The switching and control cards for ZXA10 C600/C650 OLTs—classified into two series: Enhanced SFUL/SFUP/SFUH/SFUQ and SPUF/SPUFS—are hot-swappable and support load sharing, load balancing, 4 OLT slices, full system control and management functions, as well as non-blocking data switching between all line cards; regarding interface configurations, Enhanced SFUL/SFUP/SFUH/SFUQ models are equipped with one out-band management (MGMT) interface, one maintenance serial (Console) interface, one USB interface, one mirroring diagnosis network (DIAG) interface, and one line card debugging serial (ODB) interface, while SPUF/SPUFS models feature one out-of-band management (MGMT) interface, one maintenance serial (Console) interface, one environmental detection serial (Monitor) interface (supporting 3 digital input and 1 digital output interfaces), and one line card debugging serial (ODB) interface; additionally, Enhanced SFUH/SFUQ support four 10GE/GE uplink interfaces, SPUF/SPUFS provide four 10GE/GE Ethernet optical interfaces, and SPUFS exclusively supports the IEEE 1588 function.
1. National Broadband Convergence in South Africa
A leading South African operator deployed ZTE Enhanced SFUQ Control Boards in ZXA10 C600 OLTs to upgrade its nationwide fiber network. The SFUQ’s integrated 4×10GE uplinks simplified backbone connectivity, while 4 OLT slices enabled isolated management of residential FTTH and rural education broadband services. Hot-swappable design and load balancing ensured 99.99% uptime, supporting the operator’s goal of bridging urban-rural digital gaps under South Africa’s national broadband plan.
2. Enterprise & Public Safety Network in Germany
ZTE Enhanced SFUQ boards were adopted by a German municipal government for its smart city project, paired with ZXA10 C650 OLTs. The boards provided unified control for enterprise VPNs, traffic monitoring systems, and public safety communications. Rich debugging interfaces (DIAG, ODB) facilitated 24/7 remote maintenance, critical for emergency response services. Dual-board redundancy guaranteed zero downtime, aligning with Germany’s strict network reliability standards for public infrastructure.
