Abstract

The invention relates to an online test unit for an optical main distribution frame (OMDF) on account of centralized optical measurement, which is characterized in that an optical terminal unit of a built-in wavelength division multiplexing (WDM) assembly is additionally inserted into an optical distribution frame (ODF) or the OMDF; an optical cable between optical line terminal (OLT) equipment and an optical distribution network (ODN) is arranged and connected to the optical terminal unit; the patch cord of the OLT on the original ODF/OMDF is removed; the patch cord of the OLT and the patch cord of a centralized optical measurement system are connected to an optical terminal combiner unit; and the test unit is designed into a vertical 6-core plug board or a horizontal 12-core plug board according to different OMDF stands. The online test unit for the OMDF on account of the centralized optical measurement has the advantages that a module with an optical online monitoring function is realized on the ODF/OMDF; through installing a combiner assembly in the optical terminal unit of the ODF/OMDF, an online monitoring function of a passive optical network (PON) can also be provided without interrupting services, thereby, the space of a machine room is reduced to the maximum degree and the consumption of an optical material is saved, and simultaneously, the maintenance management and operation requirements of the ODF/OMDF of a telecommunication machine room are also met.

Description

technical field [0001] The invention relates to an OMDF on-line test unit for centralized termination of equipment optical cables and outdoor optical cables, connection scheduling and centralized optical measurement functions, and belongs to the technical field of measurement of optical fiber distribution frames. Background technique [0002] The optical fiber main distribution frame (OMDF) is an extremely important part of the optical access network. The appearance and use of the optical main distribution frame are inseparable from the large-scale use of the optical access network. Due to the large-scale use of optical cables, the original leather wires or twisted pairs will be gradually replaced by optical fibers, followed by a large number of optical cables that need to be terminated in the office. The way of the transmission room is not conducive to the maintenance of a large number of optical cables and the construction of the optical access network. Therefore, many op...
