Insertion piece with stable performance and optical splitter

Abstract

The invention discloses an insertion piece with stable performance, which comprises an adapter, a ceramic sleeve, a stabilizing device and a ceramic insertion core. The ceramic insertion core is sleeved in the stabilizing device; one end part of the ceramic ferrule is sleeved in the ceramic bushing, and one end, which is not sleeved with the ceramic ferrule, of the ceramic bushing is mounted in the adapter; a plurality of convex parts are distributed on the surface of the stabilizing device; the stabilizing device comprises one of a limiting ring or a limiting block; the optical splitter disclosed by the invention is provided with the insertion piece, the adapter is arranged in the insertion piece box, and the ceramic sleeve is arranged in the separation blade groove of the separation blade; a fixing hole is formed in one end of the insert box; and the baffle plate is arranged at the end part in the insert box. The stabilizing device is additionally arranged on the ceramic bushing, so that the ceramic bushing can be prevented from sliding, and instability of insertion loss (IL) and return loss (RL) is avoided; and the performance stability is obviously improved.

Description

technical field [0001] The invention relates to a component of an optical splitter, in particular to an insertion piece and an optical splitter with stable performance. Background technique [0002] An optical splitter, also known as an optical splitter, is one of the important passive components in an optical fiber link. It is an optical fiber junction device with multiple input ports and multiple output ports. According to the light splitting principle, the optical splitter can be divided into two types: fusion tapered type and planar waveguide type (PLC type). Insert type optical splitter is a common optical splitter. [0003] At present, the plug-in optical splitter, especially the plug-in, generally adopts several methods such as bar positioning, snap-in positioning, and simple connector type. The bar positioning type is to insert the ceramic sleeve into the ferrule and push In the special adapter, the end of the ferrule is blocked by a bar, but the ceramic sleeve bar...

Problems solved by technology

[0003] At present, the plug-in optical splitter, especially the plug-in, generally adopts several methods such as bar positioning, snap-in positioning, and simple connector type. The bar positioning type is to insert the ceramic sleeve into the ferrule and push In the special adapter, the end of the ferrule is blocked by a bar, but the ceramic sleeve bar is prone to side slip, which causes inaccurate positioning of the other side during docking, resulting in instability of the IL / RL; the snap-in positioning type uses ceramic After the sleeve is inserted into the ferrule, push it into the special adapter, and make the buckle behind the adapter catch the tail of the ferrule. However, the ceramic sleeve rail is prone to side slip, causing the other side to be inaccurately positioned during docking, resulting in IL / RL is unstable, and the ceramic sleeve is easily damaged during assembly; the simple connector type is to assemble the ferrule into the simple connector and then push it into the ordinary adapter, but the simple connector is inconvenient to assemble, and there is a poor connection with the docking adapter Possibly, prone to unstable performance problems
