E3-OLTE is a 34Mbps Optical Line Transmission
Equipment which multiplexes
/ demultiplexes 16, 2Mbps E1 electrical tributaries into a 34Mbps optical stream,
transmitting on a 1310nm (1500nm optional) optical fiber cable to establish an optical
transmission link between locations. The E3, OLTE conforms to all the applicable G.703,
G.823, G.821, G.955, G.652 and G.654 ITU-T (CCITT) recommendations.
Available with 1+1 optical protection
(redundancy). The E3 OLTE is powered by STM-1 grade Class I Laser - by Lucent
Technologies, Inc.
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.
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.
