中文摘要 | 由於光纖傳輸線路架設環境不同,周遭溫度變化所造成折射率值的改變會使零色散波長發生偏移。本文分析溫度變化對單模態光纖零色散波長偏移之影響,結果顯示傳統單模態光纖在λ0=1.3μm的偏移率為0.022nm/℃,而在λ0=1.55μm附近之色散偏移光纖,偏移率為-0.051nm/℃,方向與λ0=1.3μm單模態光纖相反,因此在高頻寬的通信系統,λ0=1.55μm比λ0=1.3μm的單模態光纖通信系統較須考慮溫度的影響因素。 |
英文摘要 | Since the difference of the fiber transmission environment, the index difference caused by the conversion of temperature will shift the zero dispersion wavelength. In this study, the attention is concentrated in the effects of zero dispersion wavelength shift of single-mode fibers. The result shows the variation rate is 0.22nm/℃ while the traditional single mode fiber is at λ0=1.3μm. However, the variation rate is -0.051nm/℃ while the fiber is at λ0=1.55μm. At the same time, the direction of the dispersion is inverted. Hence, in the wide band communication system, the temperature is an important factor needed to be consider when the single-mode fiber of λ0=1.55μm is used instead of the one ofλ0=1.3μm.. |
