FAQS: 

Q1: What is the maximum number of ONU connections supported by this device? How to achieve mass management?
A: 单PON口支持64个ONU接入，设备满配时通过多PON口级联，可实现256个ONU的统一管理，配合自动发现注册机制，简化大规模部署。

Q2: What are the main advantages of dual power supply design?
A: 双电源热备份方案可确保单点电源故障时无缝切换，配合冗余模块设计，使设备可靠性达到99.999%电信级标准，适用于核心网络节点。

Q3: How can DBA technology optimize network performance?
A: 动态带宽分配技术实时监测业务流量，按需分配带宽资源。例如视频业务可获得更高带宽保障，而普通数据业务则动态共享剩余带宽，提升整体链路利用率。

Q4: What scenarios does the VLAN Stacking (QinQ) function apply to?
A: 主要用于运营商级网络分层管理，通过双层VLAN标签实现用户业务与运营商网络的隔离。典型应用包括企业专线接入、IPTV业务隔离等场景。

Q5: What early warning mechanisms are included in the optical link diagnosis system?
A: 系统实时监测光功率、信噪比、误码率等关键参数，当检测到光衰超过阈值或光纤中断时，立即触发告警并通过SNMP Trap上报管理系统，支持预定义阈值自定义设置。
