This thesis focuses on the design and fabrication of the optical link module of NTU-Array. NTU-Array is a microwave interferometer which is made for probing the high red-shift objects by measuring the SZ effect. In Chapter 1, we introduce the scientific goals and a framework of NTU-Array. Chapter 2 and Chapter 3 describe the design and fabrication of optical link module. The benefit of transferring signals by the optical fiber is that the attenuation will not increase dramatically with distance. In Chapter4, we describe the measurement results of the gain equalizer and the optical link module. In Chapter 5, we summarize our work and present a future outlook.
