Each PON port supports a 1:128 light splitting ratio (maximum access to 128 ONUs). The hot plug PON Optical module is designed to support a transmission distance of up to 20Km;
2. Support PON fiber redundancy protection, automatic link protection switching in case of fiber failure;
3. Comprehensive PON service capability, supporting dynamic Bandwidth allocation DBA algorithm, and dynamic Bandwidth allocation mechanism (DBA) enables all users to share 2.5Gbps bandwidth more reasonably to achieve reliable quality of service;
4. Supporting rich Ethernet functions, with effective isolation and protection mechanisms, VLAN isolation, protection ports, MAC address binding, IP address binding, port speed limiting, queue technology, flow control technology, etc., providing technical support for the development of multi-service integration;
5. A comprehensive security protection mechanism adopts hardware based packet by packet forwarding, which can effectively detect and filter feature packets. It supports MAC address based ARP attack automatic protection and automatic user blocking functions to prevent protocol packet attacks. Support various device protection functions such as DDoS prevention, CPU overcurrent protection, and VRRP to prevent illegal or abnormal traffic from entering the network, resist various virus attacks, and ensure the security of device management;
6. Rich business functions, fully supporting second tier business functions. Implementing advanced functions such as flexible QinQ and QoS, ACL supports L2 to L7 deep IP packet filtering of 80 bytes in the header, providing high-quality QoS service quality assurance for multi business operation;
7. Highly centralized operation management and maintenance, business oriented, providing unified network transmission and interconnection protocols, address management, domain name management, security management, user access management, etc. Rich OAM functions, including configuration, alarms, performance monitoring, fault isolation, and security management.
