GTT 120FE Network Optical Terminal
1. Overview
GTT 120FE network optical terminal is the optical access system integrated broadbａnd IP (internet), E1, V35 transmission launched by our company, integrated optical transceiver, PDH optical transmission system and V35 function. The system adopt TDM technology, mix the Ethernet, E1 and V35 signal encoded and transmitting through a couple of optical fiber or single fiber, guarantee the real-time transmission of 10/100/1000M Ethernet service line-rate double duplex and E1 service. Apply to telecom operator in 3G base station, bank, commercial group user, college etc to realize integrated transmission of LAN and PABX or UMTS base station access etc, and has several types of equipments to choose according to the demａnd of bandwidth.
2. Performance feature
Realize broadbａnd IP and E1 access, perfect combination of optical terminal and optical transceiver;
Provide 3 E1 ports, and 4 routes shareable 100M Ethernet interface, support Ethernet switching function, 1 V35 interface;
Ethernet port provide 10/100M self-adapting line-rate full-duplex mode, support IEEE802.1Q VLAN unvarnished transmission;
V35 interface rate is N×64K (N≦32);
To radial network, GTT provide centralized network optical terminal local-end type, support SNMP network management, and can effectively manage and control to bandwidth;
