Info about Optical Time Division Multiplexing
Optical time division multiplexing (OTDM) is a powerful and scalable technique to investigate high-speed data transmission systems, related signal processing and monitoring technologies at serial data rates beyond the bandwidth limitation of (opto) electronics. The OTDM technique is fundamentally compatible with modern multi-level quadrature-amplitude modulation formats and digital coherent detection.
In contrast to wavelength division multiplexing (WDM), only one wavelength ("color") of light is used.

The operation principle of OTDM is as follows: Different optical pulse streams, called tributaries, originating from the same laser (same central wavelength), are separately encoded by electrically generated data signals. Due to the low duty cycle of their pulses (1.5 ps at 10 GHz) the tributaries are serially bit interleaved in order to form the high speed serial OTDM data signal. At the receiver end, an ultra-fast optical clock and data recovery extracts the individual time-domain tributaries, which are subsequently processed by conventional (opto)electronics.
