Abstract

The invention relates to an improved optical fiber splice sealing box and a sealing method. The optical fiber splice sealing box is composed of an optical fiber fusion splice tray used for containing and fixing a main optical cable and a plurality of optical fibers, a sealing member used for matching the optical fiber fusion splice tray to fix the main optical cable and the optical fibers, a pressing plate used for fixing the sealing member on the optical fiber fusion splice tray, a square cavity box used for containing the optical fiber fusion splice tray and connected with the pressing plate and the sealing member to form a closed cavity. The optical fiber splice sealing method is as follows: the sealing member fixed with the main optical cable and the optical cables is arranged in a semi-closed cavity on one end of the optical fiber fusion splice tray and is fixedly connected with the optical fiber fusion splice tray through the pressing plate. The optical fiber splice sealing box uses an improved mechanical sealing form and has the advantages of reliable sealing method, simple and convenient operation, repeated use and convenient repair and market expansion.

Description

technical field

[0001] The invention relates to the field of optical communication, in particular to an optical fiber joint sealing box and a sealing method. Background technique

[0002] In the field of optical communication, a main optical cable is usually used to provide optical fiber communication access services to all users in a specific area. Such a main optical cable consists of dozens of single optical fibers, and each optical fiber can provide To provide the same communication service, all designated users in this particular area are distributed in series along the main fiber optic cable.

[0003] In an ideal situation, each optical fiber is stripped from the main optical cable and directly connected to the customer end or optical network unit. But in reality, the main optical cable is continuous, and its length is also determined and cannot be changed arbitrarily. Therefore, it is not feasible to completely strip individual optical fibers at the construction site...
