Optical splitter with adjustable splitting ratio, optical fiber splitting box and optical distribution network

Abstract

The application discloses an optical splitter with adjustable splitting ratio, an optical fiber splitting box and an optical distribution network. The beam splitter includes a first structural component, a second structural component and an adjusting component. The first structural part includes a lens and a slot; the second structural part includes two lenses and two slots, and the two lenses are relatively offset in the first direction. The slots are used to accommodate optical fibers. The first structural member or the second structural member is connected with the adjusting member, and when the adjusting member moves, the relative offset between the first structural member and the second structural member in the first direction can be changed, so that the first structural member projects toward the second structural member The ratio of the beam changes. In this application, the splitting ratio of the two paths of light can be adjusted freely only by moving the adjusting member in the splitter, so that it can reach the expected splitting ratio. The beam splitter can meet a variety of different light splitting requirements, and it is not necessary to introduce a variety of different types of beam splitters to split the beam into two, which solves the problem of misuse due to the large number of beam splitter models that are difficult to distinguish.

Description

technical field [0001] The present application relates to the technical field of optical access network, in particular to an optical splitter with adjustable splitting ratio, an optical fiber splitting box and an optical distribution network. Background technique [0002] An optical splitter, also known as an optical splitter, is a passive fiber branching device commonly used in a passive optical network (Passive Optical Network, PON). As a passive device connecting an Optical Line Terminal (OLT) and an Optical Network Unit (ONU), an optical splitter can distribute downlink data to the ONU, and can also centralize uplink data to the OLT. At present, optical splitters can be used in various node products in Optical Distribution Network (ODN), such as Optical Distribution Frame (ODF), Fiber Distribution Terminal (FDT), Fiber Access Terminal (FAT), Closure, etc. [0003] In some application scenarios, ODN needs to use a unequal network including multi-level FAT to realize opt...
