“…REE-SPACE optical (FSO) communications has a great opportunity to be expanded for applications to support many platforms of telecommunication systems such as high-altitude, satellite, terrestrial, and mobile terminal [1][2][3][4]. To the best of our knowledge, FSO also has been investigated intensively for the application in deep-space communications, underwatercommunications, and Li-Fi [5][6][7]. However, with the potential of rate capacity in the order of a gigabyte or terabyte for transmitting data or signals, FSO has faced a major problem in penetrating the barrier of atmospheric turbulence effects in order to reach the long distance of optical propagation.…”

The performance of free-space optical (FSO) communications that using an optical amplifier (OA) in the scheme of an amplify-received (AR)-relaying has a major drawback in the detection of input signal quality under the effects of turbulence. As an OA is based on a fiber-detection (FD) method to receive and delivers a signal at the amplification process stage, there is an opportunity to implement an optical spatial filter (OSF) to improve the quality of an input signal. In this paper, as the continuation of previous work on the direct-detection, the OSF is applied on the AR-relaying. The novelty proposed in this work is the improvement of FD method where the OSF is designed as the integration of cone reflector, pinhole and multi-mode fiber with an OA. The OSF produces an optical signal, the input of the OA, which minimizes the effects of turbulence, background noise and signal fluctuation. Thus, OA in AR-relaying produces signal output with high power and rise up below threshold level. Additionally, an OSF with a lower pinhole diameter produces the best quality of the signal spectral to be delivered into an EDFA. Through this implementation, the performance of optical relaying on FSO can be significantly improved.
