Optical Time Division Multiplexing Technology
Optical time division multiplexing (TDM) technology is a high-speed transmission technology (up to 100Gb / s), it uses very narrow pulses have a greater bandwidth, more efficient use of optical fiber spectrum. TDM will slip stream of light directly into the optical domain multiplexing, resulting in the synthesis of very high bit rate data stream. TDM allows multiple signals simultaneously access to the same fibers, but the realization method of TDM and WDM is entirely different.
TDM can be used to achieve a single light 40Gb / s over rate.
The light source (such as mode-locked laser) produces a series of very narrow optical pulses into N-zero data stream, N a data stream for each channel signal by XGb / s (such as STM-n) respectively, the slip signal modulation, delay one clock cycle, and then by multiplexing the data resulting from the total rate of (N
