Analysis with gain and power for better coverage of FTTH network using WDM-PON architecture

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