Clock Distribution Using Optical Wavelength Division Multiplexing Techniques

The use of optical wavelength division multiplexing (WDM) for the simultaneous transmission of clock and data signals has possible application in the interconnection of communications equipment. This paper presents experimental results from transmitting clock and data signals through a single-mode optical fibre using WDM and highlights a technique to overcome phase mis-alignment between the clock and data signals at the point of retiming.
