The ENET GLC-TE-ENC Cisco Compatible SFP transceiver operates at 10/100/1000 Mbps over Copper Cat5/Cat5e/Cat6 at N/A with a maximum reach of 100 meters. Each GLC-TE-ENC is 100% compatible in fit, form, and functionality compared to the OEM product. Our extensive quality control measures begin with physically inspecting each module, verification of hardware type, wavelength, transmit power, receive power, and full optical monitoring functionality (if applicable). Each GLC-TE-ENC is individually programmed in-house and then Spirent® tested for performance and functionality as well as compatibility tested in target Cisco platforms. Old and new revisions of Cisco operating software are used for testing to ensure 100% compatibility. Our test lab contains Spirent® traffic emulation equipment, along with more than 80 of today''s most popular switches, routers, and servers. All ENET Cisco compatible transceivers are MSA compliant for seamless integration and RoHS compliant for environmental conformity. All ENET transceivers are backed by a Lifetime Replacement Warranty.
