The ZTE ZXA10 C600, C650, and C680 are high performance GPON Optical Line Terminals (OLTs) designed for next generation broadband access networks. These devices are equipped with a 16 port GPON interface board that supports a variety of advanced features to ensure high speed data transmission and efficient network management. The C++ module integrated into these systems is a critical component that enables the customization and enhancement of the OLT's functionality.

Key Specification Parameters:

1. GPON Interface: Each model (C600, C650, C680) is equipped with a 16 port GPON interface board, which allows for the connection of multiple Optical Network Units (ONUs) to the OLT. This board supports the GPON standard, ensuring compatibility with a wide range of ONUs.

2. Data Rate: The GPON interface supports downstream data rates of up to 2.5 Gbps and upstream data rates of up to 1.25 Gbps, providing high speed connectivity for users.

3. C++ Module: The C++ module is a software component that allows for the development of custom applications and services on the OLT. It enables network administrators to tailor the OLT's functionality to meet specific network requirements.

4. Network Management: The OLTs feature robust network management capabilities, including Quality of Service (QoS), traffic shaping, and bandwidth management. This ensures optimal performance and resource allocation across the network.

5. Security Features: The devices incorporate advanced security measures such as encryption, authentication, and access control to protect network data and prevent unauthorized access.

6. Redundancy and Reliability: The OLTs are designed with redundancy in mind, including dual power supplies and hot swappable components, to ensure minimal downtime and high reliability.

7. Scalability: The 16 port GPON interface board can be expanded as network demands grow, allowing for seamless scalability and future proofing of the network infrastructure.

8. Environmental Compliance: The OLTs are designed to meet stringent environmental standards, ensuring energy efficiency and reduced environmental impact.

9. Interoperability: The C++ module and GPON interface ensure compatibility with a wide range of network equipment and protocols, facilitating seamless integration into existing networks.

10. Support and Maintenance: ZTE provides comprehensive support and maintenance services for the ZXA10 series, ensuring ongoing performance and reliability.

In summary, the ZTE ZXA10 C600, C650, and C680 OLTs, with their 16 port GPON interface boards and C++ modules, offer a powerful and flexible solution for next generation broadband access networks. These devices are designed to deliver high speed data transmission, efficient network management, and robust security, all while being scalable and environmentally responsible.
