High temperature resistant acrylate fiber

Fujikura's single-mode and multi mode optical fibers with high temperature resistant acrylate coating protect the optical fibers up to 200°C. The fibers are applied to harsh environments like Oil & Gas industry. Figure1 shows the results of attenuation variation in 200°C. We obtained not more than 0.01 dB/km variations at both 1310 nm and 1550 nm. Table1 and 2 show the specification of the fibers.
