“…One of the most useful ways to achieve this capacity upgrade is to increase the bit rate, while another is to reduce the channel spacing. Since the modulation bandwidth of an RSOA is known to be about 2 GHz, several works related to the operation of a greater than 2 Gb∕s have already been presented [13]. However, the relative intensity noise (RIN) degradation caused by narrow-band spectral filtering severely impairs the transmission performance concerning the decrease of channel spacing in a spectral slicing WDM-PON [14].…”

We experimentally investigated the 1.25 Gb∕s operation of a spectrally sliced amplified spontaneous emission (ASE) injected reflective semiconductor optical amplifier (RSOA) with 50 GHz channel spacing using an injection current adjustment, dispersion management, and the use of an optical receiver with an optimized decision threshold level. We mitigated the relative intensity noise (RIN) degradation caused by post-filtering through the injection current adjustment, and also alleviated the dispersion-induced RIN degradation with the help of the dispersion management method. Finally, the use of an optical receiver with an optimized decision threshold level eliminated error floors, which were attributed to an unequal noise distribution between the mark level and the space level. We also successfully demonstrated a loop-back wavelength division multiplexing-passive optical network (WDM-PON) with a 100 Gb∕s (80 × 1.25 Gb∕s) capacity using a spectrally sliced ASE injected RSOA by means of the three aforementioned methods. We also analyzed and examined the transmission impairments, such as the dispersion penalty and back-reflection induced penalty, in a 1.25 Gb∕s bidirectional WDM-PON based on an RSOA with 50 GHz channel spacing.

“…respectively. The spectrum of the coherent light source is not expanded after passing through the SOA, which is different from that of the incoherent light source using the spectrum slicing method [12][13][14].…”

“…This fact makes colorless WDM PON systems uneconomical when supporting a large number of ONUs. Furthermore, for reusing downstream light sources by employing gain saturated SOA, we discover that the residual power of downstream signal unexpectedly springs back after transmissions, causing severe interference and performance degradation to the upstream signal [11][12][13][14]. As a result, these colorless systems [8,10] can only support limited data rates for upstream transmissions.…”

In this paper, we propose a two-tiered colorless WDM-OFDMA PON system architecture that draws strengths from each individual WDM and OFDM PON systems. Specifically, the two-tiered architecture enables a colorless transceiver to be shared by a group of ONUs, resulting in drastic reduction of the system cost. For achieving colorlessness via reusing downstream light sources, we discover the residual power of downstream signal unexpectedly springs back after transmissions, causing severe interference to the upstream signal, and thus limiting the data rate of the upstream signal. We devise a method of adopting a common dispersion compensation module at OLT to reduce the residual power over all wavelengths. Experimental results show that, with an improvement of upstream signal's SNR up to 10 dB, the system successfully achieves 20-Gb/s bidirectional OFDM-signal transmissions on the same wavelength over a 20-km SMF.
