Description
Tunable FBG is a good solution for many applications including where corrected central Bragg wavelength is necessary. Central wavelength of FBG strongly depends on applied stresses. The mechanics induced strain to the FBG shifting linearly its central wavelength. Relative strain sensitivity of FBGs wavelength is 0.78 10-6 µstrain-1. The tunable FBGs are boxed and operated manually. Athermal performance with adjustment range of 3 nm is also possible. Optical connectors or bare fiber are a possible bundled of equipment.
