Portable instrument for measuring optical signal power, has detectors connected between connectors for propagating one of the bi-directional optical signals to one of the optical network terminals

摘要

The instrument has connectors (22,24) for connecting instrument into an optical transmission path. The detectors (38,42,44) connected between connectors, for propagating one of bi-directional optical signals towards one of optical network terminals. The parameters of propagating optical signals are measured. An independent claim is included for method of measuring parameters of optical signals.
