COMMUNICATION SYSTEM OF FAR INFRARED RAY REGION AND ITS COMMUNICATION LINE

摘要

PURPOSE:To enable to obtain the performance having the passage region at far infrared ray region, by selecting the ratio of diffractive rate and the diameter of the clad type of quartz fiber cable. CONSTITUTION:The quartz fiber cable is constituted with the concentric double layer of the clad covering the center and with the center itself, which has the transmission mode determined with the ratio of the diffractive rate and the diameter of the both. Accordingly, by selecting the diffractive ratio and the diameter, the performance having the passage region at the far infrared ray region can be obtained.
