Instantaneous Monitoring of the Quality of Signal of Optical Links
Summary
Ohio State researchers have developed a novel method of signal quality monitoring that can reliably assess the quality of a digital signal in as little as 100 picoseconds, thousands of times faster than traditional bit-error rate (BER) or eye diagram testing. The technique compares bit shapes in an all-optical system to detect the combined effects of attenuation, dispersion, noise, and timing jitter. The hardware is simple, compact, and far less expensive than traditional QoS systems. This system allows users of optical links to quickly and accurately assess their data quality. Using this information, more intelligent networks can be designed and implemented.
Main Advantages of Technical Approach
- Compact, simple, inexpensive hardware
- Orders of magnitude faster than traditional electronic bit error rate measurement
- Instantaneous monitoring of optical link quality
Market Potential
- Optical performance monitoring
- Optical routing and switching
- Digital communication systems (electronic or optical)
