| Summary: | 博士 === 國立臺北科技大學 === 光電工程系研究所 === 100 === Optical fiber with characteristics like low attenuation, high bandwidth, high speed, and electromagnetic noise interference (EMI) free is widely used in constructing communication transport systems. As a communication medium, glass single-mode fiber (SMF) offers much better performances than plastic optical fiber (POF). Also, glass single-mode fiber (SMF) can apply in backbone and access network. Nevertheless, fiber optical communication systems for last mile end user applications have not yet addressed. Building a feasible and an economical technique structure to fit in with last mile end user applications is a big challenge.
In recent years, some new POFs, such as perfluorinated graded-index plastic optical fiber (PF GI-POF), have been developed with better performance and low cost. In this dissertation, we present several ways to verify optical transport systems access network with build-in PF GI-POF. PF GI-POF access network can be a candidate for last mile end user applications.
Furthermore, we proposed two light sources and demonstrated that they can conform to application of fiber-to-the-X (FTTX) and radio over fiber (ROF) transport system, respectively. One light source based on a broadband amplified spontaneous emission (ASE) is for FTTX/ROF transport system; the other light source combined an economical multi-band optical carrier generator with a novel optical signal to noise ratio (OSNR) enhancement circuit is for radio over fiber transport systems.
