Plastic Optical Fiber Based In Home Optical Networks
Optical communication systems, after having conquered long-haul and medium-distance connections, are currently migrating into short-range communication applications. Optical solutionsoffer the possibility of high-speed data transfer for professional as well as consumer applications. As the main driver, broadband access networks, and in particular fiber to the home FTTH , are offering abundantly available bandwidth in the local loop with high quality of services.
High-end service bundles readily offer Gb/s, Plastic Optical Fiber Based In Home Optical Networks and, given a historically sustained annual increase of around percent, it can be expected that Gb/s to theuser premises will be a commodity service in, Plastic Optical Fiber Based In Home Optical Networks while in high-end rates up to Gb/s could appear for early adopters. Under such broadband connectivity conditions, the home network must not represent the bottleneck for the Internet service provider ISP to deliver its services to the consumer.
Plastic Optical Fiber Based In Home Optical Network
Plastic Optical Fiber Based In Home Optical Networks This is especially true when considering the expected evolution for services such as the introduction of high definition HD IPTV, Plastic Optical Fiber Based In Home Optical Networks multi-room/multivision configuration, using different channels seen in different rooms with up to three set-top boxes STBs , and high-quality video communication via the TV set. In order to address these concerns, the transport medium present inside the user’s premises must provide large bandwidth, and low latency with low packet error rates. In , existing in-home networking technologies twisted pair, coax, Cat, powerline, wireless, and plastic optical fiber POF were evaluated. The coppersolution and wireless physical layer (PHY)cannot meet such high capacity and quality of service QoS requirements .
Plastic Optical Fiber Based In Home Optical Networks Link reliability is often the main issue, leading to increased service calls and thus higher operational expenses for the operator. Plastic Optical Fiber Based In Home Optical Networks It is likely that the user is required to modify or replace the installed cable infrastructure. Moreover, the terminal placement is not flexible, meaning that a single connectivity point exists in the home. Plastic Optical Fiber Based In Home Optical Networks Fiber in the Home FITH offers exciting features to address broadband high-speed connectivity in the user premises, so it has great potential to be considered as a future-proof solution. In this work, we focus on the state of the art in FITH based on large-core Polymethylmethacrylate PMMA POF. The article is organized as follows. The main advantages of large-core POF-based in-home network solutions are summarized. An economic estimation and comparison among Cat-5, silica fiber, and POF solutions is presented. Then an overview of state-of-the-art POF technologies, including optoelectronic devices, the latest transmission achievements, and the standardization status, is presented. From research to deployment, the world’s first service trial of International Telecommunication Union Telecommunication Standards Sector ITU-T G.hn over POF is outlined. Finally, conclusions are drawn. A number of topologies for the indoor wired backbone network may be considered point-to-point PP , bus, tree, and hybrid forms thereof. In the PP topology , individual cables run to each room from the residential gateway RG interfaces the access network with in-building networks and performs local functions. This topology allows easy upgrading and maintenance per room, but requires a high amount of cabling with associated installation efforts and duct congestion issues, particularly in larger buildings. The bus and tree topologies are point-to-multipoint P MP topologies, in which cables are shared among rooms, and the number of cables to the RG is reduced. The bus solution is the most cable-lean, but requires many hub nodes to connect each room. The tree solution has a switch node per floor.
