In this paper, we propose and test experimentally a real-time 10 Gbps polarization independent quasicoherent receiver for NG-PON2 access networks. The proposed 10 Gbps quasicoherent receiver exhibits a sensitivity of -35.2 dBm after 40 km SSMF transmission with a commercial generic EML as transmitter. This sensitivity means a 14.9 dB improvement over a direct detection scheme with a photodiode after 40 km SSMF transmission. Therefore, the use of the proposed 10 Gbps quasicoherent receiver with the tested EML will provide a power budget of 35.64 dB (class E2) and a splitting ratio of 128 after the 40 km SSMF transmission. Finally, the proposed 10 Gbps quasicoherent receiver allows a colorless and optical filterless operation because wavelength selection is done by tuning the local oscillator wavelength and using electrical intermediate frequency filtering.

“…Moreover, to improve the system performance, the concepts of COH systems have been adapted to the direct detection schemes in some research efforts. For instance, various architectures have been proposed for direct phase modulation of the transmitter lasers [32], while a variety of cost-effective Co-Rx configurations have also been proposed [33,34]. Furthermore, a review and comparison of different optical SCOH subsystems with different channel linearization technologies and DSPs have been presented [9,[11][12][13][14]19,26,[33][34][35][36][37][38].…”

This paper reviews recent progress on different high-speed optical short- and medium-reach transmission systems. Furthermore, a comprehensive tutorial on high-performance, low-cost, and advanced optical transceiver (TRx) paradigms is presented. In this context, recent advances in high-performance digital signal processing algorithms and innovative optoelectronic components are extensively discussed. Moreover, based on the growing increase in the dynamic environment and the heterogeneous nature of different applications and services to be supported by the systems, we discuss the reconfigurable and sliceable TRxs that can be employed. The associated technical challenges of various system algorithms are reviewed, and we proffer viable solutions to address them.

“…In order to address these requirements, the coherent technologies have been proposed as the key enabler [102,103]. In these recent years, cost-effective transceivers based on directly and externally modulated lasers has been studied and proposed in order to fulfill the sensitivity and data rate requirements [104][105][106][107]. In addition, simplified digital signal processing for optical coherent received signals has been researched and code modulation for the cost-effective transceivers has been developed [108][109][110][111][112].…”

Passive optical networks (PONs) are telecommunication networks that provide services to users by no active elements. Only passive elements are used in the network to transmit the information and signals between users as well as between users and the companies operating the telecommunication networks.PONhave evolved from their infancy as fine and economical ideas, toward a long‐term, reliable, and cost‐effective technical solutions for providing access to most users to high‐speed Internet by Fiber‐to‐the‐Home (and similar) solutions.PONare still evolving, providing the base of multiple standardized networks and in combination with different technologies are growing into metropolitan networks and extensions of mobile communications.Herein, we overview the state of the art of passive optical networks as well as their basic concepts. This work is divided into four sections: In Section 1, we give a summary of the main concepts of passive optical networks. Sections 2 and 3 introduce the most important features ofITU‐TRecommendations andIEEEStandards for passive access networks, respectively. Finally, Section 4 concludes the article with an overview on the future trends ofPONsfor access networks.
