The AddOn GLC-SX-MMD-AO-5PK is a five-pack of Cisco-compatible 1GbE 1000Base-SX SFP transceivers for network teams connecting equipment over multimode fiber, with 850nm optics, LC connectors, DOM support, and reach up to 550m.
Recommended For
- Network teams linking Cisco switches over existing multimode fiber for 1-Gigabit Ethernet uplinks, when the switch, fiber type, and link distance support 1000BASE-SX.
- IT staff maintaining building or campus links that already use duplex LC multimode fiber and need a compatible 1-Gigabit SX optic rather than a copper or single-mode module.
- Administrators troubleshooting supported fiber links who want DOM-capable optics to read digital diagnostic information, provided their switch exposes that data for this module.
- IT departments deploying or keeping spares for several compatible links at once; the listing is a five-pack, so it suits multi-port rollouts better than a one-off replacement.
Real-World Use Scenarios
- Link two SFP-equipped switches across floors or between nearby wiring closets over existing multimode fiber; with compatible SX optics at both ends, the connection carries network traffic at 1 Gbps within the fiber’s supported reach.
- Reuse a building’s existing multimode fiber for a short campus or in-building link instead of installing a new cable run; check the fiber type and length first, since supported distance depends on the fiber.
- Replace or add 1-Gigabit fiber uplinks in a Cisco network that uses compatible SFP ports; verify the exact switch model supports the GLC-SX-MMD-compatible module before installation.
- Connect a switch’s SFP port to a fiber-capable media converter when the device at the other end lacks an SFP slot; use a matching SX transceiver and compatible multimode fiber on the link.
- Stock several transceivers for a multi-port rollout or as replacements; the five-pack can help standardize compatible 1-Gigabit multimode links, while DOM support can help administrators inspect optical-module status on supported equipment.
