| As in recent years, the concept of three nets FTTx technology also arises at the historicmoment, as its main network technology, EPON system relying on its large bandwidth,economical, and many other characteristics are widely used at present.Of the so-called three nets are originally independent operation of traditionaltelecommunication network design, computer Internet and cable television network will bemutual penetration and mutual fusion. Accordingly, three kinds of different business, marketand industry will also be mutual infiltration and mutual confluence, three big business to splitthe boundaries between the three major market and industry gradually become blurred,gradually formed a unified network system, and the fully digital network infrastructure tosupport, including data, voice and video image, all the business communication.FTTx technology goal is to use optical fiber to replace the traditional copper wire, usingoptical fiber as transmission medium directly to the user terminal equipment, to realize in thetrue sense of the all all-optical network. FTTx network technology is mainly Ethernet passiveoptical network. Ethernet Passive Optical Network (Ethernet Passive Optical Network, EPON)is a new kind of Optical fiber access Network technology, the use of point to multipoint userNetwork topology structure, use of Passive Optical fiber for data, voice and video of thewhole business access purpose. It had been used in the physical source optical network (PON)technology, the link layer using the Ethernet protocol. Due to its Ethernet and PONtechnology perfect combination, thus became the very suitable for business of broadband IPtechnology.In this paper, first of all, the implement principle of EPON and EoC, key technology andtechnical advantages are briefly introduced. First analysis of the present condition of the threenets fusion technology, summarizes the aspects, such as business model, and compare threenets fusion scheme, and the implementation of the key points in the process of EPONequipment type, business type, protocol of ONU requirement elements such as, finally, basedon the triple play of EPON and EoC is summarized and prospected. |
