3 1. PON 소개 PON 일반소개 PON의구조는크게센터에위치하는 OLT장비와원격지에설치되는 ONU 장비로구성된다. OLT와 ONU 중간에광을분기하는스플리터가들어가며스플리터의분기에따라서 1:2, 1:4, 1:8, 1:16, 1:32의구조를갖는다. Splitter OLT 1:4 구조 ONU GE-PON FBW5000 시스템은 SOHO, CCTV 와 SMB 을포함하는거주자지역에 1G 의 Ethernet Data 와부가적인비디오서비스를제공가능하게하는플랫폼이다. 이 FTTH 액세스시스템은하나의광케이블구성에기반을두고하향 1490nm, 상향 1310nm, 그리고 1550nm 는 CATV 의방송용으로사용된다. 3
