According to NTT, this service is designed to reduce data transmission latency which is an issue when applying optical access systems, which are widely used for accessing the internet, to a mobile system. It is achieved by making optical line terminals and base station aggregation units in telecom office operate in coordination with the signal control. Applying optical access systems with the technology to a mobile system, it becomes possible to efficiently use optical fibers between a telecom office and base stations, NTT also said. This reduces both the number of optical fibers required and the ports of the base station aggregation unit. Detailed discussions on this services have been initiated at ITU-T.
