“…Moreover, the SPA has proved highly effective at obtaining agreement with measured results [13] and the results correspond well with those using a Fourier approach with chi square statistics [14]. In addition, measured results in [15] display power penalties of 1-2 dB consistent with the SPA results rather than the large penalties predicted by the GA. Figure 3 shows the optimum receiver sensitivity and its corresponding optical bandwidth as a function of the normalized distance. The figure also illustrates the increasing penalty with greater transmission distance.…”

-The effect of dispersion on a spectrum-sliced WDM (SS-WDM) system with an optical preamplifier receiver is investigated for the first time. A theoretical model based on the statistics of both the incoherent source emission and the fiber dispersion is developed and used to obtain the bit error rate (BER). This model improves understanding of the spectral slicing method in a realistic situation where dispersion significantly impacts the transmission prior to arrival at the optical preamplifier. The optically preamplified receiver delivers a system of 2.5Gbps with at least twice the transmission capacity of a one with a pin diode receiver. This arises because the optimum slice width is decreased to ~0.3 nm allowing over 110 WDM channels. As a further benefit, a sensitivity improvement of 8.75 dB offers a superior power budget in comparison with the pin diode receiver, and the power efficiency can be improved by over 8dB. The results are obtained using the saddlepoint approximation and compared to the customary Gaussian approximation. The latter is found to be reasonably accurate in predicting the optimum bandwidth but conservative in sensitivity predictions.

“…The input power for the externally seeded transmitters is also set for maximum performance. Here we only give the operation points that have been selected while one can find more details on finding the ideal operation points of an ASE spectrum-sliced transmitter in [44,45] and the externally seeded transmitter [25,46].…”

Bit- and Power-Loading—A Comparative Study on Maximizing the Capacity of RSOA Based Colorless DMT Transmitters

Abstract:We present a comparative study of the capacity increase brought by bit-and power-loading discrete multi-tone (DMT) modulation for low-cost colorless transmitters. Three interesting reflective semiconductor optical amplifier (RSOA) based colorless transmitter configurations are compared: First, an amplified spontaneous emission (ASE) spectrum-sliced source; second, a self-seeded RSOA fiber cavity laser (FCL) and third, an externally seeded RSOA. With bit-and power-loaded DMT, we report record high line rates of 6.25, 20.1 and 30.7 Gbit/s and line rates of 4.17, 10.1 and 24.5 Gbit/s in a back-to-back and in a 25 km nonzero dispersion shifted fiber (NZDSF) transmission experiments for the three transmitter configurations, respectively. In all the experiments, BER (bit error ratios) below an FEC (forward error correction) limit of 7.5 × 10 −3 were achieved.

“…For the case of a 10 Gb/s signal, we have estimated that the equivalent optical bandwidth of a BLS seeded R-EAM source should be increased to be wider than 10 nm for the error-free transmission. This estimation is based on the fact that the signal-to-noise ratio (SNR) of a BLS based optical source is determined by the ratio of optical bandwidth and electrical bandwidth [8][9][10]. However, in our previous study, we used only a few different optical bandwidths of BLS seeded R-EAM optical source, due to the limited availability of an optical bandpass filter (OBPF) at that time.…”

The impact of equivalent optical bandwidth on the performance of a system using a reflective electroabsorption modulator (R-EAM) based optical source has been experimentally evaluated with signals operating at 2.5 Gb/s and beyond. The equivalent optical bandwidth of our source with a broadband seed light was simply adjusted by using a bandwidth tunable optical filter. From the measurements, we have estimated the required equivalent optical bandwidth of our source for an error-free transmission (@ bit-error-rate of 10 .
