ETSI ETR 248

This ETR describes the results of the studies of the use of single-mode fibre in the access network, referred to in this report as the Optical Access Network (OAN). It has identified a number of functions that are required and has begun to list those functions that require to be studied. There may even be a requirement not to define (standardize) some of the functions identified. Where it has been possible to provide a definition in suitable text for a function, it is given in this report. However where a definition requires further study, this is indicated accordingly. As this network may carry analogue and digital signals, this ETR describes the characteristics of an access network using monomode fibre (single mode) between the user network and the local exchange, or head end, that allows evolution from the Plain Old Telephony Service (POTS) and similar bearer services to the Broadband Integrated Services Digital Network (B-ISDN) bearer service without the requirement to re-cable the installed fibre access. It has also been identified that there may be studies in other standardisation bodies that could have an impact on the requirements of the access network. As there has not been any input from these bodies at this time, their requirements have not been considered. [conversion of TM-TR 002 to ETR for referential purposes]
