Objective
The project's primary aim is to investigate the system and component aspects needed to extend the wavelength range of optical single mode fibre communication from the present 1300 to 1600 nm to a wider range extending from about 800 to 1600 nm.
The investigation will cover several possible types of fibre which could support high speed transmission in the extended wavelength range:
- one candidate is the standard single mode fibre with special precautions to prevent effects of higher order modes in couplers, connectors and when coupling in and out of the fibre,
- another candidate could be a new type of fibre which is truly single moded and applicable over the full 800 to 1600 nm range. Such a fibre may have a more complex index profile than the standard single mode fibre and, consequently, also potential higher cost and attenuation.
The objective is to study ways of improving the overall cost/performance figures of optical fibre communication in local networks by utilizing appropriate ESM techniques.
The basis for subsequent specifications and international standards will be elaborated. The investigation will include the following topics: ESM-fibre principles, ESM-transmission and switching concepts, network topologies, evolutionary aspects, sources and detectors, ESM-fibre joining and cabling aspects, fibre-based couplers, including wavelength multiplexers, implications for the interfaces between local and long distance networks.
