Fiber optic connection components for fiber to the home

Abstract

The invention discloses an optical fiber connecting assembly for fiber to the home, which comprises the following components: a fan-out device, a multi-core main optical cable with one end introduced into the fan-out device, a multi-core optical fiber connector with the other end extending out from the fan-out device and connected with the multi-core optical fiber connector outside the fan-out device, a plurality of single-core distribution optical fibers with one ends introduced into the fan-out device and connected with a plurality of bare optical fibers of the main-core main optical cable, and a plurality of single-core optical fiber connectors with other ends extending from the fan-out device and connected with the plurality of the single-core optical fiber connectors outside the fan-out device. The size of the fan-out device provided by the invention is remarkably smaller than that of an optical fiber joint box in which an optical fiber connector and an adapter are configured. Furthermore, the extending-out length of the single-core distribution optical cable from the fan-out device can be freely configured according to the actual application state according to the invention, thereby improving convenience in use.

Description

technical field [0001] The invention relates to an optical fiber connection assembly for optical fiber to the home. Background technique [0002] In the existing fiber-to-the-home technology, an optical fiber splice box is generally used to realize the connection between the multi-core main optical cable and the single-core user optical cable at the user end. For example, figure 1 A schematic perspective view of an existing optical fiber splice closure 10 is shown, figure 2 show figure 1 is a schematic diagram of the optical fiber splice closure 10 after the cover 14 is removed. [0003] Such as figure 1 and figure 2 As shown, the optical fiber splice closure 10 mainly includes a box body 12 and a box cover 14 . A multi-core main optical cable 16 including multiple optical fibers is introduced into the housing 12 from one end of the optical fiber splice closure 10 . On the rear side of the case, a plurality of fiber optic adapters 18 including an internal port insid...

Problems solved by technology

[0005] like figure 1 and figure 2 As shown, because the optical fiber splice closure 10 needs to arrange all the optical fiber connectors 13 and the optical fiber adapters 18 in the box body 12, therefore, the size of the entire optical fiber splice closure 10 is very large, and when the installation space is small, especially in the When used downhole, it will have a great impact on the use, and the manufacturing cost of the optical fiber splice box 10 is also very high

[0006] in addition, figure 1 and figure 2 The adapter 18 of the shown optical fiber splice closure 10 is fixed on the box body 12, therefore, the single-core user optical cable at the user end must have sufficient length so that it can be connected to the adapter 18, once the length of the single-core user optical cable at the user end is not enough , it must be replaced, which also brings inconvenience to the application
