Cisco Rugged 1000Base-SX 1GbE 850nm SFP Transceiver Module

The Cisco GLC-SX-MM-RGD is a small form factor pluggable transceiver that brings 1 Gigabit Ethernet fiber connectivity to compatible Cisco switches and routers. It follows the 1000Base-SX standard and operates at an 850 nm wavelength, which lets it move data over multimode fiber runs up to 1800 feet (550 meters on legacy 50 µm fiber) without signal degradation.

Installation takes only a moment because the module is hot swappable. Network technicians can add or replace it while the equipment stays powered, keeping downtime to a minimum during upgrades or maintenance.

A rugged housing protects the optics in environments where temperature shifts, vibration, or dust might challenge less durable hardware. This makes the module a practical choice for factory floors, transportation hubs, outdoor enclosures, or any site that demands industrial strength networking gear.

The LC/PC connector locks firmly into standard multimode fiber cabling, and compliance with IEC 60825-1 Class 1 laser safety standards supports safe operation in public or private facilities. Compatibility extends across many Cisco platforms, including the Cisco 2010, 2520, and Catalyst 2960 series, so a single spare can serve multiple models on the same network.

Cisco backs the transceiver with a one-year limited warranty, giving administrators confidence that the link they depend on will continue to perform.
