“…1À2 and 2À2 are modulated by 10-Gb/s 2 31 À 1 pseudorandom binary sequence (PRBS) for DS transmission. Note that the extinction ratio (ER) of DS signal is set as 5-dB in order to achieve the error-free US transmission [8]. IL 2 and IL 3 inject the DS signals to the 25-km standard SMFs and direct the US signals to the corresponding RXs.…”

A novel 25-GHz-spaced dense wavelength-division multiplexing passive optical network (DWDM-PON) is proposed to improve the utilization of wavelength resource and mitigate the Rayleigh backscattering (RB) and back-reflection effects. A colorless optical network unit (ONU) is realized by remodulating the downstream (DS) signal via a gainsaturated reflective semiconductor optical amplifier (RSOA). Due to the simple interconnecting architecture at the remote node (RN), the DS and upstream (US) signals in each feed fiber (FF) are carried on different channels. Therefore, the RB and back-reflection effects are significantly reduced. The feasibility and merits of the proposed system are experimentally demonstrated with the error-free transmission of 10-Gb/s DS and 1.25-Gb/s US signals over a 25-km single-mode fiber.

“…Here the output power of RSOA is closely linked to the input power and the gain of RSOA in saturation [5]. Due to less path loss for uplink than downlink, we only discuss the power budget for downlink in detail.…”

A novel architecture of hybrid WDM/TDM-PON based on a dual-fiber ring with access-tree topology is proposed. This system can enable the network operator to easily and flexibly reconfigure wavelength resources in the light of dynamical traffic load and bandwidth requirement by using a ROADM based on WB technology at each RN. Simultaneously, this scheme is able to improve reconfiguration of network in response to the failure of some fiber by utilizing a backup feeder-fiber ring and some optical switches.

“…The first results have been proposed in [18], where the uplink data stream was reflected and modulated via the RSOA at 1.25 Gbit/s, as then further developed and investigated in several later works (e.g. [19][20][21][22]). …”
