Abstract
To fulfill the future demand for high data rate, novel research has been carried out which provides high-performance and secured communication from the optical line terminal (OLT) to the optical network unit (ONU). Results have been incorporated with simulations in optical simulation software called Opti-system. Gain and power estimation has been considered for long reach using wavelength division multiplexing passive optical network (WDM-PON). This method evolves with time and extends to mobile, local area, and metro area access networks. Finally, it has been predicted that the system data rate can reach (2.5 × 8) 20 gigabits per second (Gbps) up to a maximum of 80 km (km). The distance limit for larger data speeds (i.e., 5Gbps or 10 Gbps) was 80 km with a power of 30 dBm. A higher data rate of 40 Gbps per channel was achieved successfully at 30 km, i.e., a maximum data rate from 80 Gbps (10 × 8) to 320 Gbps (40 × 8) can be achieved with novel optimized WDM-PON architecture. Bit error rate (BER), quality (Q) factor, and eye height have limited within the acceptable range as per international telecommunication union (ITU) standards to achieve and fulfill the future demand of 5G (generation) or 6G-based applications at the last mile.
