Based On Research And Application Of Epon For Ftth Network Planning And Construction

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 rapidly , the hot spot technology , BPON (APON) , nonstandard all kinds of from 155 Mb/s and 622 Mb/s already becoming the telecommunication field foretell standard ITU-T GPON that EPON develops to standard EPON of IEEE and 2.5 Gb/s supporting 1.25 Gb/s circuits rate.First of all, this paper has summarized FTTH system structure , the technology has assumed comparatively detailed discussion and comparison to EPON , GPON. Secondly, analyse and resolve having set forth the EPON principle and the key technology, and having introduced that area , office building , housing estate corridor and important customer use EPON to realize FTTH's specifically for the villa a scheme.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 technology. Take Fuzhou telecommunication 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.
