Designed for high-density, high-availability service delivery, the ZXA10 C300 provides a robust foundation for HSI, VoIP, TDM, IPTV, and mobile backhaul services. This document provides a detailed technical overview and hardware datasheet for the ZXA10 C300, highlighting its architectural design, key hardware features, and comprehensive technical specifications.
ARCHITECTURE & CHASSIS DESIGN
The ZXA10 C300 is a highly modular, chassis-based platform built on a fully redundant 400Gbps backplane, delivering up to 20Gbps of throughput per service slot . It is available in two industry-standard chassis configurations to suit diverse central office environments:
– 19-Inch (IEC) Chassis: Occupies 21 slots and is designed for standard 19-inch equipment racks .
– 21-Inch (ETSI) Chassis: Occupies 23 slots and is designed for wider 21-inch ETSI racks, offering increased capacity .
Both chassis share a common architectural philosophy, with clearly defined functional zones for power, main control, service, uplink, and public interface cards. The system incorporates a sophisticated cooling mechanism with a 1U fan tray that uses forced-air exhaust. Fan speed is dynamically adjusted based on real-time temperature monitoring, optimizing acoustic performance and extending the operational lifespan of the equipment .
HARDWARE FEATURES
1. High-Performance Switching Fabric: At the heart of the ZXA10 C300 is a high-reliability, non-blocking switching architecture. The system can be configured with two main control cards (SCXL/SCXM) operating in a 1:1 redundancy mode for maximum system availability .
2. Universal Service Slots: The platform features universal line card slots, providing exceptional deployment flexibility. A single slot can accommodate a variety of service cards, including PON (GPON/EPON), P2P, and TDM interface cards .
3. Comprehensive Interface Portfolio: The ZXA10 C300 offers a complete range of interfaces for any access network scenario:
– Subscriber-Side Interfaces: Supports high-density GPON and EPON cards with up to 8 ports per card, as well as 16-port P2P cards and 4-port 10G EPON cards .
– Network-Side Interfaces (Uplinks): Provides a variety of uplink options, including 4x10GE, 4/8/16xGE, and TDM uplinks such as STM-4/OC-12 and STM-1/OC-3 .
4. Advanced Redundancy & Reliability: The chassis supports power supply redundancy (1+1) and optical link protection (Type B and Type C), ensuring carrier-grade reliability for critical services .
COMPLIANCE & STANDARDS
The ZXA10 C300 is engineered to meet the most rigorous industry standards and certifications, ensuring interoperability and operational excellence in global telecom networks.
– PON Standards: Fully compliant with IEEE 802.3ah (EPON), ITU-T G.984.x (GPON), and IEEE 802.3av (10G EPON) .
– Layer 2/Layer 3 Features: Supports a full suite of Layer 2 and Layer 3 protocols, including 802.1Q VLAN, 802.1ad (QinQ), STP/RSTP/MSTP, link aggregation (802.3ad), and static/dynamic routing .
– Quality of Service: Implements comprehensive QoS mechanisms with 8 queues per port, advanced scheduling algorithms (SP, WRR, SP+WRR), and DiffServ to guarantee service differentiation for voice, video, and data .
– Environmental: The system is designed to operate reliably in a wide range of environmental conditions, adhering to strict temperature and humidity specifications for central office equipment.
