Module for Cisco 1000BASE-LX/LH SFP GBIC Module Let’s go over the basics of the Gencom GLC-LH-SM. This module is hot-swappable intended for a wide range of Cisco routers and switches. It is IEEE 802.3z-compliant and has different operating limits with each type of compatible fiber. If you use standard single mode fiber optic links, you can transmit data up to 10 km (6.2 miles), but with multi mode fiber links, connections are limited to 550 m (1804 ft). This GBIC transceiver transmits at the standard optical wavelength of 1310 nm in order to provide data transfer rates of up to 1 Gbps. Going back to the compatibility of Cisco devices, your GLC-LH-SM is designed to work with the Express 500, 2940, 2948G, 2950, 2960, 2970, 3560, 3560E, 3750, 3750E, 4500, 6000 and 6500 series. That represents quite a few different devices, including WAN Application Acceleration Bundles, WAN Optimization Bundles, Integrated Services Routers, Branch Office in a Box Bundles, Ethernet Switches, Firewall Editions, Voice Security Bundles and ITP Signaling Gateway Bundles, just to name a few. Finally, this Cisco compatible GLC-LH-SM SFP module manufactured by Gencom does not skip out on the quality it delivers.
