Title: The Innovations of Daniel Hui Bon Hoa
Introduction
Daniel Hui Bon Hoa is a notable inventor based in Lannion, France. He has made significant contributions to the field of optical fiber technology, holding a total of 3 patents. His work primarily focuses on measuring differential group delay in optical fiber connections, which is crucial for enhancing communication systems.
Latest Patents
One of his latest patents involves a method for measuring differential group delay in an optical fiber connection. This innovative approach allows for the measurement of differential group delay for optical signals undergoing phase modulation, such as BPSK or DPSK. The process utilizes a polarization controller that scans the polarization states of the modulated optical signal. An emulator introduces an additional delay in the modulated optical signal, which is then combined with the non-delayed signal to create a resulting optical signal. The final output is analyzed using a digital oscilloscope or an optical spectrum analyzer to determine the differential group delay.
Another patent focuses on an apparatus designed for measuring the differential group delay in an optical fiber connection. This apparatus includes a generator for producing a binary signal sequence and two polarization controllers that independently scan the polarization states of the incoming and outgoing signals. A differential group delay emulator introduces a variable additional group delay, while an analyzer device detects the equality in the resulting signal sequence.
