FTTH (Fiber To The Home) Of The Applied Research

FTTH (fiber to the home) is a kind of optical access application model what can be used at home or in enterprise via ONU(optical network unit),which is the closest application model can be used by the end user. In order to meet with user's requirement of broadband,fast,feasibility and stability application on video, digital TV and IPTV multiple media. The local marketing is getting more serious demands to low-coast application which apply to current flush business challenge. Thus lead to brand new topic in next 4 to 5 years with highly FTTH conception in China. In recent years,the FTTH relevance technology develops rapidiy , the hot spot technology , BPON(APON), nonstandard all kinds of from 155 Mb/s and 622 Mb/s already becoming the telecornrnunication field foretell standard ITU-T GPON that EPON develops to standard EPON of IEEE and 2.5Gb/s supporting 1.25 Gb/s circuits rate.First of all, this paper has summarized FTTH system structure, hat is, point-to -point (P2P) and point-to-multipoint (P2MP) access technology, in several of PON access technology for detail, especially on the EPON, GPON technology compared. Secondly, this paper analysis and on the principle of EPON, the system architecture and key technologies. Third, the use of EPON discusses the significance of network -ing and principles, on this basis was introduced for the customers to chieve different FTTH solutions FTTH in the field of communication and Internet pplications are discussed; Finally, the budget building the hit the target set of net pattern,bandwidth in the business network plan communicating by letter being in motion and doing business , ODN concentrating on having set forth EPON FTTH plan the main body of a book waiting for the key teehnology. Take EPON project as example at the same time,different construction pattern in realizing a scheme ,discussing a network to EPON in being in motion and doing business being in motion and doing business having brought forward EPON FTTH and verifying has carried out investigation and discussion.
