Abstract

Recently, base stations composed of digital unit (DU) and radio unit (RU) have been widely used in 4G mobile networks. To connect DU and RU, CPRI (common public radio interface) is usually used as the interface standard. This CPRI link is considered as one of the application markets for WDM-PON. In this paper, we analyzed the required specification of WDM-PON for the CPRI link of the 4G LTE-Advanced base station composed of DU and RU. This analysis is important to set a target goal of the development of WDM-PON system for 4G mobile networks.

4G 이동통신 기지국에 있어서 최근에 DU (Digital Unit) 와 RU (Radio Unit) 로 분리되는 형상의 기지국이 많이 등장하고 있다. 본 논문에서는 차세대 4G LTE 및 LTE-Advanced 이동통신망에서 DU 와 RU 사이를 연결하는 CPRI (common public radio interface) 링크에 요구되는 통신망의 규격을 살펴보고 이를 WDM-PON 으로 구현하기 위한 요구규격을 분석하여 본 응용 시장에 뛰어들고자 하는 WDM-PON 시스템의 개발목표를 설정하고자 한다.
