Bidirectional coupler for communication over a single fiber

WebA wide variety of couplers is available, from single-power monitors with a low coupling ratio, to dichroic couplers which feed in pump power to a signal-carrying fiber at one wavelength without causing any loss of power at the signal wavelength. The most important element is the fiber grating which has had an impact comparable to that of the EDFA. WebLensed dichroic couplers would provide the wavelength selectivity. Air Force system II, an eight-wavelength, codirectional, 300-Mb/s, point-to-point system, was designed using laser diode sources with channel wavelengths from 760 nm to 847.5 nm. Silicon pin detectors were used and dif-fraction grating mulitplex/demultiplex couplers were selected.
