David W Stowe, Paul W Fitzgerald, Frederick J Gillham: Miniature fiberoptic bend device and method. Aster Corporation, Fish & Richardson, August 11, 1992: US05138676 (69 worldwide citation)

Bends in optical fibers can be miniaturized by reducing the diameter of a section of the fiber in the region where bending is desired to a condition in which the optical properties of the fiber have reduced bend-loss sensitivity. In one aspect of the invention, radii of curvature less than 100 micro ...

For communicating over optical routes, route monitoring and protection are provided. In routes carrying signals on each of a number of wave lengths a tapped fraction of the signal is demultiplexed and an individual wave length is detected for determining performance and for triggering switching to a ...

Jisen Xu: Fiber optic coupler. Aster Corporation, Fish & Richardson, May 8, 1990: US04923268 (31 worldwide citation)

A fiber optic coupler and method for forming such coupler is shown in which the substance of the fibers is preselected to have a heat fusing temperature in a range achievable by exterior heating of a shrink sleeve, and the fibers are heat fused together along a limited length region within the shrun ...
