Problems solved by technology

[0005] The purpose of the present invention is: to overcome the difficulty that the optical contact surface of the optical connection device needs to work in the air in the towed linear array filled with light wax oil under a certain pressure, and propose a method to solve the problem of optical fiber through physical isolation. Radial sealing prevents the infiltration of light wax oil along the outer jacket of the optical fiber and between the coating layer, thus providing a method for radially sealing the optical fiber in the digital optical transmission towed line array

Embodiment 1

[0032] The method of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0033] Referring to Fig. 1-6, Fig. 1-6 is also a flow chart of the production method of the present invention, and the specific steps include:

[0034] 1) Select an ordinary single-mode optical fiber with a length of 500 mm and a diameter of 0.9 mm, with an MTRJ optical connector 4 at one end, and its outer sheath 3 is made of plastic. Wipe the single-core bare fiber 2 with the coating layer 1 clean with absorbent cotton with anhydrous industrial alcohol;

[0035] 2) The polyurethane tube with a cutting length of 50 mm is the first oil-resistant casing 5, and the polyurethane tube with a cutting length of 420 mm is the second oil-resistant casing 10;

[0036] 3) Take the sealing cover 7 and the inner wall of the sealing tank 8 and wipe them clean with absorbent cotton dipped in industrial alcohol or acetone, put the first oil-resistant sleeve 5 on t...

Abstract

The invention relates to optical fiber radial seal method of digital light communication daggle wire array, in the method the oversheath of optical fiber is removed, cleaning process, and the naked fiber is clean up for standby; two oil-proof cannulas for optical fiber cover the naked fibers, and get a sealed cap and naked wire through the sealed cap from the end without optical connector, and the first oil-proof cannula enters the sealed cap; and get the second oil-proof cannula to connect with the other end of optical connector, on end of the second oil-proof cannula also enters the sealed cap, and fill with sealed material to do necessary protection, the radial seal of optical fiber can be realized by filling the sealed material between the optical fiber and sealed cap, and it can avoid the liquid to pollute the light contacting surface and effect the light transmission.

Description

technical field [0001] The invention relates to the technical field of towed line arrays, in particular to a method for radially sealing optical fibers in digitalized optical transmission towed line arrays filled with light wax oil under certain pressure. Background technique [0002] From the perspective of data transmission medium, the development of towed line array has gone through the process of analog data wire transmission to digital coaxial cable data transmission and then to digital optical fiber data transmission. [0003] The towed line array is an array sensing system, which picks up the sound field information by multiple sensors, and sends it to the signal processing system after a long-distance transmission of up to one kilometer. The early towed line array adopts the method of analog data wire transmission, that is, each signal is transmitted by an independent wire. Due to the limitation of the size of the tow cable, the number of cable cores used for long-di...
