Optical branching unit and optical branching module thereof

Abstract

An optical branching module comprises a containing groove formed in a bottom shell. The bottom shell is covered with a panel with an opening, the opening is opposite to the containing groove, and the two ends of the panel are provided with installation holes. A transmission optical fiber is formed by multiple optical fibers in a fused biconical taper mode, the end, with one optical fiber, of the transmission optical fiber is a single-fiber end, an the other end of the transmission optical fiber is a multi-fiber end, and the multi-fiber end of the transmission optical fiber is provided with multiple optical fibers. An input end tail fiber is arranged at the single-fiber end and is in communication connection with the single-fiber end. Multiple output end tail fibers are arranged at the multi-fiber end, each output end tail fiber is in communication connection with one optical fiber at the multi-fiber end, and the output end tail fibers are contained in the containing groove. Installation knobs are contained in the installation holes and are used for being connected with external supporting objects. The transmission optical fiber of the optical branching module is of an integrated structure, complication wiring in the optical branching module can be avoided and simplicity of lines of the optical branching module is guaranteed. The invention further provides an optical branching unit.

Description

technical field [0001] The invention relates to an optical splitting device, in particular to an optical splitter and an optical splitting module thereof. Background technique [0002] The optical network system couples, branches, and distributes optical signals, which requires optical branching functional modules to realize. The optical branch function module, also known as the optical splitter, is one of the important passive devices in the optical fiber link. It is a fiber optic junction device with multiple input ports and multiple output ports. M×N is often used to represent an optical branch function. The module has M input terminals and N output terminals, and can be divided into a single-mode optical branch function module and a multi-mode fiber optical branch function module according to the transmission mode. Since each optical splitter has M input ports and N output ports, these optical fibers are connected to each other in the optical splitter, resulting in mess...
