In this paper, the types of modulation that support high-capacity transmission in 5G networks and beyond are discussed. Different types of digital modulation (DP-PSK , DP-QAM) and their impact on the quality of received bits are discussed. Appropriate methods are suggested for transmitting the signal for distances up to 200 km and with an acceptable number of bit errors per unit time (BER) with acceptable values of acceptable values of signal power to the noise power, (SNR) ratio . with totally transmission bit rate approximately 6.4Tb/s . So , We describe the architecture of passive optical networks with coherent wavelength division multiplexing (PONs) Which helps to support fifth generation networks and beyond.

“…Recently, with the increase in the access data traffic numerously owing to the speedy progress of cloud service, quantum computing, artificial intelligence (AI), data center, big data, 4K/8K video, online game, and 3D holographic application, the network service providers need to provide the wide network capacity, low latency, high-speed rate, and cost-effective deployment for end user [1][2][3]. Thus, the passive optical network (PON) would be the best candidate for the last mile data traffic access [4,5]. Here, the timedivision-multiplexing (TDM) and wavelength-division-multiplexing (WDM) access are currently the most used technologies.…”

In this study, we propose a new wavelength-division-multiplexing passive optical network (WDM-PON) system to support the blended fiber-free space optics (FSO) signal access. To provide the fiber and FSO traffics simultaneously, the C- and L-band channels are applied in the presented PON, respectively. Moreover, to avoid the fiber breakpoint in the fiber access traffic, the proposed WDM access architecture also can provide the self-restored mechanism by applying simple fiber routing path. In addition, the corresponding signal performances of fiber and FSO channels are also executed experimentally for demonstration.

Filterless and Compact ANy-WDM Transmission System Based on Cascaded Ring Modulators

et al. 2022

To cope with the exponential increase in internet services and corresponding data traffic, especially data centers and access networks require new high data rate transmission methods with low cost, very small package and low energy consumption. In this paper, we demonstrate a filterless, agnostic Nyquist wavelength division multiplexing (ANy-WDM) transmission system based on cascaded ring modulators and a comb source. The single ring modulator acts as a filter, filtering one of the n WDM lines, generated by the comb. The same ring modulator modulates k time division multiplexed (TDM) channels on the single wavelength. Since each WDM channel, consisting of k time domain channels, has a rectangular bandwidth, the aggregated symbol rate of the superchannel modulated by this system corresponds to the optical bandwidth of all n WDM channels together. The approach is very simple and compact. Since no optical filters, delay lines or other special photonics or high bandwidth electronics is needed, an integration into any photonics platform is straightforward. Thus, the proposed method might enable very compact, ultrahigh data rate transmission devices for future data centers and access networks.INDEX TERMS Integrated photonics, Nyquist transmission, ring modulators, WDM.
