DT-GOLT-1004S provides 4GPON ports, 8 uplink GE optical ports + 4 uplink GE electric ports, 10 Gigabit card expansion slot provides 2*10Gigabit SFP+ uplink port. Each PON port supports 128 ONT, total 512 ONT for one chassis. Support dual power supply redundancy, 220VAC and -48VDC mixed.
SFU, HGU series ONT products, Meet the needs of the different scenarios of networking
The complete layer 2 switching function
OLT is with powerful layer 2 switching capacity and complete layer 2 protocol. Supporting with the exchange, isolation and One By One working mode. Supporting port aggregation, VLAN, port speed, queue technology, flow control technology and ACL rich two layer function. Offering the technical support for the development of the multi-service fusion.
The QOS security
GPON products is with complete DBA function and excellent ability of QoS service. DBA provides a variety of QoS for the GPON system by means of four types of bandwidth and five types of T-CONT. It can meet different business flow of time delay, jitter and packet loss rate of different QoS requirements.
Easy-to-use management system
Support CLI and SNMP management. complying with OMCI standard. Realizing the business management through OMCI channel protocol, including the ONT function parameters, type and number of T-CONT business, QoS parameter, configuration request information and performance statistics, automatic notification running event system, the realization of OLT on ONT configuration, fault diagnosis, performance and security management.
