The use of polymer optical fibers for in-house-networks, advantages of 520 nm LED transmission systems

The use of polymer optical fibre (POF) will be an attractive solution for future broadband CPN. Present systems work with 650 nm sources. This paper propose the use of 520 nm InGaN LED and will show advantages and open problems. We 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.
