Submarine optical cable and equipment for submarine optical cable water seepage test

Abstract

The invention provides equipment for a submarine optical cable water seepage test, and provides a submarine optical cable and equipment for the submarine optical cable water seepage test. The equipment comprises a test container with one end provided with a through hole for an optical cable to pass through, a base arranged on the outer side of the test container and used for fixing the first end of the submarine optical cable, a connecting piece with a first part abutting against the first end of the base and a second part penetrating through the second end of the base and fixed to the test container, and a sealing piece clamped between the base and the test container and arranged on the outer side of the through hole in a sleeving manner. According to the equipment for the submarine optical cable water seepage test, water in the test container can be prevented from seeping from the position between the base and the test container when the water pressure in the test container is increased, it is guaranteed that the test is conducted smoothly, and the accuracy of the test is better improved.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to a submarine optical cable and equipment used for a water seepage test of the submarine optical cable. Background technique [0002] Submarine optical cable, also known as submarine communication cable, is a wire wrapped with insulating material and laid on the seabed to establish telecommunication transmission between countries. Among them, the submarine optical cable water seepage test aims to simulate the situation of water seepage caused by the seawater pressure of the submarine cable and the stainless steel tube optical unit core after the optical cable is accidentally damaged in the submarine environment. According to the requirements of the industry standard, it is necessary to maintain the corresponding pressure according to the operating water depth of the submarine cable, and continue the constant pressure test for 14 days. After that, the submarine cable is taken...
