Description

Encapsulating sheath for bare fiber of beam splitter

Technical Field

The utility model relates to the technical field of filling and sealing processes of bare fibers of optical splitters, in particular to a filling and sealing sheath of bare fibers of optical splitters.

Background

The optical splitter is a device for splitting and combining optical energy, and distributes the optical energy transmitted in one optical fiber to two or more optical fibers according to a predetermined ratio, or combines the optical energy transmitted in the optical fibers into one optical fiber, and is a passive device, also called an optical splitter, which does not need external energy as long as input light exists.

The traditional box-type beam splitter is manufactured by coiling and placing the bare fiber of the coupling section in the box for protection after coupling and splitting the optical fiber, as shown in fig. 1, the beam splitter box is inconvenient to lay in a narrow environment due to overlarge size.

Disclosure of Invention

Aiming at the technical problems in the prior art, the utility model provides a potting sheath for bare fibers of a beam splitter, which solves the problem that the bare fibers of the traditional beam splitter can only be placed in a beam splitter box for protection after coupling is completed by using the potting sheath.

The technical scheme includes that the anti-corrosion adhesive comprises anti-corrosion adhesive and aramid fiber wires, wherein two ends of each aramid fiber wire are fixedly bound with two ends of each bare fiber, the length of each bare fiber is greater than that of each aramid fiber wire, and the anti-corrosion adhesive is wrapped outside each bare fiber.

Preferably, the anti-corrosion adhesive comprises an inner SQ-1 adhesive layer and an outer SQ-1 adhesive layer, wherein the inner SQ-1 adhesive layer is wrapped outside the bare fiber, and the outer SQ-1 adhesive layer is wrapped outside the inner SQ-1 adhesive layer.

Preferably, the thickness of the inner SQ-1 glue layer is 2mm.

Preferably, the thickness of the outer SQ-1 glue layer is 0.5mm to 1mm.

Preferably, the aramid fiber line is in a straightened state.

Preferably, the connection part of the bare fiber and the connector is coated with QM-1 sealant.

The beneficial effects are that:

1. according to the utility model, through the arrangement of the anti-corrosion adhesive and the aramid fiber, the occupied space when the optical cable is laid can be greatly reduced, the laying and the maintenance are convenient, meanwhile, the vibration resistance and the compression resistance of the bare fiber can be effectively improved, and the tensile resistance of the bare fiber can be improved by combining the arrangement that the length of the bare fiber is longer than that of the aramid fiber.

2. According to the utility model, the vibration resistance and pit pressure capability of the bare fiber can be further improved through the double-layer encapsulation arrangement of the inner SQ-1 adhesive layer and the outer SQ-1 adhesive layer.

3. According to the utility model, the aramid fiber wire is in a straightening state, so that the aramid fiber wire can be ensured to be a direct stressed object in the pulling process.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is evident that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art without making any inventive effort, are intended to be within the scope of the present utility model.

The utility model provides a potting sheath of bare fibers of a light splitter, which is shown in fig. 2 and comprises anti-corrosion glue and an aramid fiber 1, wherein two ends of the aramid fiber 1 are bound and fixed with two ends of the bare fibers 2, the length of the bare fibers 2 is larger than that of the aramid fiber 1, and preferably, the aramid fiber 1 is in a straightened state initially; the method comprises the specific processes of firstly fixing two ends of a bare fiber 2 and an aramid fiber 1 into a first mold to ensure that the aramid fiber 1 is in a straightened state, then carrying out primary filling and sealing, then placing the bare fiber 2 into a second mold after the primary filling and sealing is finished, carrying out secondary filling and sealing, and finally coating QM-1 sealant on the connection part of the bare fiber 2 and a connector.

In this embodiment, through the setting of anticorrosive glue and aramid fiber line 1, can reduce by a wide margin and need occupation space when the optical cable lays, and lay, the maintenance is convenient, also can effectively improve the vibration resistance and the compressive capacity of naked fine 2 simultaneously, specifically because naked fine 2 is softer than traditional extrusion molding sheath after anticorrosive glue embedment, combines the setting that the length of naked fine 2 is greater than the length of aramid fiber line 1, can improve the tensile capacity of naked fine 2.

Finally, it is noted that the above-mentioned embodiments are merely for illustrating the technical solution of the present utility model, and that other modifications and equivalents thereof by those skilled in the art should be included in the scope of the claims of the present utility model without departing from the spirit and scope of the technical solution of the present utility model.
