“…Passive Optical Networks (PON) with a signal distribution assisted by Wavelength Division Multiplexing (WDM) seem to be good candidates [1]. However, there are several requirements for cost-effectiveness, such as scalability, robustness and a completely passive distribution network without active components.…”

Optical Network Units for Next-Generation Passive Optical Networks with wavelength reuse are investigated for asymmetrical 2.5G/1.25G and symmetrical 10G/10G down-and upstream data rates. The transmission performance was enhanced by a feed-forward cancellation circuitry adapted to an RSOA and an REAM used as remodulator. The range of downstream extinction ratios for error-free upstream transmission at BER of 10 -10 was extended from 3 to 4 dB for the RSOA-based ONU and from 1.5 to 3 dB for the REAM-based ONU.

We propose a scheme for mitigating Rayleigh backscattering noise and demodulating differential phaseshift keying (DPSK) signals in wavelength-division-multiplexed passive optical networks (WDM-PONs) with injection-locked Fabry-Perot laser diodes (FP-LDs). Signal demodulation and wavelength conversion are simultaneously realized on the basis of the frequency deviation and red shift of longitude modes in the FP-LDs. Experimental results demonstrate that the demodulation and wavelength conversion of 2.5-Gb/s DPSK signals are achieved. A power penalty of about 1.6 dB at a bit error rate of 10 −9 is measured after transmission over 25-km single mode fiber.OCIS [1,2] . These schemes include external light injection locking [3] , self-seeding [4] , and different formats of remodulation schemes [5,6] . According to present research, optical filter devices have the advantages of low cost, reliability, and manufacturability; such devices include semiconductor thin film filters [7] and computer-controlled fiber Bragg grating (FBG) [8] . In particular, these commercial devices may have very low temperature dependence, making them suitable for WDM-PON deployment. Many studies indicate that differential phase-shift keying (DPSK) signals exhibit higher receiver sensitivity and nonlinear tolerance than do traditional intensity modulation signals [9−11] ; however, a Mach-Zehnder delay interferometer (MZDI) must be deployed in each ONU, which further increases costs [12] . Interferometric crosstalk, including Rayleigh backscattering (RB) noise, can also severely degrade upstream performance when a single feeder fiber is deployed [13] . RB noise can be effectively avoided by a dual fiber transmission scheme [14] , but this scheme fails to satisfy the requirements for costeffectiveness.In this letter, we propose a DPSK demodulation and wavelength conversion scheme for WDM-PONs, in which a single commercial Fabry-Perot laser diode (FP-LD) with low-cost FBG is used. Upstream and downstream wavelengths are physically separated by wavelength conversion to mitigate reflection noise. The converted wavelength passes through a tunable optical filter (TOF) and is then split by an optical coupler. One split beam serves as the downstream receiving signal, and the other beam is launched into a reflective semiconductor optical amplifier (RSOA) as seeding light. We measure the bit error rate (BER) performance of 2.5-Gb/s downstream data with 1.25-Gb/s upstream data in single-fiber bidirectional transmission over 25-km single mode fiber (SMF). The proposed scheme effectively eliminates RB noise.As depicted in Fig. 1, the FP-LD originally self-seeds at wavelength λ * . When an external injection locking DPSK signal λ exists, the FP-LD is in a locked state at wavelength λ and the self-seeding condition at wavelength λ * is mismatched because of the red shift of cavity modes. The stable locking range of the FP-LD is only f 1 GHz. However, every phase shift in the DPSK signal produces a frequency deviation of f 2 GHz due to the sudden rise time of...

“…EPON and GPON use WDM only as a means to achieve bidirectional (upstream and downstream) transmission over a single fiber and stop short of using it as a means to increase the aggregate capacity. The use of DWDM in PONs to increase the aggregate capacity has seen significant interest in recent times [12]. The increased aggregate capacity of the network can be used for increasing the number of end users, to increase the bandwidth per user, or a judicious combination of both.…”
