Rugged SFP for Multi-Mode Fibre

The Cisco GLC-SX-MM-RGD= is a hot-swappable 1000BASE-SX transceiver built for Gigabit Ethernet links over 62.5 µm multi-mode fibre. It serves network engineers and integrators who need a reliable, standards-based module for campus or industrial LAN uplinks.

LC Duplex Connector and 850 nm Operation

A single LC/PC duplex connector carries both transmit and receive paths at an 850 nm wavelength. The ruggedised housing withstands harsher environments than standard SFPs while the hot-swap design allows insertion or removal without powering down the switch, reducing maintenance windows.

Replaces Standard SX Modules in Demanding Sites

This unit upgrades a conventional 1000BASE-SX SFP when extended temperature range or vibration resistance is required. The jump is worth it for deployments in unconditioned cabinets, outdoor enclosures or factory floors where a commercial-grade transceiver would risk premature failure.

Questions about this item

What distance does the 850nm wavelength support over 62.5 µm multi-mode fiber?

The 850nm wavelength supports up to 1800 ft over 62.5 µm multi-mode fiber at 1 Gbps.

What connector type does the GLC-SX-MM-RGD= use for physical mounting?

It uses a single LC/PC duplex connector that plugs directly into a compatible SFP port.

How is this hot-swappable transceiver installed without disrupting the network?

Insert the module into an active Gigabit Ethernet SFP slot until it clicks; the port remains online during insertion.
