5G 프론트홀 전송을 위한 세미액티브 WDM 시스템

제품개요

5G 네트워크를 구축한 후 기지국 밀도는 4G 네트워크의 2~4배가 되며, 5G 프런트홀 구축에서 광섬유 제약이 직면하는 주요 문제가 될 것입니다. 기지국의 신속한 구축을 충족 하고 4G 및 5G 네트워크 구축에서 광섬유 리소스를 효과적으로 절약하기 위해 통신업체는 WDM 멀티플렉서와 컬러 조명 모듈을 결합한 솔루션을 채택하여 저비용의 빠른 커버리지를 달성했습니다. 그러나 실제 적용에는 단점과 문제점도 있습니다 .

능동 WDM 또는 OTN 기술을 사용하는 솔루션은 광 경로의 네트워크 관리 및 기본/백업 경로 선택의 어려움을 해결할 수 있지만 높은 비용과 원격 전원 공급의 어려움과 같은 과제도 직면합니다.

능동형 및 수동형 WDM에 대한 이전의 기술 축적과 연구, 수요를 운반하는 프런트홀 장비에 대한 고객 불만 사항과 결합된 지속적인 심층 이해를 바탕으로 광저우 루이 동은 기지국 프런트홀용 솔루션으로 반능동형 WDM을 도입했습니다.

반능동 WDM 솔루션은 로컬 끝의 능동 장비와 원격 끝의 수동 장비를 사용하여 배포 및 유지 관리를 용이하게 합니다. 로컬 장비를 통해 네트워크 관리, 회선 보호 및 빠른 OTDR 오류 위치 확인 기능을 지원합니다. 유지 관리 방법은 편리하고 유연하며 높은 신뢰성 요구 사항을 충족합니다. 이 솔루션은 광섬유 리소스에 대한 부담을 크게 완화하는 동시에 비용, 관리 및 보호 이점의 균형을 유지함으로써 사업자가 5G 프런트홀 네트워크를 저비용, 고대역폭 및 신속하게 배포할 수 있도록 지원합니다.

이 솔루션은 확장된 기지국의 광섬유 리소스가 부족한 시나리오, 단순한 듀얼 스타 또는 버스 유형 네트워크 구성(고속도로, 고속철도, 터널, 교량 등의 시나리오 포함)에 적합합니다. AAU 및 DU 장비에 컬러 조명 모듈이 장착되어 있으며 전송에 WDM 기술을 사용하여 광섬유 자원을 절약하고 OADM 업/다운 웨이브 기능을 지원합니다. 또한 프런트홀 서비스 보호를 위해 이중 경로 광섬유 케이블을 활용하는 동시에 레거시 4G 프런트홀 광섬유를 지원하여 4G/5G용 통합 프런트홀을 달성할 수 있습니다.
