GPON（Gigabit Passive Optical Networks）代表基于ITU-TG.984x的PON接入宽带最新标准，可提供 高带宽、高效率的服务、广范围的信号覆盖和丰富的接入端口。被运营商认为是实现接入网不同需求的理想技术。

2023年12月6日 · GPON is an alternative to Ethernet switching in campus networking. GPON replaces the traditional three-tier Ethernet design with a two-tier optic network which eliminates access and distribution Ethernet switches with passive optical devices. Cisco introduces GPON with the Catalyst GPON platform.

2022年7月27日 · 在千兆以太网无源光网络（GEPON）系统中，服务提供商的中心局有一个光线路终端（OLT），终端用户附近有多个光网络单元（ONU）或光网络终端（ONT），作为分光器（SPL）。此外，OLT与ONU/ONT之间的传输也使用了ODN（Optical Distribution Network）。 光 …

光纖網路終端 (ONT)/光纖網路單元 (ONU)：可將使用者裝置（桌上型電腦、電話等）連線至 GPON 網路，並提供從光纖到電子訊號的轉換。 此外，ONT 也透過 ONT 金鑰提供 AES 加密。 分線器：用於將光纖訊號彙總或多工傳輸至單一上游光纖纜線。 比例通常為 1:32。 光纖線路終端機 (OLT)：可將所有光纖訊號從 ONT 彙總至單一多工傳輸光束的裝置，接著再將該光束轉換成電子訊號，並格式化成乙太網路封包類型的標準，以進行第 2 層或第 3 層轉送。 波長分波多工 …

The GPON ONU (ONT) and GPON OLT are two primary components that make a GPON network function. The OLT acts as the central point of management and data distribution, while the ONT handles the end-user side, converting the optical signals into usable data for local devices.

What is GPON? GPON stands for Gigabit Ethernet passive optical network. GPON also gives access to Internet, voice and video service. The difference is that GPON uses ATM for voice, Ethernet for data, and proprietary encapsulation for voice.

2023年9月19日 · In a Gigabit Passive Optical Network (GPON), the ONT plays a significant role in transmitting data from the Optical Line Terminal (OLT) to the end-user device. The ONT receives downstream signals from the OLT that are transmitted over the fiber optic cable.

The Huawei OptiXstar EG8145X6-10 is an intelligent GPON and Wi-Fi routing-type ONT. It uses the GPON Wi-Fi technology to implement ultra-broadband access, high performance and wide coverage for users.

2018年2月26日 · User-side Optical Network Terminals (ONTs) for Fiber-To-The-House (FTTH) solutions provide high-bandwidth access for Small Office/Home Office (SOHO) environments using GPON technologies.

OLTs normally support up to 72 ports. An ONU connects to end users and will send their signals back to the OLT. A GPON network can reach up to 20 km and provide service up to 64 end users. GPON utilizes both upstream and downstream data by means of Optical Wavelength Division Multiplexing (WDM).
