Application Scenarios
1. 5G & FTTH Convergence in Italy
Italian FWA operator EOLO deployed ZTE Enhanced SFUH Control Boards in ZXA10 C600 OLTs to support its 5G SA millimeter-wave network rollout. The SFUH’s integrated 4×10GE uplink ports simplified 5G small cell backhaul integration, while 4 OLT slices enabled isolated management of residential FTTH and enterprise VPN services. Hot-swappable design and load balancing ensured 99.99% uptime for 1Gbps ultra-broadband services, aligning with Italy’s digital transformation goals to bridge urban-rural gaps.
2. Enterprise Campus Upgrade in Germany
German operator E-Plus adopted ZTE Enhanced SFUH Control Boards for a large university campus network in Berlin. As a strategic partner, ZTE’s SFUH boards provided non-blocking data switching and unified control for 20,000+ concurrent devices (labs, classrooms, dormitories). Rich interfaces (MGMT, DIAG) facilitated remote monitoring, and dual-board redundancy guaranteed zero downtime for critical research data transmission. The board’s scalability also supported future 10G PON upgrades seamlessly.
