20 Gbps Bidirectional Transmission via Four Channels over Long-haul SMF in a WDM-PON Architecture using External Modulation Scheme

In this work, we propose a sixteen channel wavelength division multiplexed passive optical network (WDM-PON) architecture which provides seamless connectivity between mobile switching center (MSC) and base transceiver stations (BTS) and also serves the fiber to the home (FTTH) users. WDM-PON based mobile backhaul network is considered to be a prime solution due to its quick deployment and reduced cost. Due to growing demand for connectivity and data transmission, the number of wavelengths are increasing day by day. The bit error rate (BER) performance is analyzed for the discrete data rates per wavelength (viz. 2.5 Gbps, 5 Gbps, 10 Gbps, 20 Gbps, and 40 Gbps) at discrete reach for 16 channel WDM-PON. The optical spectrum of sixteen channel WDM-PON is observed for different data rates at multiplexer output and the same is analyzed after fiber distance of 20 km. The fiber reach of the WDM-PON is varied, and its effect on the performance parameter like bit error rate (BER) and Quality Factor (Q-Factor) is observed on BER analyzer for the discrete data rates per wavelength. It is found that as data rate per wavelength increases, the error-free reach of the WDM-PON system decreases. Proposed WDM-PON architecture performs superior to the compared work under similar initial conditions.

Here, we have simulated different unidirectional passive optical networks (PONs) technologies such as wavelength division multiplexing (WDM), time-division multiplexing (TDM) and hybridPONs with different users for varying fiber length, data rate, continuous wave laser power and number of users. Their performances based on the quality-factor (Q-factor) and bit error rate (BER) using OptiSystem software 7.0 with using an Erbium doped-fiber amplifier (EDFA) were compared. Our model used 16 and 128 users, where the performance of the unidirectional Hybrid WDM/TDM PONs with 4 wavelengths and 128 user systems have better high Q-factor and lower BER, compared to that of 128 user WDM PON and 128 user TDM PON systems.
