Abstract
The specification describes an optical fiber grating package with means for controllably adjusting the strain in the optical fiber grating count. The package is provided with two threaded members with different thread counts so that when both members are simultaneously turned axial displacement results, and the magnitude of the displacement is determined by the difference between the axial displacement of the two threads.
