| Summary: | 碩士 === 國防大學中正理工學院 === 應用物理研究所 === 90 === Because of the properties of high speed and capacity, low cost and loss, free from electromagnetic interference, and privacy protected efficiently, fiber optics is becoming a new star in wired communication systems.
Today, as demand for faster data transfer speeds soars, traditional fiber optics systems, which have their own limitations fail to meet the need. The scientists have to seek new technologies for increasing the transmissive ability of fiber optic communication system. There are two key technical developments that are pushing it forward: one is the Impulse Bandwidth and the other is “wavelength division multiplexing”; the latter is the focus of this dissertation.
“Dense wavelength division multiplexing” (DWDM) is a main stream to develop wavelength division multiplexing for the future. It is to narrow down the channel interval (less than 2 nm), so the current fiber optics can transmit wave band in maximum capacity.
The studying methods of this dissertation are to search and collect articles related to DWDM, understand the recent technological developments, discuss and confront the probably problems that DWDM might occur, and then analyze them and compare with every possible solutions in order to catch on the evolution in the future.
