Investigation of Performance Affecting Parameters on Hybrid Passive Optical Networks

Abstract

AbstractIn the evolvement of current passive optical networks (PONs), there is ever increasing bandwidth demand due to dynamic service requirements. This introduces challenge for the choice of multiplexing technique and physical layer bounds like fiber length, data rate, and number of users are critical over a suitable architecture. In this article, hybrid wave division multiplexing-time division multiplexing PON is analyzed using variable length of fiber with data rates up to 40 Gbps over a maximum of 128 end users. Comparative study using different frequency spacing’s has shown that it has negligible effect on the Q-factor performance parameter. Further in the work, variable data rates required for different services is successfully transmitted up to 30 km to 128 number of users for an acceptable level of bit error rate.
