Product Description: 
 FiberLogix pure silica fiber than ordinary fiber has better high-temperature high-pressure characteristics of the hydrogen loss is very small. Practice has proved that the fiber service life compared to pure silica fiber in the wells under the conditions of ordinary resistance to high temperature is greatly increased. 

 Important features: 
 Operating temperature -50 ~ +350 C 
 Can add a carbon seal coating 
 Singlemode and multimode products 
 Can provide a variety of wavelengths and optical fiber 
 Pure silica (quartz) core diameter to reduce the hydrogen loss
