Embodiment 1

[0039] The connection method of transition soft joints for single-layer armored and double-layer armored submarine optical cables is as follows:

[0040] 1. Take two sections of submarine optical cable to be connected: single-layer armored submarine optical cable end and double-layer armored submarine optical cable end;

[0041]2. Strip two layers of polypropylene rope (PP rope) from the end of the single-layer armored submarine optical cable, the length is 8.5-10.5 meters, and the length of the stripped steel wire is 2.5-3 meters. The steel wires are divided into 3 groups to protect the steel wires and ensure the pitch No change, the unstripped part is fastened with a throat hoop;

[0042] 3. Strip the inner and outer steel wires of the double-layer armored submarine optical cable end, the length is 1~1.5 meters, and the unstripped part is fastened with a throat hoop;

[0043] 4. Remove asphalt on the single-layer armored submarine optical cable end and the double-layer armo...

Abstract

The invention relates to a monolayer-armored and double-layer-armored submarine optical cable transition soft connector and a connection method thereof. The monolayer-armored and double-layer-armored submarine optical cable transition soft connector and the connection method are suitable for connection of submarine optical cable plants in a submarine optical fiber communication system. The monolayer-armored and double-layer-armored submarine optical cable transition soft connector comprises an optical fiber, a monolayer-armored submarine optical cable stainless steel pipe, outer-sleeved stainless steel pipes, a double-layer-armored submarine optical cable stainless steel pipe, a monolayer-armored submarine optical cable core, a wrapping filling cable core, a double-layer-armored submarine optical cable core, an inner-layer pre-twisting steel wire, a middle-layer pre-twisting steel wire and an outer-layer pre-twisting steel wire, wherein the stainless steel pipe is sleeved outside the optical fiber, the outer-sleeved stainless steel pipes are sleeved on connection-end stainless steel pipes of the monolayer-armored submarine optical cable stainless steel pipe and the double-layer-armored submarine optical cable stainless steel pipe, the wrapping filling cable core is wrapped on the connection-end stainless steel pipes and the outer-sleeved stainless steel pipes, a monolayer-armored submarine optical cable armored stainless steel wire, the inner-layer pre-twisting steel wire, the middle-layer pre-twisting steel wire and the outer-layer pre-twisting steel wire are sequentially twisted outside the wrapping filling cable core, and a polypropylene rope is twisted on the outer-layer pre-twisting steel wire and bonded with the outer-layer pre-twisting steel wire through pitch.

Description

technical field [0001] The present invention relates to a single-layer armored, double-layer armored submarine optical cable transition flexible joint and its connection method, which relates to a connection method between a single-layer armored submarine optical cable and a double-layer armored submarine optical cable, and is suitable for submarine optical cable factories in submarine optical fiber communication systems It is also suitable for the maintenance of submarine optical cable failures. Background technique [0002] There is an urgent demand for transition joint technology and product services in the international and domestic markets. Most customers require large-length supply without joints, and the sea area is different in actual use. The armored structure of the same submarine cable has single-layer armor and double-layer armor. Two types of armor. To realize the continuous large length of this kind of submarine optical cable, there are currently two methods, ...
