Application Scenarios

1. Urban FTTH Network Upgrade in Mexico

A Mexican telecom operator deployed ZTE SFUL Control Boards in ZXA10 C600 OLTs for urban FTTH expansion. As the core switching and control unit, the SFUL supported 4 OLT slices and non-blocking data switching, enabling seamless connectivity for 50,000+ residential users. Its hot-swappable design allowed maintenance without service downtime, while load sharing mode ensured stable 4K streaming and broadband access. Paired with dedicated uplink boards, the SFUL optimized network resource allocation, meeting the operator’s high-density user coverage needs.

2. Enterprise Campus Network in Spain

A Spanish university adopted ZTE SFUL Control Boards with ZXA10 C650 OLTs to upgrade its campus network. The SFUL’s system control and management functions unified the network of classrooms, labs, and administrative buildings, supporting 10,000+ concurrent devices. Its rich interfaces (MGMT, Console, DIAG) simplified remote monitoring and debugging, and load balancing capability prevented congestion during peak usage. The board’s compatibility with ZTE’s PON cards ensured future scalability, aligning with the university’s long-term digital transformation plans.
