- Product Description - 

     8PON port cassette GPON-OLT exchange device with 8 downlink GPON ports, 8 uplink GE optical ports+8 uplink GE ports, with an extended slot for access to 210,000 megabytes SFP+ports.Height is only 1U, easy installation and maintenance, save space.With industry-advanced technology, strong capabilities and QoS guarantee in the Ethernet business, support for SLA and DBA.The optical ratio of 1:128 supports the hybrid network of different types of ONU, minimizing the investment of operators.

 - Product Features - 

1、 Provide high-density PON port, the whole machine can support 1024 ONU terminals, larger than the ordinary box OLT capacity.Each PON port supports a 1:1 separation ratio of 128 (maximum access to 128 ONU) and a hot-plug PON optical module design with a transmission distance of 20Km;

2、 Support PON fiber redundancy protection, automatic link protection switch in case of fiber failure;

3、 Comprehensive PON business capabilities, support dynamic bandwidth distribution DBA algorithm, dynamic Bandwidth Distribution Mechanism (DBA) enables all users to share 2.5Gbps bandwidth more reasonably and achieve reliable quality of service;

4、 Support rich Ethernet functions, with effective isolation guarantee mechanism, VLAN isolation, protection port, MAC address binding, IP address binding, port speed limit, queue technology, flow control technology, etc., for the technical guarantee of multi-business integration;

5、 Perfect security protection mechanism, adopts hardware-based package by packet forwarding, can effectively detect and filter feature messages, support A R P attack based on MAC address, automatic protection and automatic user blocking function, and prevent the attack of protocol messages.Support various anti-DDoS, CPU overload protection and VRRP and other equipment protection functions, to prevent illegal or abnormal traffic into entering the network, to resist a variety of virus attacks, to ensure the safety of equipment management;

6、 Rich business functions, fully support the second-floor business functions.Realize flexible QinQ and QoS and other advanced functions, ACL supports L2~L7 in-depth head 80-byte message filtering of IP messages, to provide high-quality QoS service quality guarantee for multi-business operation;

7、 Highly centralized operation management and maintenance, business-oriented, providing a unified network transmission and interconnection protocol, address management, domain name management, security management, user access management, etc.Rich OAM functions, including configuration, alarm, performance monitoring, fault isolation, and security management.
