Abstract
A method of receiving wavelength multiplex signals is designed to receive together, at an end of an optical fiber transmission path, optical information signals transmitted in multiple wavelengths, which correspond to multiple kinds of information, from a plurality of information sources distributed at a virtually constant interval along the transmission path in response to an optical trigger signal. Each of the optical information signals is sampled at a time interval that is in inverse proportion to the light velocity which depends on the wavelength of the signal, so that the content, kind and source of information are identified at the signal reception.
Claims8
A method of receiving wavelength multiplexed optical signals at the end of an optical fiber transmission path, wherein said multiplexed signals are transmitted in response to an optical trigger signal and represent multiple kinds of information respectively from a plurality of information sources distributed along said transmission path at essentially constant intervals, comprising the step of:
- sampling said wavelength multiplexed optical signals respectively at time intervals inversely proportional to the light propagation velocities of said multiplexed signals, whereby the content, kind and source of information of each of said multiplexed signals may be identified at the end of said transmission path.
