This product is a gold-plated fiber optic, with a coating layer made of gold that can withstand high temperatures of 700/650℃ and low temperatures down to -269℃. It is available in single-mode or multimode options, with multimode fiber core diameters of 50/62.5 microns, in step-index or graded-index configurations. The fiber core is made of silica. Gold-plated fiber optics (optical fiber) are suitable for use in various high and low temperature resistant fiber optic jumpers, optical fiber pigtails, fiber optic grating sensors, distributed optical fiber sensors, and sensing cables produced by Beijing Dacheng Yongsheng Technology Co., Ltd. (short for DCYS), which utilize a stainless seamless steel pipe structure.
Product brand is OFSCN®.
