摘要
The optical distribution network (OSD) comprising a optical splitter DO, single-mode optical fibers and optical fiber cables, fiber optic mechanical connectors and fusion splices an optical path for the optical signals transmitted and received by the optical line termination (OLT) and the optical network unit (ONU 1, ..., n ONUs) while checking the technical state of a specified optical path (fiber optic or fiber optic cable), the optical measuring signal (SP) is suppressed in the macrobending generation device (M). The macrobending generation device (M) is installed on the optical path in which the optical measuring signal (SP) generated in the optical reflectometer (OTDR) is to be attenuated. The corresponding radius of macrobends curvature and their number are selected with this equalizer (K).
