Abstract

Recently, the development of passive optical networks (PON) for FTTH (Fiber-To-The-Home) have been actively conducted. In PON, a burst-mode transceiver is one of key modules. In this paper, we have made the protype module of a 155.52 Mpbs optical burst-mode transceiver with commercially available chips and then have measured the performance. Also, a new method of burst-mode clock recovery have been proposed. The burst-mode clock recovery implemented by using CPLD(Complex Programmable Logic Device) has coupled with the above burst-mode transceiver and has been tasted.

최근 FTTH (Fiber-To-The-Home) 구현을 위한 수동형 광 가입자망 (PON, Passive Optical Network)에 대한 연구가 매우 활발하게 진행되고 있다. PON 구성에 있어, 버스트-모드 광송수신기는 핵심이 되는 모듈이다. 본 논문에서는 상용화된 칩을 이용하여 155.52Mps급 버스트 모드 광송수신기 모듈 시제품을 제작하고 성능을 측정한다. 또한, 버스트-모드 광 클록 재생의 새로운 방법을 제안하고, CPLD(Complex Programmable Logic Device)를 이용하여 구현 한 다음, 제작된 모듈 시제품에 연동하여 성능을 비교하였다.
