Further, the radius-of-curvature of bending channel is more than or equal to 15 times of the diameter of optical fiber.
Further, reserved optical protective portion is cylindrical curved tube.
Further, the line bar fixture securing member that comprises circular arc anchor ear and coordinate with circular arc anchor ear.
Further, the two ends place of circular arc anchor ear offers through hole, and securing member comprises the bolt suitable with through hole and the nut suitable with bolt.
Further, clamping part inside offers the straight channel can passing optical fiber.
Further, clamping part is cylinder-shaped sleeve.
Further, clamping part is connected with line bar fixture by connecting link.
Application the technical solution of the utility model, is fixedly installed on line bar by line bar fixture, and two optical fiber clamping portions clamp optical fiber and between two optical fiber clamping portions, reserve the corner surplus of optical fiber.Reserved optical protective portion is set on reserved optical fiber.The radius-of-curvature of bending channel can given design according to actual needs, so just can avoid the optical fiber curvature radius reserved too small cause affect the communication quality of optical fiber and affect the problem of fiber lifetime.On the other hand, it is sheathed firmly that reserved optical fiber also can be reserved optical protective portion, avoids optical fiber under the effect of natural cause by line bar friction damage.
Except object described above, feature and advantage, the utility model also has other object, feature and advantage.Below with reference to figure, the utility model is described in further detail.
