Standalone GPON OLT
The DM461x line has models of OLTs GPON for the most varied FTTx applications. The Datacom OLTs Portfolio includes models with 4, 8 and 16 PON ports, in addition to a variety of 1GE and 10GE interface options. All models support 1:128 split ratio, totaling capacities ranging from 512 to 2048 clients per OLT.
The OLT DM4611 4GPON + 2GT + 2XS is the ideal model for applications where there is low population density, that is, condominiums and small neighborhoods.
With its optimized number of ports and desktop installation option, this equipment brings versatility to service provider applications.
All Datacom OLTs are compliant with the ITU-T G.984 and ITU-T.988 standard. Each GPON link supports 2.488 Gbit/s downstream and 1.244 Gbit/s upstream rates and offers dynamic bandwidth allocation (DBA).
The configuration of the ONUs of the network is carried out remotely by the OLTs through the OMCI protocol according to the ITU-T standards. Even FXS ports to provide VoIP services to customers can be configured this way.
Being able to use 4094 VLANs defined in the IEEE 802.1Q standard simultaneously, in addition to offering Q-in-Q and VLAN translate functionalities, allowing double TAG, addition (Q-in-Q), removal or replacement of VLANs, the DM461x line serves one wide range of applications and needs for GPON network concentration and interconnection with Metro Ethernet networks.
The prioritization of traffic and services at different levels is achieved with QoS (Quality of Service) functionalities, such as traffic classification, SP and WFQ scaling, DSCP to P-bit (PCP) mapping, among others.
The Spanning Tree (STP) and Rapid Spanning Tree (RSTP) protocols and ring operation via the EAPS or ERPS protocol are supported, ensuring the protection of Ethernet uplinks. In addition, the Link Aggregation feature (LAG / LACP) allows for quick uplink extensions.
Through the IGMPv2/v3 protocols, multicast traffic is distributed to all customers through a single instance of each flow, enabling the provision of video and IPTV services.
The entire line of Datacom OLTs is based on the DmOS operating system, allowing management via a command-line interface (CLI) accessible through SSHv2, Telnet and RS-232 Console. SNMP v1, v2c and v3 agents and an XML interface based on the NETCONF standard are also available. DmOS also allows commit and rollback operations, use of user authentication via RADIUS and TACACS, local and remote Syslog, facilitating equipment configuration, management and troubleshooting.
