 ACOUSTO -OPTIC SWITCHING MODULES WITH FIBER-OPTIC ARRAY
Russian Technological Association™ presents a range of all-optical switching modules allow optically connect the single input fiber with any of (2 - 1024) output fibers assembled in the Fiber-Optic Array* (FOA). RTA developed especially technologies** allow to assemble required numbers of single mode fibers as well as multimode fibers in an Fiber-Optic Array with specified parameters compatible with input-output optics of concrete module. The needed address (X-Y coordinates) of required fiber from FOA is specified and depended of RF signal on Two Dimensional Acousto-Optic Deflector (2-D AOD) that is a core element of all developed modules.
FEATURES  All optical unit (no mechanical parts);
Large number of switching channels;
Low switching (reconfiguration) time;
Small size.
