Abstract

For the key technologies of maneuvering optical access networking in emergency communication, based on the existing communication network, this paper studies the ONU hardware, OLT power supply and reset module, OLT terminal integrated bandwidth allocation algorithm, OLT optical burst emission / reception module, HOST subsystem and OLT subsystems, structure of maneuvering fiber access networking, overall performance design of system and the organization method of mobile optical access system. Broadband access technology of maneuvering fiber access networking in emergency communication is realized finally. At present, the NIMS of the United States the Disaster Prevention Center of Japan and the e-RISK of the European Union in foreign countries are with clear division of responsibilities, complete emergency response system and advanced communication means with being developed and perfected over the years. In particular, the EU e-RISK system, which makes extensive use of satellite-based communication technology, provides support services for the efficient and timely handling of public emergencies and natural disasters across national. After a major natural incident, it is effective to avoid situations where rescue personnel are unable to communicate with exports from the command centre in timely as the disruption of communications systems and the severe congestion of channels. After the extreme natural disaster, it is very important to ensure communication between the disaster area and the outside world, to know the emergency situation of the disaster area and to provide the necessary information for the rescue work. Based on the existing communications networks, the technical standards for the equipment of mobile geographic communications networks and for fiber communications of fixed communication stations(G. 703), the technical standards for computer networks(IEEE 802.3) and the technical standards for passive optical access to the ether, as well as the problems of traditional means of access for the establishment of critical technologies for emergency communications network. In this paper, the structure construction, key technology realization, system performance realization and system organization application method of mobile light access network system(Y-EPON) in mobile and fixed emergency communication are studied, and the comprehensive information access of broadband is realized.
