VCL-E3 OLTE - 34Mbps Optical Line Transmission Equipment
The VCL-E3 & E1-OLTE is a 34Mbps & 2.048Mbps Optical Line Transmission Equipment which converts and transports a ITU-T compliant standard E3, 34Mbps signal and E1, & 2.048Mbps on optical fiber. The optical link, between two OLTE terminals is established on one pair of optical fibers. 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).
Features and Highlights:
- Single - card implementation
- Standard CCITT (ITU-T) compliant interfaces
- Operate on nominal 48V DC input and 220V AC, 50Hz Mains
- Distributed on-board power supply
- Microprocessor controlled with powerful diagnostic facilities for both remote and local systems
- Highly reliable and compact.
Programming and Monitoring:
VCL-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.
Alarm Status Monitoring:
- Loss of electrical signal at 34 Mbps port
- Loss of electrical signal at 2 Mbps port
- System Active
- Loss of optical signal
- Loss of auxiliary frame signal
- Bit error rate out of limit.
External Interfaces:
VCL-OLTE unit provides the following interfaces to the external world:
- 2 x 34Mbps, 75 Ohms unbalanced electrical interface
- 2 x 34Mbps, optical interface
- 2 x 2.048Mbps, 120 Ohms balanced electrical interface
- 2 x 2.048Mbps, optical interface
- 48V DC and 220V AC, 50 Hz Mains inputs for VCL-OLTE on-board power supply
- RS232 interface for connection to Network Management System, used for configuration and monitoring of VCL-OLTE system.
