Nanjing Wasin Fujikura high temperature resistant optical fibers have good optical properties, excellent dynamic fatigue properties and high tensile strength under high temperature conditions.Wasin Fujikura has two series of high temperature resistant fibers, at 200 degrees and 350 degrees
Feature
► Good high temperature performance
► Stability performance under Continuous cycle of intense low-temperature and high temperature (down to -55 ° C up to 300 ° C)
► Low loss, wide band (from near ultraviolet to near infrared band, 400nm to 1600nm)
► Good resistance to optical damage ability
► 100KPSI strength level
► Process is flexible and can be customized to realize different geometry, fiber profile structure, NA, and so on.
