Abstract
The utility model discloses an optic fibre macrobend detects tester, tester include base and support frame, and support frame one side is equipped with movable rocker, hold -in range driving wheel and hold -in range take -up pulley, and the opposite side is equipped with slide bar and the ball screw who links to each other with the hold -in range driving wheel, and the activity rocker is connected with the wheel, and the wheel is equipped with the bearing with the support frame junction, is equipped with the internal thread slider on the slide bar, the utility model discloses use slider, slide bar and ball screw's combination, enable the loose winding of optic fibre, evenly distributed zero lap for the optic fibre macrobend detects, and convenient light and handy, it is convenient to use.
Description
Technical field
The utility model relates to a kind of optical fiber macrobend and detects tester.
Background technology
Optical fiber uses more and more general, bendingly causes radiation loss to optical fiber, and when optical fiber is subject to very large bending of radius, when bending radius and its core diameter have comparability, its transport property can change.A large amount of guided modeses is converted to radiation mode, no longer continues transmission, but enters the coated layer of covering or covering absorption, thus causes the added losses of optical fiber.
The added losses that many bending (macrobend) that the radius-of-curvature of macrobending loss optical fiber is larger than fibre diameter causes, main cause has: route is turned and bending in laying; Various reserved bending (reserved circle, the natural torsion) caused of optical fiber cable; In connector box the dish of optical fiber stay, the coiling etc. of tail optical fiber in machine room and equipment.
According to ITU-TG652 regulation, single-mode fiber test macrobending loss method, adopt diameter 60mm pine around 100 circles, additional attenuation is less than 0.5dB/Km.
Utility model content
The utility model provides a kind of optical fiber macrobend to detect tester.
The technical solution adopted in the utility model is:
Optical fiber macrobend detects tester, described tester comprises base and bracing frame, support frame as described above side is provided with movable rocking bar, Timing Belt driving wheel and Timing Belt stretching pulley, opposite side is provided with the slide bar and ball screw that are connected with Timing Belt driving wheel, described movable rocking bar is connected with wheel, described wheel and bracing frame junction are provided with bearing, and described slide bar is provided with internal thread slide block.
The utility model has the advantages that: the combination using slide block, slide bar and ball screw, can make the loose winding of optical fiber, be uniformly distributed zero lap, detect for optical fiber macrobend, convenient light and handy, easy to use.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model.
Wherein: 1, movable rocking bar; 2, bearing; 3, Timing Belt driving wheel; 4, internal thread slide block; 5, base; 6, bracing frame; 7, slide bar; 8, ball screw; 9, Timing Belt stretching pulley; 10, wheel.
