HIGHLY PARALLEL REAL-TIME FIBER OPTICAL MULTI-WAVELENGTH NETWORK FOR LONGER DISTANCE PERSONAL MULTI-MEDIA CONFERENCING

FOR IMPLEMENTING MULTI-MEDIA CONFERENING AND COLLABORATION SERVICES BETWEEN WORKSTATIONS, PHYSICAL OPTICS CORPORATION (POC) PROPOSES A HIGHLY PARALLEL REAL-TIME FIBER OPTICAL MUTLI-WAVELENGTH NETWORK BASED ON MULTI-MODE (62.5/125) FIBER OPTICS, MUTLI-LONGITUDINAL MODE (MLM) LDS, AVALANCHE PHOTODIODE (APD) RECEIVERS, AND POC'S COMMERCIALLY AVAILABLE WAVELENGTH DIVISION MULTIPLEXERS (WDMS). IN ADDITION TO PROVIDING THE STANDARD FEATURES ASSOCIATED WITH FIBER OPTIC LINKS (HIGH BANDWIDTH, LOWER WEIGHT, IMMUNITY FROM EMI AND EMP INTERFERENCE), POC'S MULTI-WAVELENGTH NETWORKS HAVE IMPORTANT ADVANTAGES OVER OTHER CURRENT STATE-OF-THE-ART NETWORKS: AN EXCELLENT POWER BUDGET MARGIN ALLOWS FOR THE USE OF A SIZABLE VARIETY OF PASSIVE COMPONENTS SUCH AS WDMS, STAR COUPLERS, EO SWITCHES AND MODULATORS, AND NARROW-BAND SPECTRAL FILTERS. THE SYSTEM POSSESSES HIGH TRANSPARENCY (AT LEAST -25 DB OPTICAL CROSSTALK OR -50 DB ELECTRIC CROSSTALK). IT IS POSSIBLE TO PROVIDE MULTI-MEDIA (VIDEO, VOICE, COMPUTER DATA, SENSOR DATA) HIGH SPEED (100 MHZ/S OR 100 MB/S) TRANSMISSION WITHIN A SINGLE FIBER. THIS CAN EITHER GREATLY REDUCE THE REQUIRED NUMBER OF CABLES OR SIGNIFICANTLY INCREASE SYSTEM REDUNDANCY AND CAPACITY. ANTICIPATED BENEFITS/POTENTIAL COMMERICAL APPLICATIONS - POC'S FIBER OPTIC NETWORK SYSTEM IS REAL-TIME, WIDE BANDWIDTH, HIGHLY PARALLEL, MULTI-CHANNEL, LOWER COST, IMMUNE TO EMI AND EMP, PROVIDES MORE REDUNDANT CHANNELS FOR EXTENDING COMMUNICATION CAPABILITIES, AND CAN BE READILY COMBINED WITH OTHER KINDS OF NETWORKS FOR COMMERCIAL APPLICATIONS.
