Problems solved by technology

However, with the increase of the operating life of the optical cable, the performance index of the optical fiber has changed abnormally. Most of the faults occur in the optical cable splicing box on the optical cable, and the water seepage of the optical cable splicing box is the main fault.
[0003] Optical cable splicing boxes are usually mounted on poles and towers in the wilderness. The general optical cable splicing boxes are composed of an outer box and an inner box, forming multiple sealing measures, but the sealing effect will gradually deteriorate with time, and it cannot prevent environmental pollution. entry of water vapor
Due to the extremely low outdoor temperature in winter, if water vapor enters the cable junction box and freezes in the fiber optic box, it will easily squeeze the optical fiber and cause communication interruption, posing a threat to safe production.

Abstract

A waterproof optical cable connection box of the present invention comprises an outer box and an inner box, the inner box is installed in the outer box, and the surfaces of the outer box and the inner box are coated with waterproof paint. A gap of the outer box is provided with a sealing strip, the sealing strip expands after absorbing water, and the surface of the outer box is provided with a window used for observing the interior. The window is provided with an observation plate connected with the outer box in a sealed mode, a drying agent is arranged in the outer box, and the drying agent changes color after absorbing water. The optical cable connection box has better waterproof performance.

Description

【Technical field】 [0001] The invention relates to a waterproof optical cable junction box, which belongs to the technical field of optical cable junction boxes. 【Background technique】 [0002] At present, optical fiber plays an important role in information transmission all over the world. It has many advantages such as anti-interference, large bandwidth, and low cost. Therefore, optical fiber and its related fields have developed rapidly in the past 30 years. Optical fiber splicing is one of the most common and important links in optical cable engineering. The optical fiber splicing process and the selection of optical cable splicing boxes will affect the performance of optical fibers and the service life of optical cables. However, with the increase of the operating life of the optical cable, the performance index of the optical fiber has changed abnormally. Most of the faults occur in the optical cable splicing box on the optical cable, and the water seepage of the optica...
