Paper Abstract

The presence of transient high-order-mode losses in multi-mode fiber optic cable test samples makes accurate data extrapolation to system lengths difficult. Extensive research has resulted in several methods for launching an equilibrium modal distribution (EMD) into the test sample. Most approaches require coupling the launching apparatus to the sample via a fiber optic splice. However, in many cases, splices disturb the modal distribution thereby reducing the effectiveness of the EMD launcher. In these instances, it is valuable to be able to determine the severity of EMD disruption and correct the problem. A technique employing an OTDR in conjunction with a throughput loss measurement system has recently been developed. The system is used to monitor the quality of EMD transfer into a cable sample prior to testing. Test results illustrating the effectiveness of the integrated system are included.
