Optical Time Division System to Replace Standard Matrix Switching

THIS PROPOSAL ENCOMPASSES A NEW TECHNOLOGICAL IDEA. THIS IDEA IS BASED ON A PATENTED WORKING OPTICAL BACKPLANE TECHNOLOGY WITHOUT FIBEROPTICS. PROJECT ENGINEERS THROUGHOUT THE U.S. HAVE LONG SOUGHT AFTER A REPLACEMENT FOR COMPLEX, UNRELIABLE MATRIX SWITCHING. THIS TECHNOLOGY ELIMINATES ALL RELAY MATRICES AND CMOS INTEGRATED CIRCUITS. THESE DEVICES ARE CURRENTLY USED FOR BOTH SWITCHING ANALOG SIGNALS AND DATA. IT INCREASES RELIABILITY BY ELIMINATING MOVING CONTACTS. THE DIGITAL OPTICAL TECHNIQUE EMPLOYED PROVIDES INFINITE SIGNAL ISOLATION AND ZERO CROSSTALK. BBT TECH'S SYSTEM EMPLOYS ULTRA-HIGH-SPEED TIME DIVISION MULTIPLEXING. THE IDEA IS SIMILAR TO THAT USED IN TELEPHONY. HOWEVER, THIS SYSTEM OPERATES AT SUSTAINED DATA RATES OF SEVERAL HUNDRED MEGABYTES TO ONE GIGABYTE PER SECOND OR FASTER. THE OPTICAL BACKPLANE IS CONSTRUCTED FROM SIMPLE PLASTIC MATERIALS, AND INJECTION MOLDED FOR ONLY A FEW DOLLARS PER SYSTEM. MATRIX SWITCHING TECHNOLOGY HAS NOT CHANGED SINCE 1970 WHEN REED RELAYS REPLACED THE POPULAR CROSSBAR SWITCH. MULTI-STAGE SWITCHES PROVIDE PATH REDUNDANCY. TROUBLESHOOTING PROBLEMS FOR THESE SYSTEMS ARE BOTH DIFFICULT AND TIME CONSUMING. MULTI-STAGE SWITCHING BECAME POPULAR BECAUSE OF UNRELIABLE NATURE OF RELAY CONTACTS. THE TECHNOLOGY IN THIS PROPOSAL IS BASED ON SOUND PRINCIPLES. IT ELIMINATES RELIABILITY PROBLEMS. THE BENEFITS ARE REAL AND CAN BE PROVED.
