Adaptive Bit Error Rate Measurement System

PHYSICAL OPTICS CORPORATION (POC) PROPOSES A NEW BIT ERROR RATE (BER) ADAPTIVE MEASUREMENT SYSTEM (BER AMS) THAT AVOIDS COMMON BER MEASUREMENT ERRORS. THERE ARE CURRENTLY A NUMBER OF BER MEASUREMENT SYSTEMS ON THE MARKET WHICH FOCUS PRIMARILY ON LOW SPEED COMMUNICATIONS, UP TO THE OC-3 STANDARD (155 MHz). UNFORTUNATELY, THESE SYSTEMS ARE NOT ADAPTABLE TO HIGHER SPEED (> 1 HGz) COMMUNICATION SYSTEM, RESULTING IN ERRONEOUS BER MEASUREMENTS FOR HIGHER DATA SPEEDS IN FIBER OPTIC TRANSMISSION LINES OF UP TO TWO ORDERS OF MAGNITUDE. THIS MEANS THAT THE BER MEASUREMENT SYSTEMS CURRENTLY AVAILABLE ON THE MARKET WILL NOT BE ABLE TO MEET THE NEEDS OF HIGH SPEED (> 1 GHz) COMMUNICATIONS SYSTEMS. ESPECIALLY EFFECTED ARE HIGH SPEED FIBER OPTIC DATA COMMUNICATION LINKS WHICH USE DIFFERENT TYPES OF ALPHABET CODES. POC'S ADAPTIVE BER MEASUREMENT SYSTEM PROVIDES A SOLUTION TO THIS PROBLEM. THE BER AMS PROVIDES A MORE RELIABLE DATA COMMINICATION TESTING METHOD WHICH IS ESSENTIAL FOR THE FUTURE DEVELOPMENT OF HIGH-SPEED MILITARY SYSTEMS USING DIFFERENT CODES AND HIGH SPEED COMMUNICATION HIGHWAYS.
