Cisco GLC-LX-SM-RGD

Overview

The Cisco GLC-LX-SM-RGD is a rugged Small Form Factor Pluggable (SFP) transceiver designed to provide a reliable 1 Gigabit Ethernet fiber connection for compatible Cisco switches and routers. Operating at a 1310 nm wavelength and compliant with the IEEE 802.3z 1000BASE-LX standard, it supports data transmission over distances up to 10 km on single-mode fiber and 550 m on multimode fiber. This makes it an excellent solution for extending network links to remote locations where copper cabling is impractical.

Its hot swappable design allows for easy installation and replacement without powering down the host device, minimizing network downtime. Built to withstand harsh environments, this transceiver is well suited for industrial settings, roadside cabinets, and factory floors.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
