Problems solved by technology

But this method is only limited to multimode fiber. When it is applied to single-mode fiber tow cable assembly, due to the low bending loss resistance of single-mode fiber, it is not possible to reserve too much margin when assembling the fiber to the connector. Otherwise, the optical fiber will accumulate at the head of the trailer, resulting in excessive bending loss, serious signal attenuation, and inability to effectively transmit the signal

Embodiment 1

[0023] see Figure 1 to Figure 3 , an assembly method of a single-mode optical fiber tow cable connector in this embodiment, the connection between the tow head and the tow cable is realized through the connector, and the following steps are mainly adopted:

[0024] Step 1. Install the tow head on the tow cable to keep a certain distance from the root of the tow cable, so that the optical fiber margin required for later connector assembly can be reserved in advance;

[0025] Step 2. Reserve sufficient margin for the optical fiber and wires to be installed inside the tractor to ensure that the optical fiber is not subjected to tension during work and prevents it from breaking;

[0026] Note that this step is:

[0027] (1) When reserving the allowance of optical fibers and wires, keep the distribution even. The margin is evenly reserved, which can ensure that the optical fibers and wires can be smoothly transferred from the inside of the tow head to the outside of the tow head...

Embodiment 2

[0033] see Figure 1 to Figure 3 , an assembly method of a single-mode optical fiber tow cable connector in this embodiment, the connection between the tow head and the tow cable is realized through the connector, and the following steps are mainly adopted:

[0034] Step 1. Install the tow head on the tow cable to keep a certain distance from the root of the tow cable;

[0035] Step 2. Reserve sufficient allowance for the optical fiber and wires to be installed inside the tractor;

[0036] Different from Example 1, this step should be noted that:

[0037] Optical fibers and wires are evenly arranged inside the drag head in a wave shape. The wavy shape of the optical fiber and wire not only facilitates the installation of the optical fiber and wire in the restricted and narrow space of the tow head, but also facilitates the exposure of the optical fiber and wire when the tow head returns to the root of the tow cable.

[0038] Step 3. Return the tow head to the root of the to...

Abstract

The invention relates to an assembling method of a single-mode optical fiber towing cable connector, and belongs to the technical field of towing cable connectors. The method comprises connecting a towing head and a towing cable through a connector, namely installing the towing head on the towing cable and keeping a certain distance from the root of the towing cable; reserving enough allowance for installing the optical fiber and a wire in the towing head; returning the towing head to the root of the tow cable, and exposing the remaining parts of the optical fiber and the wire outside the tow head; assembling a connector on the exposed optical fiber and the wire; and after the connector is assembled, returning the towing head to the original installation position, and completing whole assembly. According to the assembling method, an effective space can be provided for connector assembling; meanwhile, sufficient optical fiber allowance is uniformly distributed in the towing head, so that the optical fiber cannot be fractured due to stress during working; and the phenomenon that optical fibers are accumulated at the head of the towing head can be effectively solved, so that bending loss and signal attenuation of single-mode optical fibers are effectively reduced, and signals are effectively transmitted.

Description

technical field [0001] The invention relates to an assembly method of a single-mode optical fiber tow cable connector, belonging to the technical field of tow cable connectors. Background technique [0002] As an important branch of sonar, towed sonar can detect underwater targets at different depths by controlling the length of the towline and adjusting the depth of entry into the water. With the requirement of large depth and long-distance combat in the navy, single-mode optical fiber has been widely used in towing systems due to its advantages of long operating distance, large data capacity and low loss of long-distance transmission signals. The towline, as an important part of it, is the only channel connecting the towed sonar to the mother ship, and plays a dual role of carrying loads and transmitting signals. However, due to the low bending loss resistance of single-mode optical fibers, it is necessary to reasonably distribute the length margin of single-mode optical ...
