Durable fibers having a thin Ti-doped silica surface layer were fabricated by using the refined fabrication process of compressive cladding. High surface-compressive stresses up to 0.69 GPa (100 kpsi) resulted in significant improvement in fatigue resistance of optical-fiber waveguides.

Effort involves investigations of fiber, cabling, and connector development on an individual as well as combined basis for meeting requirements of tactical TDM communication systems. During this reporting period, extensive testing and evaluation of three six-.. fiber cables was performed in accordance with technical guidelines.
