Features:

Designed to provide high level of cladding mode suppression
High level photosensitivity reduces time needed to write gratings
Acrylate coating strips easily to simplify FBG processing
Mode-field compatible with standard SMF to decrease splice loss
Excellent for high-quality Fiber Bragg Gratings (FBGs)

Applications:

Fiber Bragg Gratings (FBGs)
Telecommunication networks
Quasi-distributed sensing
Optical add/drop filters
Pigtails in telecom devices
Gain-flattening filters (GFF) for EDFAs

VSS200 Photosensitive Fiber is a single-mode fiber with modified glass chemistry designed to enhance the sensitivity of the glass core to UV light, which allows for high efficiency, high quality Fiber Bragg Grating (FBG) writing with extremely short UV exposure. The high glass sensitivity of this fiber allows for FBG writing 5 times faster than with standard single-mode fibers, which significantly increases productivity in mass production of FBGs. This fiber is also suitable for FBG arrays used in quasi-distributed sensing applications.
