SFP Transceiver Module StarTech GLC-SX-MM-RGD — 1000BASE-SX, Multimode LC, 850 nm, 550 m, 1GbE, DDM

The StarTech GLC-SX-MM-RGD SFP transceiver module provides 1000BASE-SX fiber connectivity for multimode networks. Designed for use in SFP ports on switches and routers, it operates at an 850 nm wavelength with LC duplex connectors and supports up to 1 GbE (maximum 1250 Mbit/s) over multimode fiber to distances up to 550 m. The module comes in a compact aluminium housing with a silver finish and is suitable for enterprise and campus network links that require hot-swappable, low-power fiber uplinks.

Advantages

The module supports 1000BASE-SX standards and is compatible with a wide range of SFP ports, offering a compact form factor and typical power consumption under 1 W. Its aluminium housing provides durability while keeping weight minimal. The unit includes support for digital diagnostics monitoring where applicable and has a high MTBF value for continuous operation, making it appropriate for deployments that prioritize stable fiber connectivity and easy field replacement.

Suitable for

• Short-range multimode fiber links between switches and servers within buildings or across campus facilities
• Upgrading copper uplinks to 1 GbE fiber connections in enterprise and education networks
• Hot-swappable replacements or expansions in SFP-compatible routers and switches

How to use

Power down the port or follow your equipment vendor’s hot-swap procedure if required, then insert the SFP module into an available SFP port until it seats securely. Connect LC multimode fiber duplex cables (observe transmit/receive orientation) to the module and to the corresponding device. Verify link status via the switch or router management interface and confirm the port negotiates at 1 GbE. For safe removal, follow your network device’s instructions to prevent transient link issues.

Usage recommendations

Use multimode fiber of the appropriate OM grade recommended for 850 nm operation and ensure connectors are clean before insertion. Check compatibility lists for your specific switch or router model and use the transceiver in environments within the stated operational parameters. For critical links, monitor link status and diagnostics where supported and keep a spare module on hand for rapid replacement.
