The Huawei CGHD (H902CGHD) is an 8-port Combo PON OLT board for the SmartAX MA5800 platform, combining GPON & XG-PON for high-density FTTx, offering features like high capacity (16368 service flows), advanced protection (Type C), energy efficiency (low power), hot-swappable design, and future-proofing for next-gen PON, enabling high-speed, reliable broadband delivery.
Product Features
Combo PON Technology: Supports both traditional GPON (2.5G/1.25G) and faster XG-PON (10G/2.5G) on the same board, allowing flexible upgrades.
High Density: 8 ports per board, crucial for extensive service coverage in FTTx networks.
High Capacity: Handles up to 16368 service flows and 131072 MAC addresses, ensuring scalability.
Advanced Protection: Offers Type C (dual-homing) protection for PON channels and support for dual upstream channels with smart link/monitor link.
Reliability: Includes fault pre-warning, high-temperature detection, and protection circuits for power input.
Energy Efficiency: Low power consumption (around 51W max for 8 ports) and an energy-saving bus for idle cards.
A leading telecom operator in Italy deployed CGHD service boards with MA5800-X15 OLTs to migrate its urban GPON network to 10G, covering 150,000 households (90,000 existing GPON users + 60,000 new 10G subscribers) in Milan. Each CGHD’s 4 GPON ports seamlessly retained legacy users’ services, while 4 XGS-PON ports delivered 10G symmetric broadband for 8K IPTV, low-latency cloud gaming, and enterprise high-speed access. Paired with Class N1 modules, it achieved 25km transmission to cover suburban areas, and 75 CGHD boards (600 total ports) completed the migration with zero service downtime. The high-density hybrid design cut OLT slot usage by 50% compared to separate boards, reducing annual operational costs by 30%.
