RF/PON based Gigabit Transmission System for Ultra-Broadband Cable Network

Abstract

To keep up with increasing bandwidth demands, cable network operators are migrating to fiber networks, which promise to deliver Gigabit speeds. However, migration to an all-fiber network infrastructure requires major investment and takes considerable time to complete. New network technologies and the demand to improve the quality of experience (QoE) are driving network operators towards the Ultra-Broadband era. The Ultra-Broadband Cable Network can be implemented in two ways: a coaxial-based access technology and a fiber-based access technology. However, those existing technologies have problems such as problems at extension of up/down stream frequency, cost of upgrading the network. This paper proposes the RF/PON based gigabit Transmission system in order to provide the 1Gbps internet and the N-Screen to IP devices.
