“…The SCA configuration have shown to be tolerant against non-linearities caused in WDM transmission systems. 13 To our best of knowledge the budget extension for 60 Gbit/s has never been reported before in the literature. The scheme is packed and reduced to have minimum number optical components, this makes the setup attractive for NG-PON.…”

This paper shows optical power extension techniques for 10 Gbit/s per λ channel for WDM-PON DPSK systems. The scheme is based on semiconductor optical amplifiers. We present 56.5 dB total optical power budget enhancement using our configuration for the downstream scenario. The setup is cost effective in terms of optical components. Only one DLI (Delay Line Interferometer) is used to convert DPSK signals to OOK. We present experimentally as well as through simulations that our scheme has better performance than a single SOA as a power budget extender.

The integration of ultra-wideband (UWB)-over-fiber into passive optical network (PON) is of great interest as it benefits the high bandwidth capability from optical network technologies and the high flexibility from wireless network technologies. The later can only be done with a reasonable cost when a universal optical transmitter, which is capable of generation both UWB and PON signals, is available. Direct modulation of semiconductor laser was demonstrated to be suitable for high bit-rate PON systems, however the generation of UWB signals by this technique is still challenging. Using the chirp properties of directly modulated semiconductor lasers, UWB signals are generated. Different UWB signal waveforms and polarities are obtained. The received electrical spectra conform to the requirements of indoor UWB systems.

“…The optical amplification can be inserted in hybrid WDM/TDM NG-PONs at RN (as in Figure 1) [5]. This paper is based on previous work [8], [9] on efficient SOA-based amplification techniques in NG-PONs. The proposed extension scheme is not only limited to the hybrid WDM/TDM architecture in Figure 1, but also different configurations such as hybrid TWDM NG-PON2 [10] can utilize this technique.…”

Abstract-Passive Optical Network is designed such that it meets the requirements of NG-PON. According to FSAN, the Time and Wave Length Division Multiplexing (TWDM) is chosen as the best solution to implement NG-PON. EDFA amplifier is used in the system to compensate the effects of degraded signal in both the directions upstream/ Downstream (US/DS). It is observed that system can transmit over 40 Km SMF with acceptable BER. NGPONs also remarkably improves increase in the users to 2400 downstream and 512 upstream. It is observed that with increase of link length the value of Q-factor decreases and there is increase in the BER. Capacity enhancement, high data rate and large bandwidth can be achieved by using advanced modulation formats between efficient techniques.
