The ENET 3CGBIC97-ENC 3Com® Compatible GBIC transceiver operates at 1000BASE-ZX with a wavelength of 1550nm with a maximum reach of 80km. Each is 100% compatible tested 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 3CGBIC97-ENC is individually programmed in-house and then Spirent® tested for performance and functionality as well as compatibility tested in target 3Com® platforms. Old and new revisions of 3Com® operating software are used for testing to ensure 100% compatibility. ENET tests each transceiver using Spirent® Test Centers to emulate live traffic through actual reels of fiber ranging in lengths from 100 meters to over 100 kilometers. These extensive performance testing procedures combined with compatibility testing in more than 80 switches, routers, and servers guarantees each and every transceiver performs flawlessly in its intended environment. All ENET 3Com® compatible transceivers are MSA compliant for seamless integration and RoHS compliant for environmental conformity. All ENET transceivers are backed by a Lifetime Replacement Warranty.
