200℃ Polyimide Optical Fiber - SM/MM High Temperature Optical Fiber - PI Optical Fiber - Doped/Pure Silica Core Fiber Optic - Sensing Communication Optical Fiber

This product is a polyimide optical fiber with a medium-temperature polyimide coating. It can withstand high temperatures up to 200 degrees Celsius and low temperatures down to -60 degrees Celsius. It is available in single-mode or multi-mode configurations. For multi-mode fibers, the core diameter can be selected as 50/62.5 microns. The optical fiber core is either doped or pure silica.

Compared to high-temperature polyimide optical fibers, the 200°C polyimide optical fiber further refines the fiber's adaptable temperature range and reduces the cost of use. This 200°C polyimide optical fiber is suitable for various high and low-temperature resistant fiber patch cords, pigtails, fiber grating sensors, distributed fiber optic sensors, and sensing cables produced by Beijing Dacheng Yongsheng Technology Co., Ltd.

Product brand is OFSCN®.
