Module for Cisco 1000BASE-SX SFP GBIC Module You don't have to let a lack of transceiver modules stop you from getting the highest speeds out of your Cisco Catalyst devices anymore because we've got Cisco compatible GLC-SX-MM small form factor optics for low prices. These Cisco SFP modules are made to improve the data transfer rates of Cisco switches and routers in the time it takes to hot-swap them in, so you can instantly rebuild your network better, faster and more reliable than it was before. The Gencom GLC-SX-MM GBIC accepts any standard Ethernet 1000Base-SX LC/PC multi-mode fiber (MMF) cables you have, but unlike some transceivers, it has ports to accept two of them at once. Additionally, this module works equally well with 50 um MMF and 62.5 um FDDI-grade MMF. It's compliant with the IEEE 802.3z standards, meaning that it transmits data at a whopping 1 Gbps and can send information up to 0.6 miles using 850 nm optical pulses. The transceiver fits into any unpopulated SFP slot that adheres to the mini-GBIC standards, thus making it compatible with a lot of different network devices. This module works with Integrate Services Routers, Branch Office in a Box Bundles, Secure WAN Optimization Bundles, WAN Application Acceleration Bundles, Router WAN Optimization Bundles, Voice S(more...)
