Increasing Residential Capacity in Gigabit-capable Passive Optical Network using High Splitting Ratio

Abstract

Nowadays, multimedia technology has led to broadband services such as the delivery of data, voice, and video or multiple-play services. PONs (Passive Optical Networks) gives these services worthwhile. Fiber to The Home (FTTH) with Gigabit-capable PON, is generally based on tree network topologies that use passive optical splitters. Splitting level for passive optical splitter can be employed in one or two levels in Optical Distribution Networks (ODNs) with the configuration of passive splitter 1:2, 1:4, 1:8, 1:16, 1:32, and 1:64. This paper discusses FTTH deployment using a high splitting ratio method by utilizing 1:8 passive splitters in each of the two levels in ODNs for residential areas. This high splitting ratio can increase the user capacity for the time ahead of user scaling. The proposed method is simulated by employing Optisystem software. The power link budget and bit error rate (BER) are considered as the G-PON eligibility standards in this paper. The received power and BER meet the eligibility standard set by ITU-T G.984.2, which is greater than −28 dBm, and not worse than 10-12 for broadband services, respectively. This method illustrates that the proposed configuration can be implemented in a rapid residential because every G-PON port can serve 64 users. It escalates 2560 users for every G-PON network, which is double the number of increasing users than the usual splitting method of 1: 4 and 1: 8.
