Optical Channel Capacity Upgrade Based on Multiwavelength Conversion XGM Using Semiconductor Optical Amplifier for Access Networks

摘要

This paper demonstrates a 10?Gb/s one-to-two-wavelength conversion configuration based on cross-gain modulation for optical access networks using a single TW-SOA. The method is capable of converting a signal data of specific wavelength 1541?nm to certain wavelengths of CW’s laser 1554?nm and 1558?nm with 4?nm spacing. The pump power level was classified due to channel response. A result obtained was the best power level offering wavelength converter between ?6 and 3?dBm. The conversion efficiency achievement provided an acceptable result for probe signals. The findings of Q-factor performance were investigated. The Q values were found to be more than 9 for point to point transmission and 20?km fiber configurations for the original and converted signal. The technique implemented at 20?km and the power of all channels were adequate to provide a splitting ratio of 1/64 for the launched pump power 3?dBm.
