OPTICAL CORD

摘要

PURPOSE: An optical cord appropriately adjusts the curl inside diameter. The optical loss can be minimized in extension. CONSTITUTION: It inserts the optical fiber(22) into tight buffers(24, 34) and it mounts the seal reinforcement and the first code(20) covers with cladding. A second code(30) which does not mount the optical fiber is side by side welded with the first code. The curl having the regular length in the length direction middle part of the first and the second code and inside diameter is applied to and the force of restitution is intensification made.
