FO-E3T3 - Fiber Optic Modem G703 E3 34Mbps & T3/DS3 45Mbps

FO-E3T3-TTX - Ethernet bridge 34/45Mbps to Optic Modem G703 E3/DS3

The FO-E3T3 extends G703 E3 or T3/DS3 line over 4 km with multimode fiber optic and up to 100km with single mode fiber. It is very convenient to extend a 34/45Mbps connection over fiber instead of coax cable, and in addition to extend TDM/PDH traffic over fiber at a lower cost than a SDH/SONET installation. The FO-E3T3 provides transparently the transport of the E3/T3 with data and framing (PDH, ATM, etc.).

The FO-E3T3 is used frequently to extend access from a multiplexer/DACS to a microwave radio or router. Some ISPs provide Internet access from a TDM/SDH backbone when they are leasing E3 or DS3 access for large sites. The FO-E3T3 is a plug and play solution between TDM switchs and routers located in the customer premise.

This modem contains two user interfaces: a copper E3/T3-DS3 and an Ethernet bridge. Which is an FO-E3T3-TTX. The modem will be used as an Ethernet Bridge on the CE side and convert to fiber over the WAN. The transport of WAN-HDLC is processing at G703 E3 or T3 format. At the other end of the fiber we can use the FO-E3T3 in Ethernet bridge mode or have it converted to E3/DS3 fiber/copper mode. In this last case the Ethernet WAN traffic is transported over clear channel E3 or T3/DS3 over TDM-PDH or SDH network. The end of the Ethernet link can be terminated by a couple of FO-E3T3 or an electric G703 CV-E3T3-TTX converter. This is an economic way to provide point-to-point Ethernet over TDM network at 34Mbps or 45Mbps.

The FO-E3T3 is very simple to install. Loop tests, BER tests, and statistic are available from the Ethernet consol port in Telnet or with a Windows GUI.

The FO-E3T3 is delivered in compact metallic box or as a card for 19’’ chassis for 4 or 16 cards. Both are available with AC or DC power supply.
