OCCFIBER.COM 2 WHAT IS PASSIVE OPTICAL LAN? Passive Optical LAN technology is a point-to-multi-point architecture that provides the capability to securely deliver voice, data, and IP video and/or broadband video over a single strand of optical fiber. This architecture is based upon carrier-grade passive optical network technology that has been reliably utilized in fiber-to-the-home deployments for many years, as well as hospitality, residential, and commerical applications. POL is comprised of two key network electronic components: 1) Optical Line Terminal (OLT) and 2) the Optical Network Terminal (ONT). The OLT is normally located in the equipment room. It aggregates optical traffic and provides the interface to edge IP network switches and routers. The ONT is normally located at the user's work station or zone enclosure and de-multiplexes the fiber optic signal into its component parts (i.e., voice/data/video) and outputs these signals on copper ports (i.e., RJ45). CORE ROUTER ONT VOICE 1X32 ONT DATA OLT ONT SWITCHED VIDEO The OCC POL Solution ensures network traffic is transported between these devices over a passive optical fiber infrastructure that generally consists of the following components: » Pre-terminated single-mode optical fiber cable » Passive optical splitters » Fiber adapter plates and cassette modules » Fiber enclosures (rack/wall/ceiling mount) » Faceplates/surface mount enclosures/pass-through couplers 3 OCCFIBER.COM CENTRALIZED SPLIT ARCHITECTURE In this architecture, the splitters are located near the OLT or other active hardware. Individual simplex fiber optic cables connect this centralized location to each ONT throughout ONT the building. The centralized split architecture works well in ONT retrofit installations, where a telecommunications room or rack ONT is already located near the users and is being re-used as a ONT telecommunications room.

  • Passive Optical Components and Their Applications to FTTH Networks
    SPECIAL Passive Optical Components and Their Applications to FTTH Networks Hiroo KANAMORI This paper describes technologies related to passive optical components such as fused fiber couplers, optical filters, splitters and fiber gratings. These components have been actively deployed in FTTH (Fiber to the Home) networks. A splitter connects transmission equipment at a central office to a plurality of users, leading to economical PDS (Passive Double Star) networks. A splitter with a directional coupler circuit or an optical filter enables multiplexing of video signals. A fiber grating external cavity laser diode is suitable as an OTDR (Optical Time Domain Reflectometer) light source. The light from OTDR is coupled to the main route through such a highly integrated device as a PLC coupler or a tape fiber fused coupler to be reflected at a terminal filter that employs an optical connector embedded with a chirped fiber grating. Keywords: FTTH, fused fiber coupler, splitter, fiber grating, PLC 1. Introduction Optical Fiber Optical fiber communication has brought us a new In - ternet society. In Japan, FTTH (Fiber to the Home) net - works, in which optical fibers are installed directly to users’ homes, have been so popular that the number of contrac - tors for FTTH service has exceeded fifteen millions as of May 2010. “Optical fiber,” “light source,” and “photo de - tector” are said to be three key elements of optical fiber Micro Torch communication. It should be noted, however, that various Fig. 1. Fiber Fused Coupler kinds of optical components and related technologies, be - sides those three elements, have contributed to the evolu - tion of optical communication, improving functionalities, with further propagation length.

  • Design of Wireless Passive Optical Communication Network Based on Fusion of Fibre to the Home Architecture
    Wireless Pers Commun DOI 10.1007/s11277-017-4354-5 Design of Wireless Passive Optical Communication Network Based On Fusion of Fibre to the Home Architecture 1 2 1 S. Mary Praveena • Ila. Vennila • R. Vaishnavi Ó Springer Science+Business Media New York 2017 Abstract The steady increase in the demand for broadband services and the consequent increase in the volume of generated traffic in our communication networks have motivated the need to implement next generation networks in our territories. Optical Fibre cable is used as media to design long/short network and it supports high bandwidth in Gigabits per second speed. Earlier OFC is used to connect the long distance places and called Optical Transport Network and presently used even in local/Access network called Optical Access Network. In present environment data to be transmitted is so high due to growth in internet. Successful transmission of such a huge bandwidth is big challenging job for long distance network designer. All customers require the QOS and they are interested to make SLA for their service to be obtained from Service provider. ISP should design their network to support the customer requirement suitably otherwise ISP cannot survive in this competitive environment. This paper aims to explain the design and planning of a passive optical network based fiber to the home architecture. The main idea of this paper is to build a fabricated environment that allows us to analyse the depth on FTTx networks and decide which is the most preferable option for this environment. Finally, the simulation software that meets the design requirements will be chosen, the design of passive optical network will be made and the results justify that the network is more viable and can be implemented in a real time.

Received: 2 June 2020; Accepted: 26 June 2020 ; Published: 1 July 2020 Abstract: For many years, passive optical networks (PONs) have received a considerable amount of attraction regarding their potential for providing broadband connectivity to almost every citizen, especially in remote areas where fiber optics can attract people to populate regions that have been abandoned. Error-free connectivity without dropouts can offer new opportunities to communicate, earn money and enjoy cultural events. Transmission speeds are multigigabit with distances of a few tens of kilometers; these specifications were previously reserved for high-speed and long-haul backbone networks. PONs can also support a new class of applications, such as accurate time transfer or distributed fiber sensing and follow new trends in open networking. An outline of past and current standards and standards that have been proposed for the latest generation of multigigabit PONs is provided.
