Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] Such as figure 1 The longitudinal watertight tightly wraps the optical fiber, including the optical fiber body 1, which is different in that: the optical fiber body 1 is wrapped with a water-proof layer 2, and at the same time, the water-proof layer 2 is wrapped with a tight cladding 3 to achieve effective watertightness sex.

[0027] In conjunction with a preferred embodiment of the present invention, in order to have a better communication effect and meet the needs of ocean exploration, ocean mining, and deep-sea information transmission, the optical fiber body 1 used is a silica optical fiber. From the perspective of implementation optimization , the type of mi...

Abstract

The invention relates to a longitudinal watertight tight-buffered fiber and a preparation method thereof. The longitudinal watertight tight-buffered fiber comprises a fiber body, wherein the fiber body is packaged by a waterproof layer; and the waterproof layer is packaged by a tight-buffering layer. In a preparation period, steps of paying off a fiber, coating a bare fiber, carrying out drying, carrying out extrusion tight-buffering and carrying out cooling are carried out to obtain a finished product. Independent organic silicon gel is taken as an intermediate medium. Bonding and buffering effect between the bare fiber and the tight-buffered layer is realized, and a longitudinal watertight effect is achieved. Integral construction is simple. Preparation is convenient. An application requirement for longitudinal watertight performance of 10MPa and a water depth of 1000m is satisfied.

Description

technical field [0001] The invention relates to a preparation method, in particular to a longitudinal watertight tightly wrapped optical fiber and a preparation method thereof. Background technique [0002] Composite cable is suitable for broadband access network system as a transmission line. It is a new type of access method, which integrates optical fiber and power transmission copper wire, and can solve the problems of broadband access, equipment power consumption, and signal transmission. [0003] However, the existing composite cables are only suitable for use in conventional environments. For laying on the seabed, they often fail to achieve the corresponding compression resistance, and are prone to water leakage and damage. [0004] At the same time, combined with the existing technology patent No. 201711381271.6 a longitudinal watertight cable, patent No. 201720990870.7 a longitudinal watertight cable, patent 201921767088.x a longitudinal watertight cable, patent 201...
