What is Huawei OLT Board?

A Huawei OLT (Optical Line Terminal) Board is a critical hardware component in fiber-to-the-premises (FTTP) networks, acting as the central equipment at the service provider's end, with popular series like the MA5800 supporting high-density PON technologies (GPON, 10G PON, 50G PON) for connecting numerous users, featuring high capacity, flexible deployment, and support for various service types, enabling gigabit broadband and advanced video. Key models include GPON interface boards like the H901GPHF for high user capacity and specialized control boards like SCUN for system management.

Key Features & Types
High Density: Boards like the GPHF offer 16 GPON ports, supporting many users (e.g., 2,048) from a single card.
PON Technology Support: Boards support different PON standards (EPON, GPON, XG-PON, XGS-PON, 50G PON) for evolving network needs.
Advanced Platforms: The MA5800 series OLTs use a distributed architecture, moving service processing to boards for greater flexibility and supporting 4K/8K/VR.
High Throughput: Supports massive backplane capacity (e.g., 1 Tbps/slot for MA5800) for demanding bandwidth.
Control Boards (e.g., SCUN): Manage system functions, service switching, and overall network management.
Reliability: Features like Type B homing, Forward Error Correction (FEC), and high-temperature alarms enhance network stability.

Function
OLT boards aggregate traffic from many ONTs (Optical Network Terminals) at user premises, acting as the gateway to the optical network, reducing the need for many separate network nodes.
