4PortsIsolationOpticlaTransceiver1
1. Overview
GTT GLLAN-4 4 ports isolation optical transceiver use optical wavelength-division multiplex technology on the basis of traditional optical transceiver technology, to complete Ethernet transmission on a couple of optical fiber instead of original 4 couples of optical transceiver. Provide 4 ports physical isolation 10/100M Ethernet interface, save fiber and reduce transit point, and has higher network security.
2. Performance feature
Multiply decrease the quantity of fiber for user, reduce initial capital cost;
Use few of optical fiber, improve the maintenance efficiency;
Few optical interfaces, means save the space at the state of same situation;
Optical interface rate: 1.25G;
Provide 4 physical isolation Ethernet RJ45 interface, support two-stage switching;
Match IEEE802.3 10Base-T 和IEEE802.3u 100Base-TX，100Base-FX standard;
Full/half duplex self-adapting, 10/100Mbps self-adapting;
Jumbo frame adapting (1600 Bytes);
Electrical interface MDI/MDIX automatic recognition;
Optical interface is SC interface (also FC interface selected);
Optical interface can select single fiber or dual fiber, standard configuration transmission distance is dual-fiber 20KM, single-fiber 20KM, maximum transmission distance 80KM.
3. Physical characteristic
Adopt module power supply: AC220V and DC-48V dual-power, power consumption <10W
Width × depth × height = 220MM ×156MM × 33MM
Working temperature: 5℃-40℃; storage temperature: -20℃-70℃; relative humidity: <95% (non-condensing)
