Cisco GLC-SX-MM-RGD 1Gbps 850nm Transceiver

Slow network upgrades can leave your data centre struggling to keep up with demand. The Cisco GLC-SX-MM-RGD 1Gbps 850nm Transceiver is a hot-swappable SFP module that gives you reliable 1 Gbps fibre connectivity over multimode cable, letting you extend or replace Ethernet links without costly downtime. It fits Cisco equipment that supports 1000BASE-SX, delivering a simple, cost-effective solution for high-speed campus or data-centre networks.

Cisco GLC-SX-MM-RGD 1Gbps 850nm Transceiver - the practical fix for fibre link limits

When a network’s fibre run exceeds the reach of older optics, performance drops and errors increase, jeopardising applications that rely on steady bandwidth. This matters because any interruption can affect productivity, cloud services and VoIP quality. The Cisco GLC-SX-MM-RGD 1Gbps 850nm Transceiver solves the issue by providing a dedicated 850 nm laser that works reliably on 50 µm multimode fibre up to 550 m and on 62.5 µm FDDI-grade fibre up to 220 m, ensuring a clear, high-speed path for your traffic. It integrates seamlessly with Cisco switches and routers that accept SFP modules, giving you a plug-and-play upgrade that keeps your network running smoothly.
