Optical fiber splitter with good moisture resistance and use method thereof

Abstract

The invention discloses an optical fiber splitter with good moisture resistance and a use method thereof.The device comprises a splitter box, a box door is arranged at one end of the splitter box, a fixing frame is fixed to the middle of the inner wall of the top of the splitter box, a plurality of splitting devices are fixed to the fixing frame in a penetrating mode, and a wire arranging net frame is arranged at the bottom of the fixing frame; connecting cavities are formed in the top end and the bottom end of the box door, and connecting pieces are slidably connected to the two sides of the inner wall of each connecting cavity; the method comprises the following steps: overhauling devices and circuits by opening the box door, closing the box door at one end of the shunt box along the extension blocks at the four corners after the overhauling is finished, and enabling the sealing pieces at the top and the bottom of the box door to slide into the space between the two contact pieces. According to the invention, the connection pad is tightly pressed on the side wall through reverse force application, so that the sealing performance between the box door and the splitter box is improved, and the moistureproof effect of the interior of the splitter box is enhanced by fully utilizing the cooperation of a fixing mode and a sealing mode.

Description

technical field [0001] The invention relates to the technical field of optical fiber splitters, in particular to an optical fiber splitter with good moisture resistance and a use method thereof. Background technique [0002] Optical fiber splitter is a device used to realize the splitting and combining of light wave energy. It distributes the light energy transmitted in one optical fiber to two or more optical fibers according to a predetermined ratio, or transmits the optical energy in multiple optical fibers. The optical energy of the optical fiber is synthesized into one optical fiber. When the optical fiber splitter is used in the process of optical fiber signal transmission, in actual use, multiple optical fiber splitters installed in the box are often installed at the corresponding position of the optical fiber transmission. [0003] In the prior art, an optical fiber splitter box is generally installed at a corresponding position outdoors, and a plurality of optical f...

Problems solved by technology

[0003] In the prior art, an optical fiber splitter box is generally installed at a corresponding position outdoors, and a plurality of optical fiber splitters and corresponding optical fiber cables are arranged in the box, and the devices and cables are connected in the box for signal splitting. road or transmission, and requires staff to check or repair during long-term use. Generally, the optical fiber splitter box is used with a door on the front of the box and a cover on the back, but it is often only used through Snap-on lock or bolt connection, the sealing and moisture-proof performance of the inside of the box are not enough, which will cause a lot of dust and water vapor to enter the inside of the box during long-term use and increase the possibility of damage to internal components performance, which will affect the effectiveness of the long-term use of fiber optic splitters
