EXECUTIVE SUMMARY

The ZXA10 C600 represents a paradigm shift in optical access platform engineering, embodying ZTE's TITAN architecture philosophy to deliver carrier-grade performance for next-generation FTTx networks. As a large-capacity optical line terminal (OLT) platform, the C600 addresses the escalating bandwidth demands of 4K/8K video, virtual reality, fixed-mobile convergence, and enterprise-grade connectivity scenarios . The platform's fully-distributed, programmable router architecture establishes a foundation for seamless evolution from GPON through XGS-PON and toward future 50G PON deployments, protecting operator investments across multiple technology generations .

HARDWARE ARCHITECTURE & SILICON

The ZXA10 C600 chassis is engineered around a high-end router architecture that fundamentally separates control plane and forwarding plane functions, enabling non-blocking traffic forwarding at line rate . At the silicon core, ZTE's in-house developed 16nm network processor (NP) integrates NP and fabric functions into a single chip, delivering industry-leading integration density . The 5-in-1 PON chipset achieves 16-port-per-chip density while consuming 31.8% less power than CoC v8 reference designs for Combo PON configurations . The backplane provides 14 Tbit/s switching capacity, while the main control switching cards deliver 3.68 Tbit/s per card and 7.36 Tbit/s system-level capacity .

KEY FEATURES & ROUTING LOGIC

- Fully-Distributed Switching Fabric: Control and forwarding planes operate independently with redundant control cards, enabling In-Service Software Upgrade (ISSU) and Non-Stop Routing (NSR) with zero service interruption .

- Three-Generation PON Coexistence: Single platform supports GPON, XG-PON, XGS-PON, 10G-EPON, and Combo PON technologies, with Any-PON capability permitting flexible technology switching without hardware replacement .

- Industry-Leading Port Density: Supports up to 272 GPON/XG-PON/XGS-PON/Combo PON ports in the 21-inch chassis configuration, or 240 ports in the 19-inch configuration .

- Non-Blocking Forwarding: 200G per service slot bandwidth eliminates oversubscription, ensuring deterministic performance for latency-sensitive applications including 5G uRLLC backhaul .

- SDN/NFV Readiness: Native NetConf/YANG support enables integration with third-party SDN controllers and orchestration systems, with built-in blade capability for NFVI deployment .

- Network Slicing: Hardware-level resource partitioning allows dedicated card, port, or ONU assignment to discrete network slices with guaranteed isolation .

COMPLIANCE & STANDARDS

The ZXA10 C600 conforms to international telecommunications standards including ITU-T G.984.x (GPON), G.987.x (XG-PON), G.9807.1 (XGS-PON), and G.988 (OMCI). Ethernet services comply with IEEE 802.1Q, 802.1ad, 802.1ag, and 802.3 standards. The platform supports MEF-compliant Carrier Ethernet services and holds CE and RoHS certifications for European market deployment . Synchronization capabilities meet ITU-T G.8262, G.8264, and G.781 requirements for frequency and time distribution .
