E3 OLTE - Technical Specifications
Valiant VCL, 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.
Available with 1+1 optical protection
(redundancy). The VCL-E3 OLTE is powered by STM-1 grade Class I Laser.
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 Valiant's TCP/IP Remote
Access Server for remote access and monitoring.
