoring shows declining signal levels?

Replace it when DOM-reported receive power drops toward the sensitivity limit for 40 km reach at 1 Gbps.
