Demonstration of spectral slicing WDM system using Light Emitting Diode (LEDs) light source

The study is reported the transmission of a spectral-sliced WDM channel at 1 Gbp/s over LAN with different channel spacing. A sliced channel designed as 1:8 slicing element is integrated, multiplexed, through SMF, and finally demultiplexed into 8 channels namely "spectral slicing" having same spacing bandwidth. The demultiplexer technique is used in WDM and the network applications can apply for Fiber-To-The-Home (FTTH) application. The system performance is characterized according to the Bit-Error-Rate (BER) against the number of bit rates of the system. The significant part of this work is to compare the channel spacing of 0.2-nm, 0.4-nm, and 0.8-nm. Consequently, the study shows that 0.4-nm channel space can transmit signal for LAN access network and the results are significant over 0.8-nm in terms of channel space usages. Therefore, the spectral slicing WDM would be the promising candidate for next generation optical Access Network.
