“…Dense -WDM-PON (DWDM-PON) is an evolution of WDM-PON were the channel spacing is considerable reduced from tenths of nm [22] to 0.8nm or 1.6nm [23], offering thereby better spectral efficiency. Also it has a longer reach, between 70 and 135 km [24]. Finally, Coherent ultra-dense Wavelength Division Multiplexing Passive Optical Networks (UDWDM-PON) allows a more efficient use of the optic spectrum, introducing a new concept: WTTU wavelength-to-the-user, through decreasing the channel spacing as low as 2-3 GHz [25].…”

Future autonomous vehicle will require a high level of computation, communication, sensing and fast response actuation. Communication among vehicles, and vehicles to infrastructure, accessing to remote systems and services will help to reduce other requirements in computation and sensing. This paper revise current state of the art of wireless technologies as: LTE, LTE-A Pro, IEEE802.11p and 5G, as well as optical fiber access technologies as: TDM, WDM, D-WDM and uD-WDM, for the different communications requirements in diverse scenarios as: Vehicle-to-Infrastructure (V2I), Vehicle-to-Vehicle (V2V), Vehicle-to-Pedestrian (V2P) and Vehicle-to-Network (V2N).

“…Figure 1(a) shows the model of a typical PON using optical fiber links, which consists of optical network units (ONUs), a passive splitter at the remote node (RN), and an optical line terminal (OLT). Typically, PON can reach the distance of up to 20 km, and it is capable of delivering upstream to 1.2 Gbps and 2.4 Gbps downstream to the port with current standards [26]. As the next step in fiber access evolution, the ITU-T is defining the second next generation PON (NG-PON2), which is primarily based on time and wavelength division multiplexing (TWDM) since it is most compatible with the high volume residential application.…”

This paper newly proposes and theoretically analyzes the performance of multi-hop free-space optical (FSO) systems employing optical amplify-and-forward (OAF) relaying technique and wavelength division multiplexing (WDM). The proposed system can provide a low cost, low latency, high flexibility, and large bandwidth access network for multiple users in areas where installation of optical fiber is unfavorable. In WDM/FSO systems, WDM channels suffer from the interchannel crosstalk while FSO channels can be severely affected by the atmospheric turbulence. These impairments together with the accumulation of background and amplifying noises over multiple relays significantly degrade the overall system performance. To deal with this problem, the use of the M-ary pulse position modulation (M-PPM) together with the OAF relaying technique is advocated as a powerful remedy to mitigate the effects of atmospheric turbulence. For the performance analysis, we use a realistic model of Gaussian pulse propagation to investigate major atmospheric effects, including signal turbulence and pulse broadening. We qualitatively discuss the impact of various system parameters, including the required average transmitted powers per information bit corresponding to specific values of bit error rate (BER), transmission distance, number of relays, and turbulence strength. Our numerical results are also thoroughly validated by Monte-Carlo (M-C) simulations.

“…The wavelength‐division‐multiplexed‐passive optical network is a hopeful solution for access networks due to its large capacity and upgradability . In this scenario, the wavelength reuse is useful to enhance the system capacity—the same optical carrier is so used for both downstream and upstream channels .…”

Propagation in a 25‐km fiber link with wavelength reuse based on amplitude modulation erasure by deep saturated ultralong semiconductor optical amplifier is demonstrated up to 12.5 Gb/s. Downstream signals with modulation extinction ratio (ER) up to 10 dB were tested in links with standard and dispersion compensated fibers. The impact of bit rate and input ER over the wavelength reuse performance is investigated, including tests at diverse wavelengths to induce residual dispersion impairments. Despite the inherent spectral broadening occurring in the erasure process the upstream signals have good quality even after dispersive fiber links, as evidenced by BER characterization. © 2015 Wiley Periodicals, Inc.
