The patented Litton FORJ consists of adjacent optical waveguides, each of a "U" channel cross section, that accept an incoming optical beam and "form" it into a circular pattern around the circumference of the waveguide.
The FORJ became the bridge that led the company into the broad range of optical and electro-optical products, including couplers, wave division multiplexers, sensors and hybridized analog and digital transceivers.
Available variations of Stratos FORJs include units for submersion in water, for high pressure, for miniature systems, for high RPM, for multi-fiber cables, and for broad spectral range use.
