GPON optical wifi terminal HG8120 FTTH telecom OLT ONT device

The HG8120 GPON terminal (hereafter referred to as the HG8120) is an indoor optical network terminal (ONT) designed for home users and small office and home office (SOHO) users. Its upper shell adopts the natural heat dissipation material, and its optical port adopts the dust-proof design with a rubber plug. The HG8120 is eye-pleasing and energy-efficient. It can be deployed on a workbench or mounted on a wall, meeting users' deployment requirements in different scenarios.
By using the Gigabit-capable Passive Optical Network (GPON) technology, the HG8120 provides a high-speed data channel through a single optical fiber with an upstream rate of 1.244 Gbit/s and a downstream rate of 2.488 Gbit/s. In this way, you can enjoy the high-speed data service, quality voice service, superior video service.
As an ONT, the HG8120 provides the more convenient and efficient remote management function. It supports the ONT Management and Control Interface (OMCI) protocols and manages all home terminals in a unified manner, implementing remote fault diagnosis, service provisioning, and performance statistics.
