CISCO GLC-SX-MM-RGD= 1000BASE-SX SFP 1 Gbps 1 x LC/PC Duplex Connector 1000Base-SX

The Cisco GLC-SX-MM-RGD= is a 1 Gbps 1000BASE-SX SFP transceiver with an 850 nm wavelength and duplex LC/PC connector, suited to network teams linking compatible equipment over multimode fiber for runs up to 1,800 ft.

Recommended For

• Industrial-network teams linking Cisco industrial switches over existing multimode fiber, when they need a 1-Gigabit Ethernet connection in environments that call for rugged-rated optics.
• Network installers extending a Gigabit link between switches or network devices over an existing multimode-fiber run with duplex LC connections.
• Operators maintaining Cisco industrial or ruggedized network equipment who need an SX optic matched to a supported host and multimode-fiber link.
• Teams replacing or matching an existing GLC-SX-MM-RGD optic in a 1-Gigabit multimode-fiber link, while checking the switch or router’s transceiver support before deployment.

Real-World Use Scenarios

• Connecting two compatible industrial switches over existing multimode fiber—for example, between a production-floor cabinet and a control-room network—provides a 1-Gigabit Ethernet link without extending copper between them.
• Adding a fiber uplink to a switch in an industrial equipment cabinet lets nearby networked devices reach the site network; the rugged-rated optic is intended for industrial environments, provided the switch supports this specific module.
• Linking switches across a plant or building where multimode fiber is already installed can reuse that cabling for a Gigabit Ethernet connection; the achievable reach depends on the fiber type and its condition.
• Replacing a failed SX optic in a supported industrial Cisco switch can restore a multimode-fiber network link; checking the switch’s compatibility documentation first helps avoid using an unsupported rugged SFP.
