“…These types of systems have emerged to handle large sets of data over the optical fibre systems by which more sophisticated protocols can better handle the synchronisation. Some of the advantages of the OTN technology are the ultra-capacity that comes with high accuracy over DWDM lines and the transparent transport of user signals which is attributable to the asynchronous mapping and demapping of the signals [60]. The mixing of synchronous signals with different clock sources, as well as the asynchronous signals, can be carried out on a common wavelength in this technology.…”

A smart grid provides a bidirectional flow of electricity and information whilst ensuring wellbalanced electricity supply and demand. The key enabler for the smart grid is its robust communication infrastructure. Choosing the best communication technology for the smart grid is crucial as it involves a mixture of critical and non-critical traffic. This study provides a comprehensive review on smart grid communication and its possible solutions for a reliable two-way communication toward supporting diversified power grid applications. Existing networking methods along with their advantages and weaknesses are highlighted for future research directions. The communication network architecture in the smart grid, with details on each networking technology, switching methods and medium for data communication, is critically reviewed to identify the existing research gaps. A discussion on issues and challenges encountered in smart grid communication for current implementation is highlighted together with the recommendations for further improvement. Overall, the highlighted issues and recommendations from this study are useful to researchers, technology providers and industries to develop new communication technologies for the smart grid that will provide reliable, robust, and suitable two-way communication in the future.

“…OSU attached with tributary port number (TPN) can dynamically identifying the corresponding relationship between OSU and services. Moreover, as OSU is compatible with smaller service bandwidth, it can afford over 1000 ODU connections, while traditional OTN supports merely 80 connections [2]. In addition, it is demanded that the bandwidth upgrade is imperceptible in case of private lines application, so that OSU should be capable of switching bandwidth simply without affecting the services.…”

“…OTN consists of a set of powerful technologies that offer high-speed traffic transport, network management and supervisory, and service grooming and switching. OTN technologies and standards keep continuous innovation, and evolve from supporting 2.5 Gb/s service since around year 2000 to beyond 100 Gb/s recently [1,2]. In addition to bit rate upgrade, OTN technologies are also being deployed from backbone network to metro network and even to metro edge, so that OTN equipments are getting closer and closer to end users while more and more new service demands and technical requirements are emerging.…”

With the development of transmission technologies, optical transport network (OTN) has evolved from a digital encapsulation technology to a network technology that supports multi-service transport. As the OTN gradually expands to the edge of the metropolitan area network (MAN) and enterprise users have higher quality requirements on bandwidth and service security, more and more private line services are provided via OTN network. Therefore, the OTN container is transformed from an optical data unit (ODU) to an optical service unit (OSU). The OTN industry has studied several OSU technologies to fit the development trends of NG OTN, aiming at transporting 2 Mbit/s to 100 Gbit/s constant bit rate (CBR) services and Ethernet services with high efficiency and more flexibilities, as well as reducing OTN network deployment and operation and maintenance (O&M) costs. In this work, several key technologies in NG OTN are introduced including NG OTN technical architecture, OSU frame format, client mapping and OSU multiplexing. Based on these technologies, we (China Mobile) took the lead in conducting the industry's first NG OTN test in Qingdao, which verified the service transport capability and lower latency performance of OSUs and promoted the maturity of the NG OTN industry chain.
