What the paper is about?
The research paper does two things. First of all, the research proposes a realistic design of a WDM-PON based on a silica microresonator. Optical frequency comb (OFC) is generated in the dissipative Kerr soliton (DKS) regime. Additionally, we show that microresonator-based OFCs with a linewidth of up to 100 MHz can be used for non-return-to-zero on-off keying (NRZ-OOK) modulated data transmission system and give an acceptable bit error rate (BER). Basically, we investigate data transmission performance in 8-channel 100 GHz spaced WDM-PON for OFC carrier linewidths of 100 kHz, 1 MHz, 10 MHz, and 100 MHz using intensive numerical simulation.
Obtained results
The data transmission results show that error-free data transmission is possible with a BER of 4.4×10-12 for 100 kHz OFC carrier linewidth, providing 80 Gbps of total data rate on eight OFC-generated carriers. The linewidth of 100 kHz provides the best system performance based on transmission distance, received optical power, tone-to-noise ratio (TNR), and bit error rate (BER) values.
Data transmission over 50 km of SMF fiber distance, corresponding to the evolving Super-PON standard, verifies the feasibility of the investigated system also for 1 MHz, 10 MHz, and 100 MHz OFC carriers, providing BER values below the forward error correction (FEC) threshold of 1×10-3
