Sensor technologies are undergoing revolutionary advances. Increases in spatial, spectral, and temporal resolution, and in breadth of spectral coverage, render feasible sensors that function with unpr...
Bandwidth Measurement of Multimode Fibers through System Level Bit Error Rate Testing
Bandwidth Measurement Multimode Fibers Bit Error Rate Testing
2015/5/18
A new bandwidth measurement method for multimode fibers is developed through measuring bit error rate and power penalty associated with the testing system. Experimental calibration procedure and actua...
Time-Resolved Error Vector Magnitude for Transmitter Mask Testing in Coherent Optical Transmission Systems
Time-Resolved Optical Transmission Systems Mask Testing
2015/5/15
We propose a novel transition-sensitive measurement approach for coherent optical systems. The time-resolved error vector magnitude (EVM), combined with mask testing, is a powerful tool for pass/fail ...

Smart structures that emulate human muscles and skin and nondestructive testing of bridges and airline cargo will be among advances presented at an international conference in San Diego, California, n...
A new optical fiber line testing function for service construction work that checks for optical filters below an optical splitter in a PON
Fiber measurements Fiber Bragg gratings
2015/6/5
We propose a new function for construction-work undertaken to install optical cables for services in PONs. We demonstrated to determine whether an optical fiber is “live” or “unused”in branched fiber-...
