TnT-G3004-L3 – 4-Port GPON OLT for Compact & Scalable FTTH Networks
The OLT 4 port GPON TnT-G3004-L3 is a highly efficient and compact designed for cost-effective fiber-to-the-home (FTTH), fiber-to-the-building (FTTB), and fiber-to-the-premises (FTTP) deployments. Built for small to medium-sized ISPs, telecom providers, and enterprise networks, this OLT delivers exceptional performance, high port density, and enterprise-grade Layer 3 features in a compact 1U form factor.
Supporting up to 512 subscribers through a 1:128 split ratio, the TnT-G3004-L3 is ideal for fiber network operators seeking a balance of performance, flexibility, and affordability.
Key Features of TnT-G3004-L3 4-Port GPON OLT
1. High-Capacity GPON Access
Equipped with 4 GPON ports, the OLT supports a downstream data rate of 2.5 Gbps and an upstream rate of 1.25 Gbps per port. Each GPON port can connect up to 128 ONUs/ONTs, giving the device a total capacity to serve 512 end-users from a single chassis.
This makes it suitable for:
FTTH deployments in residential areas
Smart city infrastructure
Campus and hospitality networks
Broadband delivery in rural and semi-urban regions
2. Advanced Layer 3 Routing Capabilities
The TnT-G3004-L3 is equipped with rich Layer 3 functionality, allowing it to operate as both an access and core device in a fiber network. Supported protocols include:
Static Routing
RIP v1/v2
OSPF
Policy-Based Routing (PBR)
DHCP Server and DHCP Relay
With these capabilities, it handles complex routing tasks, inter-VLAN communication, and scalable user traffic management efficiently.
3. Versatile Uplink Interfaces
The OLT features flexible uplink interfaces for core network connectivity:
2 × 10GE SFP+ ports for high-speed fiber uplinks
2 × 1GE SFP ports for standard gigabit connections
These uplink ports support link aggregation and redundancy, ensuring seamless data flow and failover for mission-critical services.
4. Powerful Quality of Service (QoS)
To ensure smooth delivery of broadband, video, and VoIP services, the TnT-G3004-L3 includes powerful QoS mechanisms:
Traffic classification based on 802.1p/DSCP
Bandwidth control per port or user
Multi-level priority queues
Traffic shaping and rate-limiting
This prioritizes time-sensitive data like voice and video for a better user experience.
5. Comprehensive Security Features
Security is a top priority in GPON networks, and the TnT-G3004-L3 provides:
User access control via 802.1x and Radius authentication
MAC address filtering and binding
Loop detection and port isolation
Anti-ARP spoofing and IP source guard
DDOS prevention and broadcast storm suppression
These features safeguard the network from intrusions, loops, and bandwidth abuse.
6. Centralized and Simplified Management
For easier network administration and scalability, the device supports multiple management methods:
Web-based GUI
Command Line Interface (CLI)
SNMP v1/v2/v3
EMS/NMS (compatible with TR-069)
Telnet, SSH, and Syslog
With these options, administrators can remotely manage the network, monitor performance, configure policies, and update firmware with ease.
7. Energy-Efficient and Space-Saving Design
Designed with practicality in mind, the TnT-G3004-L3 is built in a compact 1U rack-mountable chassis, consuming minimal power and space while delivering maximum efficiency. It’s ideal for deployments in:
Small network rooms
Data centers
Shared telecom cabinets
Its robust design ensures 24/7 stability even in demanding environments.
