This product is a multimode polyimide fiber optic (optcial fiber) that can withstand both high and low temperatures. The coating material is polyimide, with options for 50/62.5 diameter, step-index/gradient-index, non-carbon coated/carbon coated, doped/pure silicon core. It is suitable for various high and low temperature-resistant fiber optic jumpers, fiber optic pigtails, fiber optic grating sensors, distributed fiber optic sensors, and sensing cables produced by Beijing Dacheng Yongsheng Technology Co., Ltd. (short for DCYS), which use a stainless seamless steel tube structure. Product brand is OFSCN®.
