FBG Array
Description
FBG Array is a
series of Bragg grating written on a single optical fiber. It can meet the
requirements for long monitoring and multi-points monitoring. It can improve
the stability and reliability, as well as simplify the system. AtGrating can
customize the FBG array for different customers.
