What it is

The Brute Networks GLC-SX-MM is a 1000BASE-SX SFP transceiver built for multi-mode fibre links up to 550 metres at 850 nm. It plugs into any standard SFP slot on a router, switch or server and delivers a 1 Gbps connection with LC duplex cabling.

Who it suits

Network engineers who need a cost-effective way to populate Cisco SFP ports with a module that initialises identically to the OEM part and carries Digital Output Monitoring. It is not for links that exceed 550 metres, single-mode fibre infrastructures, or line rates above 1 Gbps.

Deciding specification

The 550 metre reach on multi-mode fibre at 850 nm is the single figure that determines whether this transceiver matches the link budget and cable plant in your deployment.

Highlights

Questions about this item

How much heat does the 1000BASE-SX 850 nm SFP generate when running continuously at 1 Gbps?

The module operates within a commercial temperature range of 0 to 70 °C, so it stays cool enough for standard rack or switch environments without extra cooling.

What patch cable and switch port does the LC duplex SFP need to work?

You need a multi-mode fibre patch cord with LC duplex connectors and an open SFP slot that supports 1000BASE-SX at 850 nm.

Will this 550 m transceiver link reliably with legacy 1000BASE-SX gear already in the rack?

Yes, it is fully MSA compliant and coded for Cisco compatibility, so it initialises and performs identically to OEM 1000BASE-SX modules in the same link.
