Description

Coated optical fiber performance detection device

Technical Field

The present utility model relates to a detection device, and more particularly, to a coated optical fiber performance detection device.

Background

The current optical cable industry standard divides the tight-buffered optical fiber into three types of I type, II type and III type according to the stripping length and stripping force of the coating layer of the tight-buffered optical fiber, which are respectively corresponding to the commonly-called tight-buffered optical fiber, half-buffered optical fiber and loose-buffered optical fiber, wherein the production of the half-buffered optical fiber is difficult to stably control the tightness, the shrinkage of the loose-buffered optical fiber is generally larger due to the shrinkage of the loose-buffered coating layer, the temperature attenuation performance is generally poorer, so the half-buffered optical fiber and the loose-buffered optical fiber are only suitable for a few scenes with special requirements on the stripping length of the coating layer, and the I-type tight-buffered optical fiber is most widely used. At present, miller pliers are generally adopted to strip tight-buffered optical fibers, and only the stripping performance of the tight-buffered optical fibers can be experienced qualitatively. The accurate stripping force value is generally tested by adopting a universal pulling machine and a special stripping clamp, but the testing cost is high and the period is long. The above is directed to the peeling force index, the tightness is mainly directed to water and gas, it is well known that the optical fiber is afraid of water and moisture, and no specific requirement and test index are currently put on the tightness of the coated optical fiber in the industry, so it becomes necessary to provide a simple visual test device for detecting the tightness and tightness of the coated optical fiber.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.

An embodiment of the present utility model provides a coated optical fiber performance detection apparatus for detecting performance of a coated optical fiber 3 to be detected, as shown in fig. 1, the apparatus may include: a bottle body 1 and an optical fiber holding tube 2.

In an embodiment of the present utility model, the coated optical fiber 3 to be detected may include a tight-buffered optical fiber, a half-tight-buffered optical fiber, and a loose-buffered optical fiber. The properties of the coated optical fiber to be tested may include tightness and tightness.

In the embodiment of the present utility model, an insertion port 101 is opened at the top of the bottle body 1, and the insertion port 102 is used for inserting the optical fiber holding tube 2. The insertion port 102 is a circular opening. In the embodiment of the present utility model, the shape of the bottle body 1 may be set based on actual needs, and preferably, may be set to be square or circular. The bottle 1 may be made of a transparent material. Graduation marks 102 are provided on both sides of the bottle body 1 so as to observe the position of the detection liquid.

In an embodiment of the present utility model, the optical fiber holding tube 2 may include a cylindrical tube body 201 and a stop portion 202 formed to extend outwardly along one end of the tube body, that is, an annular truncated cone formed in the circumferential direction of the tube body. The tube 201 and the stopper 202 may be integrally formed. The fiber holding tube may be made of a transparent material, and in one exemplary embodiment, may be made of an acrylic material. The inner diameter of the tube 201 may be slightly larger than the outer diameter of the covered optical fiber 3 to be detected, for example, 1mm larger than the outer diameter of the covered optical fiber 3 to be detected. Further, the other end of the tube 201 is formed with an opening 203.

Wherein, when the optical fiber holding tube 2 is connected with the bottle body 1, the stop part 202 is connected with the top of the bottle body 1, i.e. is placed on the top of the bottle body 1, and the tube body 201 is inserted into the bottle body 1 through the insertion opening 101 and is spaced from the bottom of the bottle body 1 by a preset distance. The preset distance can be set according to actual needs and can be a self-defined value as long as the preset distance can be spaced from the bottle body.

In the embodiment of the present utility model, the interior of the bottle body 1 is used for accommodating the detection liquid 4, the color of the detection liquid 4 is different from the color of the coated optical fiber 3 to be detected, and the height of the detection liquid 4 is greater than the preset distance. In one exemplary embodiment, the detection liquid 4 may be color ink. The height of the detection liquid 4 may be set based on actual needs, in an exemplary embodiment the distance between the level 401 of the detection liquid 4 and the opening 203 is larger than 60mm.

Since coated optical fibers conventionally have 12 colors including blue, orange, green, brown, gray, white, red, black, yellow, violet, pink, cyan, and 1 transparent color, the color of the color ink cannot be the same as that of the coated optical fibers. For the convenience of observation, the red coated optical fiber is preferably made of blue ink, and the other colors are preferably made of red ink.

Further, in the embodiment of the present utility model, one end of the coated optical fiber 3 to be detected is flush with the opening 203 of the tube body, i.e., on the same horizontal plane, and the other end protrudes out of the tube body and is fixedly connected with the tube body, so as to ensure that the coated optical fiber to be detected is located in the tube body in a vertical manner. In a practical application scenario, the end of the coated optical fiber 3 to be detected is cut flat to ensure that it is flush with the opening 203. In an exemplary embodiment, the coated optical fiber to be tested may be attached to the tube 201 by bonding. In another exemplary embodiment, the coated optical fiber 3 to be inspected is connected to the tube 201 by a clamp (not shown).

When the detection device provided by the utility model is practically applied, the performance of the detection device can be judged by observing the length of the color ink permeated into the bottom of the coated optical fiber to be detected. The specific length of the color ink permeated into the bottom of the coated optical fiber to be detected can be obtained based on a test experiment, and in an exemplary embodiment, when the distance between the liquid level 401 of the detection liquid and the opening 203 is greater than 60mm, after the coated optical fiber is placed in the detection device for 1min, if the length of the color ink permeated into the bottom of the coated optical fiber to be detected does not exceed 5mm, the optical fiber is in a tight package state, and the tightness is good. If the penetration length exceeds 5mm, it means that the fiber is poor in tightness and tightness.

The detection device provided by the embodiment of the utility model can intuitively see the tightness and tightness of the coated optical fiber through the length of the penetration length, is simple and convenient, and has good visualization effect.

Those skilled in the art will recognize that if the greater the distance between the liquid level 401 of the detection liquid and the opening 203, the greater the ink pressure at the bottom of the coated optical fiber can be obtained according to the liquid pressure calculation formula p=ρ×g×h, the greater the reference of the length of the color ink permeated into the bottom of the coated optical fiber to be detected for judging the performance is.

While certain specific embodiments of the utility model have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the utility model. Those skilled in the art will also appreciate that many modifications may be made to the embodiments without departing from the scope and spirit of the utility model.
