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
