Shockproof packaging box of optical splitter

Abstract

The invention discloses a shockproof packaging box of an optical splitter. The shockproof packaging box of the optical splitter comprises a packaging box body. An optical fiber coil-in hole is formed in the right end surface of the packaging box body, and a row of optical fiber coil-out holes are formed in the right end surface of the packaging box body. An optical fiber protector is arranged in the center of the inner surface of the packaging box body. An installation base is arranged on the portion, close to the optical fiber coil-in hole, of the inner surface of the packaging box body. A steel pipe sleeve is installed on the installation base in a supporting mode, and a buffering shockproof layer is arranged between the interior of the steel pipe sleeve and the planar light wave circuit splitter and attached to the inner surface of the steel pipe sleeve closely. According to the shockproof packaging box of the optical splitter, through the improvement of the internal structure of the optical splitter, the optical splitter can conform to 'technical requirements for passive optical splitter of China telecom' when mechanical performance tests of the optical splitter are carried out, and the service life of the optical splitter is prolonged effectively.

Description

technical field [0001] The invention relates to the field of shockproof devices, in particular to a shockproof packaging box for an optical splitter. Background technique [0002] In the optical communication industry, box-type PLC is a widely used passive device. In the production process of box-type PLC (Planar Light wave Circuit Splitter, planar optical waveguide splitter), the bare device PLC is first packaged in a steel pipe , and then package the packaged PLC into a square box. [0003] In the "Technical Requirements for China Telecom Passive Optical Splitter", the mechanical performance requirements of the optical splitter: the box PLC needs to be dropped from a height of 1.8m, 3 axes, 8 times in each axis, 5 cycles, After the fall, the change in IL is less than 0.5dB (dB (Decibel, decibel) is a pure counting unit, which is intended to represent the ratio of two quantities). [0004] In the existing production process, the PLC with the steel pipe is first fixed to ...

AI Technical Summary

Problems solved by technology

[0005] 1. AB glue is mixed by A glue and B glue according to the weight ratio of 1:1. When preparing glue, it is easy to make a wrong ratio and cause the glue to not stick firmly.

[0006] 2. In the process of operation, the optical cable is easy to be glued. Since the AB glue solidifies on the optical cable and cannot be wiped off, the PLC square box is directly scrapped.

[0007] 3. In the traditional process, because the optical fiber is directly coiled in the square box, the bending radius of the optical fiber may be too small or twisted, resulting in unqualified PLC optical performance

Because the AB glue is very hard after curing, if the PLC is defective when sealing the steel pipe or the square box, it was not detected at that time, and it is difficult to repair it later

[0009] 5. In the traditional process, because it is only loosely placed in a square box, the optical fiber shakes in the box during the drop test, causing the optical fiber to be messy, which leads to the PLC optical performance exceeding the standard.

[0010] 6. The AB glue is very hard and brittle after curing. When the cassette PLC is dropped from a height of 1.8 meters, the impact force is very large, causing the steel pipe and the packaging box to fall off. When it falls again, the steel pipe shakes, causing the steel pipe to pull the optical fiber, and finally Cause IL change amount greater than 0.5dB or single fiber break

[0018] Through the patent search, the above patent documents did not disclose the invention, and did not destroy the novelty of the invention
