Flexible Detection System Using Portable Remote Fiber Testing System (RFTS) for Damaged Optical Cable Networks

摘要

Nippon Telegraph and Telephone Corporation (NTT) has been constructing optical cable networks for various multimedia services. Maintenance of these networks is obviously important as service increases. We describe a way of recovering optical cable networks after a disaster like the Great Hanshin Earthquake that occurred in Kobe in 1995. This paper details the features of a mini-test equipment module (mini-TEM), a portable remote fiber testing system (RFTS) designed to make testing of optical cable networks more efficient. It describes the functions of a new flexible detection system, its configuration, work flow, and general purpose functions. This system will be introduced in all service areas of NTT.
