Key Features of TnT-E2004-L3

---

1. 4 GEPON Ports for Efficient Subscriber Connectivity

The TnT-E2004-L3 features 4 GEPON ports, each supporting symmetrical data transmission rates of 1.25 Gbps upstream and downstream. With support for up to 256 ONUs/ONTs (using a 1:64 splitter ratio per port), this OLT is built to serve:

• Residential broadband users

• Small and medium-sized enterprises

• Educational institutions

• Government and municipal projects

It allows service providers to scale efficiently without compromising performance.

---

2. Layer 3 Routing for Intelligent Traffic Handling

3. Multiple High-Speed Uplink Ports

The device includes both Gigabit and 10-Gigabit SFP/SFP+ uplink interfaces, ensuring smooth data backhaul to the core network. These uplinks provide:

• High bandwidth for upstream traffic

• Redundancy and load balancing options

• Support for fiber uplinks to reduce latency

It allows seamless integration into existing infrastructures and ensures uninterrupted connectivity.

---

4. Advanced QoS and Bandwidth Management

The TnT-E2004-L3 supports a comprehensive set of Quality of Service (QoS) policies, such as:

• Bandwidth control per user or VLAN

• Traffic prioritization for voice, video, and data

• Multiple queues per port

• Congestion management and traffic policing

These tools allow ISPs and admins to deliver guaranteed service levels and prioritize mission-critical applications.

---

5. Carrier-Grade Security

Security is paramount in modern broadband networks, and the TnT-E2004-L3 delivers with features like:

• MAC address binding

• Access Control Lists (ACLs)

• User authentication

• Port isolation

• ARP and DHCP snooping

These measures protect both the network and end-users from unauthorized access, attacks, or service abuse.

---

6. Powerful Centralized Management

The OLT offers flexible and centralized network management via:

• Web-based GUI

• CLI (Console and Telnet)

• SNMP v1/v2/v3

• TR-069

• EMS/NMS platforms

With support for remote monitoring, configuration, and firmware updates, service providers can reduce operational costs and improve service delivery times.

---

7. Compact, Durable & Energy-Efficient Design

Designed for 1U rack-mount installation, the TnT-E2004-L3 is space-saving and energy-efficient, consuming low power and generating minimal heat. It is ideal for:

• Telecom cabinets

• Central offices

• Compact server rooms

It provides reliable 24/7 operation, even in demanding environments.

---

Ideal Applications

• ISPs & Cable Operators: Scalable broadband services for homes and offices

• Smart Cities: Backbone for surveillance, IoT, and public Wi-Fi

• Corporate Networks: Secure, high-speed communication across branches

• Educational Institutions: Seamless access to online learning and campus-wide internet
