AddOn Cisco GLC-SX-MM-RGD Compatible 1000Base-SX SFP Transceiver (MMF, 850nm, 550m, LC, DOM, Rugged)

The AddOn GLC-SX-MM-RGD-AO is a Cisco-compatible, hot-swappable 1Gbps 1000Base-SX SFP transceiver for network professionals connecting compatible Cisco equipment over multimode fiber, with an LC duplex port and a listed reach of up to 550m.

Recommended For

• Network teams maintaining Cisco industrial Ethernet or connected-grid links can use it as a 1-Gigabit multimode fiber optic for supported equipment; verify the exact switch or router model’s SFP compatibility before ordering.
• Operators connecting equipment in outdoor, factory-floor, or other wide-temperature locations can choose this rugged SX optic when their network uses compatible multimode fiber and needs a 1-Gigabit link.
• Technicians extending a short-reach fiber uplink between switches or network devices can use it on existing 850-nm multimode fiber, with reach depending on the cable type and quality.
• Maintenance teams that want digital optical monitoring can consider it for supported platforms that can read DOM data, helping them inspect the optic’s reported link conditions.

Real-World Use Scenarios

• In an industrial network, use it as a fiber uplink from a compatible Cisco IE 3000 switch to another network device; it provides a 1-Gigabit connection over multimode fiber, with the link distance depending on the cable grade.
• For a compatible industrial switch installed in a temperature-variable area, choose this rugged-compatible optic when the network design calls for a multimode fiber uplink; the supported temperature range depends on the specific switch and transceiver.
• When connecting a production-area switch to a nearby network closet over existing multimode fiber, this module can provide a 1-Gigabit optical link if both ends use compatible optics and the cable supports the required distance.
• In a supported Cisco connected-grid or industrial routing setup, use it to connect a compatible router or switch to a nearby multimode-fiber network segment; it suits short-reach 1-Gigabit links, not long single-mode runs.
