Optical fiber main distributing frame of MAN (Metropolitan Area Network)

Abstract

The invention relates to an optical fiber main distributing frame of an MAN (Metropolitan Area Network). The optical fiber main distributing frame is characterized by comprising a stand as well as an optical cable fixing and stripping device, a line side module, an equipment side module and fiber jump passages which are arranged on the stand, wherein the optical cable fixing and stripping device is arranged at the left side of the stand, the line side module is arranged to the front of the stand, the equipment side module is arranged at the back of the stand, and the fiber jump passages are respectively arranged in corresponding positions on the stand according to respective actions; the front and the back of the stand are both provided with same side fiber jump passages and spacing-framefiber jump passages; a fore-and-after fiber jump passage is arranged at the right side of the stand; the line side and the equipment side are independently connected through the fore-and-after fiber jump passage; the interior of the line side or the equipment side is independently connected through the same side fiber jump passages; and adjacent stands are independently connected through the spacing-frame fiber jump passages. The invention has the advantages that the independent fiber jump passages are extremely convenient for fiber jumping and can meet the needs of an access network and an MAN for accessing optical fibers and cables.

Description

technical field [0001] The invention relates to an optical fiber main distribution frame used in a communication machine room. The distribution frame is arranged between communication equipment and an optical distribution point, and is mainly used for connecting the communication equipment and the optical distribution point, belonging to the technical field of communication network equipment. Background technique [0002] The traditional optical fiber main distribution frame is mainly used in the access network to realize the connection function between the OLT equipment and the downstream optical distribution point in the FTTH solution, mostly for jumping between the equipment and the line. However, based on the principle that the optical fiber wiring in the future transmission room will adopt centralized dispatching management, the optical cables of the metropolitan area network will also be connected to the optical fiber distribution frame in the future. The metropolitan ...
