Ethernet converter FO-4E1T1

fiber opticuniversalrack

This 4E1 or 4 T1 multiplexer over redundant 1+1 optical fibers (with SFP) is combining together TDM links carrying 4 E1 or T1 payloads, and next generation Ethernet traffic. The FO 4E1T1 can be used by Telcos for 2G/3G/4G transport, in utilities and transportation infrastructures, or in enterprise campus environments to carry voice and Ethernet traffic. This fiber optic modem transparently transports 4 clear channel E1 G703 or T1 with their fully independent clocks. It is particularly useful when interconnecting PBXs and enterprise LANs, connecting mobile BTS to MSC, or extending interfaces from PDH/SDH nodes. The FO-4E1T1-2TTX has two redundant interfaces to provide for full 1+1 protection. These interfaces use a large range of standardly available SFP modules, covering distances from 2km to 200km, or with single WDM fiber (1310/1550nm) or colored CWDM fiber to multiplex with other optical links. The FO-4 E1T1-2TTX is provided with two Ethernet 10/100BT interfaces to carry Ethernet / IP payload traffic, and provides full administration duties utilizing TCP-IP and SNMP. The Ethernet data is carried in IEEE802.1D bridging mode with QoS based on DSCP of IP frames. Telcos are using the FO-4 E1T1-2TTX to connect 2G/3G BTS over a single fiber for payload traffic, together with the added ability to provide for equipment administration via Ethernet. The FO-4E1T1-2TTX is available in desktop versions, AC or DC48v / 24v, or in rack card for AMS4 or AMS16 chassis ,with SNMP management. The RACK-2-UNIVERSAL can fit two modems in a standard 19" rack.
