Product Overview: 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.

E3 OLTE (Optical Line Trasmission Equipment) : Technical Specification

See application diagrams

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, throught TCP/IP Remote Access Server for remote access and monitoring.

E3-OLTE is available in two configurations:

i)   With the option of 1+1 Optical Redundancy (Protection Switching), in which the
     transmission automatically switches to a STANDBY optical link in the event of a failure
     of the PRIMARY optical link.

ii) Without the option of Optical Redundancy (Protection Switching).

External Interfaces:

E3-OLTE unit provides the following interfaces to the external world:

1, 34Mbps, 75 Ohms unbalanced electrical interface

2, 34Mbps, optical interface(s) - only one link is active at a time (optional)

-48V input for E3-OLTE on-board power supply

RS232 interface for connection to Network Management System, used for configuration and monitoring of E3-OLTE system.

2 alarm extensions for visual and audible alarms.

Programming and Monitoring

E3-OLTE offers programming via an RS232 port for control and monitoring of the terminals. Both local and remote terminals can be monitored and controlled using a PC loaded with the NMS software connected to the local terminal.
