Photosensitive Preforms

They can be used to reflect, filter or disperse light within an optical fiber. FBGs can be used in the fabrication of optical strain and temperature sensors, with quasi-distributed measurements possible using gratings written sequentially into a continuous length of fiber.

InfoGlas® PSP series - the industries only preform product that allows FBG imprinting during fiber drawing processes.

The PSP series of preforms was designed for a wide range of applications. Their ease of fabrication and use combined with their unique properties and great advantages make them ideal for a great number of applications in telecommunication, fiber sensors and lasers. It is a good choice for Type I gratings, due to its high germania content; the high NA reduces loss under tight bends; the PSP allows for low splice loss to other fiber with high NA, such as Raman amplifyer fiber.
