For a fiber-optic M-ary QAM-SCM-IM/DD system, the receiver requires high carrier-to-noise ratio to get a reasonable performance. A performance analysis of the M-ary QAM-SCM-IM/DD system employing the optical amplifier is presented. We analyze the advantages of using the optical amplifier in terms of carrier-to-noise ratio, receiver sensitivity, and the channel transport capability. Then the benefits of applying error control code are also investigated. It is found that coding can increase the total channel number and eliminate error floor under a given bit error rate and receiver sensitivity. In addition, the optimal modulation index per channel is derived.

“…Amfilification serves to overcome splitting losses associated with distribution fan out as well as coupler, tap, and line losses [4, 51. On the other hand, for higher optical amplifier gains, the spontaneous emission noise of the amplification process is a serious impairment, so that there is concern about a role for system performance [6]. In this Letter, we investigate the impact of spontaneous emission noise of optical amplifiers on the coherent optical frequency-shift-keying (FSK) SCM systems.…”

Analysis on the channel capacity of a coherent optical subcarrier multiplexing system using optical amplifiers is presented. The performance criterion, that is, the channel transport capability N, is derived in terms of carrier‐to‐noise ratio, input optical power, and optical amplifier gain. It is found that when the gain of the optical amplifier is large, the spontaneous emission noise limits the number of channels that can be transmitted in this system. As an example, when the gain is well above 20 dB and input optical power is −28 dBm, the maximum value of N is 46. In addition, the optimum phase modulation index is also presented. © 1995 John Wiley & Sons, Inc.
