“…Alternatively, RSOA based self-seeded WDM-PON US transmitters were suggested to eliminate the external seeding source. Initial implementations of self-seeded sources employed feedback mechanisms including fiber Bragg gratings, [4], [5]. Unfortunately, these methods require separate and accurately tuned wavelength selective components in every optical network unit (ONU), thus preventing colorless operation and increasing the complexity and cost.…”

Reflective semiconductor optical amplifier (RSOA) fiber cavity lasers are attractive colorless, self-seeded, self-tuning, and directly modulatable sources for passive optical networks (PONs). They comprise of an RSOA in the optical network unit as the active element, a distribution fiber as the laser cavity, a waveguide grating router, and a common reflective mirror with the latter two positioned at the remote node. In this paper, we introduce a model and perform simulations to elucidate the recently discovered successful operation of this new PON source. The results are in agreement with experiments; the formation of a narrow laser spectrum with a relatively constant output power is seen despite a relatively broad passband window of the waveguide grating router. We further study mode competition and mode partition noise. It is shown that proper chromatic dispersion management can overcome mode partition noise limitations. The quality of the RSOA fiber cavity laser does not degrade when being directly modulated and as a result these highly multimode lasers offer an economic way to transport Gbit/s upstream data over kilometers of fiber in a wavelength division multiplexing-PON.

“…Hybrid orthogonal modulation formats are also used to differentiate the private and public communications [38,43,44]. In addition, specific sub-carrier bands [29,30] or time slots [26,27,34,35,37] can be assigned to the different types of connections.…”

“…The wavelength-selective reflection using fiber Bragg grating (FBG) is a good candidate for establishing all-optical VPN with specific wavelengths [24,29,30,[36][37][38][42][43][44]. A star-coupler can directly route the private traffic to the ONUs with relatively low insertion loss [25][26][27][28][29][30][31][33][34][35]. A cyclic N×N array waveguide grating (AWG) can efficiently route the communications among ONUs in a WDM-PON [39][40][41].…”

“…Upstream traffic is transported to the CO through distribution fiber 1 and feeder fiber while the LAN traffic transmission is performed using distribution fiber 1 to the SC and broadcast to all ONUs through distribution fiber 2. It should be noted that as the distribution part of the PON is short in dis- Figure 13 Upstream access and LAN emulation using a single RSOA, whereby traffic transport is performed by the self-seeding the RSOA using FBGs placed at the ONUs [35].…”

We review recent progress on all-optical virtualprivate-network (VPN) schemes in passive optical networks (PONs). PON is a promising candidate in future access areas to provide broadband services with low cost. With all-optical virtual private network (VPN) function, PON can support efficient internetworking among end users with dedicated optical channels, thus enabling guaranteed bandwidth and enhanced security at the physical layer. Here, we discuss and compare existing schemes of all-optical VPNs in time-division-multiplexed (TDM) PONs, and also recently proposed schemes for deployment in wavelength-division-multiplexed (WDM) PONs and two-stage TDM/WDM PONs.
