<p>PURPOSE:To wire a jamper wire such that transmission loss of an optical fiber incorporating the jamper wire does not increase nor the function thereof degrades by changing the height of vertical face section and the lateral direction. CONSTITUTION:Bolt holes 11, 11 are made at the upper section of the vertical face section 6 of a bracket 5, and many bolt holes 12, 12 are also made with same pitch through a supporting plate 7. A row of many bolt holes 13 are made laterally, with proper interval, through the upper section of the supporting plate 7. In a clamp metal fixing metal 8, a threaded shaft 9 is projected upward from the center of the fixing seat 15. In a jamper wire clamp metal 10, a stopper metal 18 is fixed by a shaft 17 rotatably in vertical direction and it is tightened by means of a bolt 20 in a notched groove 19 and a nut 21. By such arrangement, height, lateral direction and orientation can be changed, excessive stress is not produced in the jamper wire, transmission loss of optical fiber cable does not increase and malfunction can be prevented.</p> |
