GLC-SX-MM-RGD Description
GLC-SX-MM-RGD is a Cisco 1000BASE-SX rugged SFP optical transceiver for Gigabit Ethernet links over multimode fiber in industrial Cisco environments and supported Cisco SFP host platforms. It provides short-wavelength 1G optical connectivity with dual LC/PC connectors, 550 m maximum reach, an 850 nm wavelength class, DOM support, and an industrial temperature class for deployments that need a ruggedized SX optic rather than a standard commercial-temperature SFP.

Application Scenarios
GLC-SX-MM-RGD fits orders where the documented Cisco host accepts a GE SFP and the plant fiber is multimode. The rugged SX line item keeps the BOM away from commercial SX optics when the enclosure or platform plan calls for industrial-temperature parts.
Use this SKU for 1000BASE-SX links that stay within the Cisco 550 m value shown in supported-module tables. If the same site needs LX/LH reach or single-mode fiber, quote GLC-LX-SM-RGD as a separate rugged fiber option.
Maintenance kits can include GLC-SX-MM-RGD beside rugged LX/LH or ZX modules only when each media role is labeled. The receiving team should still validate the exact Cisco host, software support, fiber type, and DOM requirement before staging the module.

GLC-ZX-SM-RGD |
- In a GLC-SX-MM-RGD vs GLC-SX-MMD comparison, both are Cisco 1000BASE-SX MMF SFP optics with DOM, but GLC-SX-MM-RGD is the industrial-temperature rugged choice while GLC-SX-MMD is the extended-temperature SX choice.
- The GLC-SX-MM-RGD difference from GLC-LX-SM-RGD is fiber standard and reach: GLC-SX-MM-RGD stays on 1000BASE-SX MMF at 550 m, while GLC-LX-SM-RGD covers 1000BASE-LX/LH over MMF or SMF.
- For a GLC-SX-MM-RGD vs GLC-ZX-SM-RGD comparison, the order changes from short-wavelength MMF to rugged 1000BASE-ZX SMF with an approximately 70 km link-loss-dependent reach.
- For which model to choose, start with the required fiber media and reach, then confirm temperature class, DOM support, connector type, and the Cisco host support table.
Selection Guide
1. Select it for rugged SX multimode links
Choose GLC-SX-MM-RGD when the bill of materials specifies Cisco 1000BASE-SX over multimode fiber and the deployment requires an industrial-temperature SFP line item.
2. Keep extended-temperature SX separate
Use GLC-SX-MMD only when the same 1000BASE-SX MMF role is acceptable with Cisco’s extended-temperature class. Substituting it for GLC-SX-MM-RGD changes the environmental assumption on the order.
3. Move to rugged LX or ZX only for the fiber plan
Move to GLC-LX-SM-RGD when the order needs rugged LX/LH behavior over MMF or SMF, and move to GLC-ZX-SM-RGD only for rugged 1000BASE-ZX SMF reach. Those SKUs do not replace a short-reach SX MMF requirement.
4. Verify host approval before release
Check the Cisco compatibility matrix or the target platform support table before approval because SFP support is tied to the device, port role, and software release.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Host support |
Cisco device, SFP port role, and software release |
Confirms the optic is supported in the intended hardware before it is staged |
|
Fiber media |
Multimode fiber path for 1000BASE-SX |
Avoids substituting an SMF-focused LX/LH or ZX rugged module |
|
Reach planning |
550 m maximum distance from Cisco supported-module tables |
Keeps patching and fiber design inside the confirmed SX value |
|
Connector and monitoring |
Dual LC/PC connector and DOM support expectations |
Sets the receiving and monitoring checks before installation |
|
Temperature class |
Industrial SFP requirement for the target enclosure or platform |
Prevents replacement with an extended or commercial temperature SKU when the rugged line item matters |
