• The changes in fiber strain and fiber loss with temperature are quantitatively evaluated for 0.5mm UV-coated fiber and three kind of fiber-optic access cables, for dropping and indoor wiring, employing 0.5mm UV-coated fiber. Measurements of the fiber strain and loss increase are conducted using a quasi-heterodyne interferometer method and a photon-counting optical-time-domain-reflectmeter, respectively, at 1.3 and 1.55μm. From the strain characteristics, the following observations are made: (a) In the temperature range from -40 to 20℃ the fiber strain followed the cable strain quite closely, thus maintaining a tight cable structure and (b) from 20 to 80℃, the fiber exhibited a lower strain than the cable strain. Furthermore, no loss increase due to temperature change was observed for the 0.5-mm diameter coated fiber and the three type of optical cables.
