    摘要: 電子資訊的傳遞，在網路普及應用的今天，扮演著重要的角色，加上雲端架構與技術日漸普遍與成熟，未來在資訊傳遞上的重要性與安全性，更是考驗著各種架構的發展或電子交易應用的成功與否的關鍵因素。
    本論文針對光纖傳輸所產生洩漏（leaking signal）及衰減的特行進行研究。訊號的傳遞可分為電子訊號與光訊號，以電子訊號傳輸而言，電波在導線中傳遞，所產生的洩漏或是使用搭接的方式，讓有心人士有機會進行訊號竊取；以光訊號傳輸來說，光訊號透過光纖傳送，沒有電波洩漏的疑慮，安全性雖高，但接續、接頭或是彎曲半徑過大所造成的衰減損失（loss），亦可能造成訊號被竊取的因子。
    光纖傳輸系統架構及應用越來越普及，依重也越來越高，當大家在討論傳輸內容安全性的同時，對於傳遞中訊號的安全性，也應該被重視，再嚴謹的加密演算法，一旦訊號被竊取，破解加密取得正確的內容，也僅是時間上的問題；本研究提出光訊號在傳輸過程中，相關的模擬實驗，來顯示光訊號被竊取的可能性。

    Today, electronic transmission of information play an important role in the network of universal application with the cloud framework and technology become more commonplace and mature. Information transmission and security is more important in the future, it's to test the various schema developments or a key factor in the success of electronic trading applications.
    In this thesis, Leaking Signal Optical Fiber Transmission and attenuation produced by the special line of research. Signal transmission can be divided into electronic signals and optical signals. Electronic signal transmission is concerned wave flow through the wire, this way disclosure or use of lap; let people who are interested have the opportunity to signal theft. As far as optical signal transmission, optical signals through optical fiber transmission, no wave leakage concerns and security was high but continued, joints or attenuation losses caused by the bending radius is too large, may also be caused by factors of signal theft.
    Structure and application of optical fiber transmission system is becoming increasingly popular, according to weight are also increasing, when everyone in the discussion of security while delivering content. For the safety of the transmission of signals, it should be taken seriously, re strict encryption algorithm, once the signal is stolen, crack the encryption to get the right content, it is only a matter of time. In the course of this study optical signal transmission, related simulation experiment to show the possibilities of optical signal theft.
