Adds a 100 Mbps fibre link up to 2 km using 1310 nm multi-mode optics in an industrial-temperature SFP module
This Brute Networks transceiver delivers 100 Mbps connectivity over multi-mode fibre using a 1310 nm wavelength and LC duplex connectors. It is built to the MSA form factor and coded for full Cisco GLC-FE-100FX-RGD compatibility so it initialises identically to the OEM module in routers, switches or servers. Industrial-grade components allow operation from minus 5 to 85 °C.
Engineers extending 100BASE-FX links to the full 2 km specification will find this module a direct, cost-effective fit. It is not intended for single-mode fibre runs, for gigabit or faster Ethernet speeds, or for installations that require a different wavelength or connector type.
The decisive specification is the 2 km maximum distance at 1310 nm over multi-mode optical fibre; if your link budget or cabling plant demands a different reach, wavelength or fibre type, this transceiver will not meet the requirement.

The module uses an LC duplex connector for multi-mode fibre.
Remove the dust caps, align the keyed LC duplex connector with the SFP cage, and push until it clicks; forcing it before the latch engages is the common mistake.
The unit is rated for continuous operation up to 85 °C; if the chassis regularly runs near that limit, schedule a swap before the laser degrades.
