CURVED HIGH-SENSITIVITY DETECTION DEVICE FOR BENDING LOSS OF OPTICAL FIBER

摘要

A curved high-sensitivity detection device for bending loss of an optical fiber comprises a curved test channel (4) for a tested optical fiber (1) to pass through and an optical fiber bending loss testing apparatus (5) connected with the tested optical fiber (1). The test channel (4) comprises a test channel outer shell, a plurality of A-side clapboards (4-4) and a plurality of B-side clapboards (4-3), wherein the end of the test channel outer shell correspondingly bends the tested optical fiber (1) under the action of an external stress F; the plurality of A-side clapboards (4-4) and the plurality of B-side clapboards (4-3) are continuously arranged on the two opposite sides in the test channel outer shell. The A-side clapboards (4-4) and the B-side clapboards (4-3) are arranged in a staggering way and a curved channel for the tested optical fiber (1) to pass through is formed between the heads of the A-side clapboards and the B-side clapboards; and the A-side clapboards (4-4) and the B-side clapboards (4-3) are correspondingly arranged on the two sides of the tested optical fiber (1).
