YOEC’s boron-doped stress rod is a kind of preform specially designed and developed for polarization-maintaining fiber. The series of stress rods are prepared by in-tube chemical vapor deposition process, which has the advantages of high boron-doping concentration, good geometric uniformity and large size of stress zone. This series of products are widely used as stress zone materials for stress-applied polarization maintaining fiber and active polarization maintaining fiber.
