Abstract :
Transmission characteristics of coated optical fiber depend on coating materials at low temperature. Loss increase phenomena are compared for UV-curable resin coated and silicone-nylon coated fibers. Different mechanisms induce loss increase depending on coating materials. Lateral forces are caused by shrinkage and Young´s modulus increase at low temperature for UV-curable resin coated fibers. These forces cause fiber microbending for correlation lengths of not more than 1 mm. However, for silicone-nylon coated fibers, axial forces cause fiber buckling for correlation lengths longer than 5 mm. The relationship between the UV-coating structure and loss increase at low temperature is also described.
