本論文旨在測試雙向和三向光纖傳輸系統的穩定度分析，依不同光源將架構設計為單波長、分波多工和不同波長的傳輸模式，且以不同波長的模式結合10 Gbit/s和2.5 Gbit/s電訊號傳輸，主要測試波長訊號的同頻和臨頻干擾的影響，本實驗設計的架構幾乎為對稱的形式，在功率量測和光頻譜分析儀的測試下得到差不多的功率與頻譜結果，因此接收端訊號僅選定以1552.5 nm為主要訊號的檢視波長，以維持測試儀器在一樣的條件下來比較，且以0公里、25公里和50公里單模光纖測試，得到使用帶通濾波器而未接有色散補償可提升2-3 dB的功率償付。以雙向傳輸來切入主題，各波長的通道間距為0.8 nm作為實驗的標準，在實驗得到僅有1.5 dB的損耗，而頻帶內的串擾約在-37 dB左右，在單波長傳輸模式不同距離下的功率償付為0.482 dB、0.887 dB和1.592 dB；分波多工傳輸模式不同距離下功率償付分別為0.631 dB、1.002 dB和1.773 dB；不同波長傳輸模式不同距離的功率償付為0.214 dB、0.392 dB和0.926 dB；最後在不同速度混成且不同距離下功率償付為0.114 dB、0.368 dB和0.514 dB。而在三向傳輸可分為有無光開關連接，光開關的切換又分為交叉和平行切換方式，而實驗的損耗在2-4 dB間，有接光開關功率償付有微幅上升0.1-0.2 dB，以最差的情形比較，其2×2光開關交叉且未接光纖的四種架構功率償付依序為0.621 dB、0.756 dB、0.317 dB和0.329 dB。最後以布拉格光纖光柵式光交叉鏈路2×2和3×3同波長和分波多工測試；其路徑2×2 OXC最大損耗為2.5 dB；3×3 OXC最大損耗為7.5 dB，2×2 OXC光柵反射未接光纖時，同波長和分波多工功率償付分別為0.709 dB和0.855 dB，而3×3 OXC功率償付則為0.658 dB和1.009 dB，其得知在帶內串擾為-10 dB時會造成功率償付為0.832 dB。

The subject of the thesis is mainly to test the stability of bi-directional and tri-directional fiber transmission system, design the transmission methods, which are single wavelength, wavelength division multiplexing (WDM), different wavelengths, and the integration of electrical signal 10 Gbit/s and 2.5 Gbit/s based on the transmission method in different wavelengths according to the change of light sources, and change the corresponding architectures. The goals are to test the influence of the signal with the same and adjacent channel interference. The architecture design in the experiment is almost in the paralleled type, with the power measurement and Optical Spectrum Analyzer (OSA) getting the similar power and the spectrum, respectively. So, we select 1552.5 nm as the wavelength of the signal in the receiver to keep the instruments working under the same condition to make a comparison. In addition, we test it with the increment of additional 25 km and 50 km single-mode fiber (SMF) and get the result that using band-pass filter (BPF) without dispersion compensation could enhance 2-3 dB power penalty. From bi-directional transmission to cut to the point, the standard in the experiment requires the gap between each channel with 0.8 nm. The result shows that the loss is only 1.5 dB and the intra-channel’s crosstalk is about -37 dB. In single wavelength transmission methods with different distances, the power penalties are 0.482 dB, 0.887 dB, 1.592 dB, respectively. In WDM transmission methods with different distances, the power penalties are 0.631 dB, 1.002 dB, 1.773 dB, respectively. As for the transmission methods with different distances, the power penalties are 0.214 dB, 0.392 dB, 0.926 dB, respectively; With the hybrid speed under different distances, the power penalties are 0.114 dB, 0.368 dB, 0.514 dB. In tri-directional transmission, there are with/without optical switches, which could be separated into bar switch and cross switch. The experiment result shows that the loss is around 2-4 dB and the power penalty slightly increases 0.1-0.2 dB with optical switch. To use the worst condition to make a comparison, the power penalties of the cross switch without fiber in different architectures are 0.621 dB, 0.756 dB, 0.317 dB, 0.329 dB. Finally, we use 2x2 and 3x3 optical cross connect (OXC) based on FBG with the same wavelength and WDM to test. The maximum loss for 2x2 OXC is 2.5 dB and 7.5 dB for 3x3 OXC. When 2x2 OXC is without the fiber, the power penalties for the same wavelength and WDM are 0.709 dB and 0.855 dB, and 0.658 dB and 1.009 dB for 3x3 OXC and we could realize that it will lead to power penalty with 0.832 dB when intra-band crosstalk is -10 dB.
