Polymer Optical Fiber (POF) for In-House-Networks using Lower Girth Transmission System

The Plastic Optical Fiber strives to actively promote the proliferation of Polymer Optical Fiber (POF) systems serving both data communication and non-data markets.  Single mode silica optical fiber has already established as undisputable position in core telecommunication networks and has reached Tbits/s throughputs. When optical fiber approaches the user's residence, even enters his home, the costs of installing and maintain become even more important. The Use of POF will be an attractive solution for future broadband CPN. Present systems work with 650 nm sources. In This Research I have proposed the use of 520 nm InGaN LED and will show advantages and open problems. The paper will present the present status of POF systems, based on 650 nm components. The ATM Forum specifies a link with a capacity of 155 Mbps and 50 m reach. For a number of applications it would be helpful to improve this system in the direction of a longer reach and/or more system margin in the power budget

Recent Results From the EU POF-PLUS Project: Multi-Gigabit Transmission Over 1 mm Core Diameter Plastic Optical Fibers

Recent activity to achieve multi-gigabit transmission over 1 mm core diameter graded-index and step-index plastic optical fibers for distances up to 50 meters is reported in this paper. By employing a simple intensity-modulated direct-detection system with pulse amplitude or digital multi-tone modulation techniques, low-cost transceivers and easy to install large-core POFs, it is demonstrated that multi-gigabit transmission up to 10 Gbit/s over 1-mm core diameter POF infrastructure is feasible. The results presented in this paper were obtained in the EU FP7 POF-PLUS project, which focused on applications in different scenarios, such as in next-generation in-building residential networks and in datacom applications

SI-POF supporting power-over-fiber in multi-Gbit/s transmission for in-home networks

We propose the integration of power-over-fiber (PoF) in home networks with multi Gbit/s data transmission based on wavelength-division-multiplexing (WDM) in step-index plastic optical fibers (SI-POF). Different powering architectures are described. The efficiencies of different components are discussed to address the maximum remote energy that can be delivered. Experimental results show the ability of the system to deliver several mW of optical power with negligible data signal quality degradation and with BER of 1 × 10¿10. The potential of utilizing PoF in combination with low-loss WDM-POF to optically powering multiple devices for specific in-home applications and IoT ecosystems is discussed. A PoF scalability analysis is detailed.This work was supported in part by the Spanish Ministry of Science, Innovation and Universities under Grant RTI2018-094669-B-C3; in part by the Directorate for Research and Innovation at Madrid region under Grant Y2018/EMT-4892; and in part by the H2020 European Union 5G PPP Bluespace project under Grant n°.762055

Planar Large Core Polymer Optical 1x2 and 1x4 Splitters Connectable to Plastic Optical Fiber

We report about new approach to design and fabricate multimode 1 x 2 and 1 x 4 Y optical planar power splitter suitable for low-cost short distance optical network. The splitters were designed by beam propagation method using BeamPROP™ software. The dimensions of the splitters were optimized for connecting standard plastic optical fibre with 1 mm diameter. New Norland Optical Adhesives 1625 glues were used as optical waveguide layers and the design structures were completed by CNC engraving on poly(methyl methacrylate) substrate. The best parameters that were achieved with 1x2 splitter were insertion loss around 4.1dB at 650 nm and the coupling ratio 52:48; the best one of the 1x4 splitters had at 650 nm insertion loss around 17.6 dB

Discrete Multitone Modulation for Maximizing Transmission Rate in Step-Index Plastic Optical Fibres

The use of standard 1-mm core-diameter step-index plastic optical fiber (SI-POF) has so far been mainly limited to distances of up to 100 m and bit-rates in the order of 100 Mbit/s. By use of digital signal processing, transmission performance of such optical links can be improved. Among the different technical solutions proposed, a promising one is based on the use of discrete multitone (DMT) modulation, directly applied to intensity-modulated, direct detection (IM/DD) SI-POF links. This paper presents an overview of DMT over SI-POF and demonstrates how DMT can be used to improve transmission rate in such IM/DD systems. The achievable capacity of an SI-POF channel is first analyzed theoretically and then validated by experimental results. Additionally, first experimental demonstrations of a real-time DMT over SI-POF system are presented and discusse
