碩士 === 明志科技大學 === 電機工程系碩士班 === 102 === Advancement of technology, published in recent years, many new technologies and techniques, such as cloud technology, smart appliances, etc. These techniques are often accompanied by high-bandwidth, high -capacity, fiber-optic communication transmission systems can achieve this goal. In order to meet human needs for bandwidth and mobility, an integrated radio over fiber (ROF) and passive optical network (PON) for hybrid fiber optical network (ROF-PON) architecture is increasing attention. This paper presents three kinds of structure, structure (I) mainly using intensity modulator is loaded local oscillator of 15GHz to generate optical double sideband, and then separation of the central carrier and subcarrier is used fiber Bragg grating, transmission to the client through different paths do signal quality testing. Structure (II) and structure (III) are a combination of structure (I) in a downlink transmission scheme, the Detection of downlink and remodulation in uplink transmitted are from the central carrier. In the structure (II) and (III), the uplink is using intensity modulated manner and phase modulation manner, respectively. In this paper will explore the uplink modulation is using different modulation schemes for the quality of the transmission systems in the structure (II) and (III).
