E3, OLTE (Optical Line Transmission Equipment)

Technical Specifications

Aries Telecom offers the E3-OLTE is a 34Mbps Optical Line Transmission Equipment which converts and transports a ITU-T G.703 compliant standard electrical E3, 34Mbps signal into a G.823 and G.821 compliant optical signal for transport over 1310nm optical fiber cable. The optical link, between two OLTE terminals is established on one pair of optical fiber. One fiber link is used for transmit and the other fiber link is used for receive.


A complete optical line transmission system comprises of two OLTE terminals one at each end of the optical fiber cable. The E3, 34Mbps OLTE also offers 1+1 optical protection (optical redundancy).

Both the Local and the Remote terminals can be monitored and controlled by a Windows based GUI (Graphical User Interface), from a single location. TCP-IP option for remote access is also available.
