G02B6/2843 - CPC Classification

Classification description:

Light guides; Coupling light guides; Optical coupling means having data bus means, i.e. plural waveguides interconnected and providing an inherently bidirectional system by mixing and splitting signals forming multipart couplers without wavelength selective elements, e.g. "T" couplers, star couplers using lateral coupling between contiguous fibres to split or combine optical signals the couplers having polarisation maintaining or holding properties
