functional characteristics

        Meet ITU-T G.984/G.988 standards and meet relevant GPON standards in China's communications industry

        Supports OMCI remote management of ONTs/ONUs and is compatible with ITU-984.4 OMCI protocol

        1U high 4PON Pizza-Box compact design OLT products

        Provides 4 GPON ports, 8 uplink GE optical ports, 8 uplink GE electrical ports, and the 10G card expansion slot provides 2 10G             SFP+ uplink ports; a single PON port supports 128 ONT access, fully equipped with 512 terminals; Dual power supply redundant         power supply, supporting mixed plugging of 220VAC and-48VDC.

Improve Layer 2 switching functions

        OLT has strong Layer 2 line-speed switching capabilities and complete Layer 2 protocol support. It has switching, isolation and One By One working modes; supports rich Layer 2 functions such as port aggregation, VLANs, port speed limit, queue technology, flow control technology and ACL, providing a technical guarantee for the development of multi-service integration.

QoS guarantee

        GPON products have complete DBAs and excellent QoS service capabilities. DBA provides various QoS for the GPON system through four types of bandwidth and five types of T-CONT, which can meet different QoS requirements for different traffic flows such as delay, jitter, and packet loss rate.

Easy-to-use management system

Support CLI and SNMP management solutions, meet the OMCI specifications, and realize service management through the OMCI channel protocol, including ONT's functional parameter set, T-CONT service type and quantity, QoS parameters, request configuration information and performance statistics, automatically notify the system of running events, and realize OLT's management of ONT configuration, fault diagnosis, performance and security.

Product characteristics:

1. Provide high-density PON ports. The whole machine can support 1024 ONU terminals when fully equipped, which is larger than ordinary box OLT capacity. Each PON port supports an optical splitting ratio of 1:128 (maximum access to 128 ONUs). The hot plug PON optical module design supports a transmission distance of up to 20Km;

2. Support PON optical fiber redundancy protection and automatic link protection switching when an optical fiber fails;

3. Comprehensive PON service capabilities and support dynamic bandwidth allocation DBA algorithm. Dynamic bandwidth allocation mechanism (DBA) allows all users to share 2.5Gbps bandwidth more reasonably and achieve reliable quality of service;

4. Supports rich Ethernet functions, and has effective isolation guarantee mechanism, VLAN isolation, protected ports, MAC address binding, IP address binding, port speed limit, queue technology, flow control technology, etc., which plays a role in the development of multi-service integration. Technical guarantee;

5. A complete security protection mechanism adopts hardware-based packet-by-packet forwarding, which can effectively detect and filter characteristic messages, supports automatic protection against ARP attacks based on MAC addresses and automatic user blocking functions, and prevents attacks on protocol messages. Support various device protection functions such as anti-DDoS, CPU overcurrent protection, and VRRP to prevent illegal or abnormal traffic from entering the network, resist multiple virus attacks, and ensure the security of device management;

6. Rich business functions and fully support second-layer business functions. Realizing advanced functions such as flexible QinQ and QoS, ACL supports L2 to L7 in-depth packet filtering of 80 bytes at the header of IP messages, providing high-quality QoS quality of service guarantee for multi-service operations;

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, alarm, performance monitoring, fault isolation and security management.
