FIELD: fiber-optic engineering. ^ SUBSTANCE: fiber-optic splitter has X-splitters connected together. Input terminals of X-splitters, which are free of connection, have to be n input terminals of star-type splitter. Output terminals of X-splitters being free of connection have to be its output ports of star-type splitter. Couplings between X-splitters are made to form (n-1) circuits, connected in series by first output and input terminals of X-splitters. First circuits have (n-1) splitters. X-splitter, being the first in circuit, has both input terminals free; subsequent X-splitters in circuit have second input terminals being free. Any subsequent circuit has one X-splitter less than previous circuit. ^ EFFECT: elimination of initial losses of star-type splitter at any number of input/output terminals. ^ 2 cl, 2 dwg |
