Abstract
A splice loss tester for optical fiber splices has two light launch stations and a detection station. The light launch stations each have an optical coupling block formed of acrylic or other transparent material, with a concave surface on which an arcuate segment of the fiber is lightly biased by a cylindrical anvil. A photoemitter in optical contact with the coupling block generates light at a suitable wavelength (e.g. 1550 nm). A clear silicon gel layer on the block concave surface can hasten fiber stabilization. The detection station has a similar coupling block and anvil, and a pair of photodetectors to detect light leakage in each of two directions. The light is launched or detected over a substantial arc of the fiber, i.e., about ninety degrees, and the launch and detection units are useful over a wide range of wavelengths.
