introduction:model3012, 101001000mbps adaptive gigabit ethernet fiber converter uses the switching technology to conduct media conversion, which meets the standards of ieee802.3, ieee802.3u, ieee802.3z and ieee802.3ab. this kind of media converter supports two types of media network connections: 10base-t100base-tx1000base-t and 1000base-sxlx. model3012 can conduct mutual conversion between 10base-t100base-tx1000base-t twisted pair electrical signals and 1000base-sxlx optical signals. this media converter extends the transmission distance of a network from 100m over copper wires to 20 km. this media converter supports transmission in dual-fiber multi-mode, dual-fiber single-mode, single-fiber single-mode, scstfc style fiber-optic connections.features:1. accord to ieee802.1 10base-t, ieee802.3u 100base-tx, ieee802.3ab 1000base-tx, ieee802.3z 1000base-sxlx2. mdimdi-x auto negotiation, 10m100m1000m auto negotiation3. supports full half duplex, point-to-point transparent transfer4. power external 5vdc input5. plug-and-play, easy to installation6. can insert to 2u 19", 14 slots rackmountspecification:standards: comply with ieee802.1 10base-t, ieee802.3u 100base-tx, ieee 802.3ab 1000base-tx, ieee802.3z 1000base-sxlx standardsrj45 port rate: 101001000mbps auto negotiationoptic port rate: 1000mbps working: asynchronous, point to point, fullhalf duplextransfer distance: rj45port: 1000mfiber optic:20, 40, 60, 80, 100, 120km(sm), 550m(mm) optionalrj45 port cable: utp 5e fiber connector: sc, st, fc optionalfiber optic cables: single mode:8.3125, 8.7125, 9125 or 10125 ummuti-mode:50125, 62.5125 umwavelength:850nm, 1310nm, 1550nm powerpower supply: external 5vdc inputconsumption: 4wenvironmentoperating temp:-20c to 75coperating humidity: 5% to 95%(no condensation)warranty: 5 yearsapprovals: fcc, c
