Cisco Original | 1000Base-SX | SFP | Hot-Swappable | DOM | Extended Temperature | Refurbished | GLC-SX-MMD

The GLC-SX-MMD is a hot-swappable Small Form-Factor Pluggable (SFP) transceiver that plugs into the Gigabit Ethernet port or slot on a switch or router and links the device with your fiber optic network. GLC-SX-MMD transceivers are an improved version of the GLC-SX-MM, in that they include Digital Optical Monitoring (DOM) and can tolerate an extended temperature range. They operate solely over multimode fiber (MMF) and can reach a distance of up to 1,000 meters. Our refurbished Cisco GLC-SX-MMD transceivers are a great option at a great price, and they come with a lifetime warranty and satisfaction guarantee.
