Hatteras Networks has integrated a Time-Domain Reflectometer (TDR) into its Mid-Band Ethernet platforms, enabling carriers to accurately perform loop prequalification, and to monitor/maintain selected network facilities throughout the life of their deployment. These critical activities can be performed from either the central office or from a remote location via a web interface.
Hatteras Networks said its new TDR solution performs two critical tasks that save carriers from losing unnecessary time and money. The first, loop prequalification, is a one-time operation that involves the testing of a copper pair to determine the suitability for, and expected performance of, the intended service. Loop prequalification includes detection of flaws in the underlying copper infrastructure as well as accurate measurement of loop length. The second operation, loop troubleshooting, is an ongoing activity. This function finds and characterizes problems with previously qualified copper pairs. Loop troubleshooting detects any post-deployment cable damage or cable degradation.
