The "ZTE GFGL GPON OLT service card" is a component of a GPON (Gigabit Passive Optical Network) system, which is designed to provide high speed broadband access over fiber optic networks. Here's a concise introduction to its specification parameters:

1. Technology: GPON is a point to multipoint network architecture that uses a single optical fiber to serve multiple customers, offering high speed data transfer rates.

2. Service Card Role: The service card in an OLT (Optical Line Terminal) is responsible for managing the GPON services, including data transmission, service quality, and network management functions.

3. Data Rate: GPON typically supports downstream rates of up to 2.5 Gbps and upstream rates of up to 1.25 Gbps, although actual speeds can vary based on the specific implementation and network conditions.

4. Split Ratio: GPON systems can support a split ratio of up to 1:64, meaning one OLT can serve up to 64 ONUs (Optical Network Units) or end user devices.

5. Wavelength: The standard wavelengths for GPON are 1490 nm for downstream and 1310 nm for upstream, which are used to multiplex the signals onto a single fiber.

6. Service Types: The service card is capable of supporting various services, including internet access, VoIP (Voice over IP), IPTV (Internet Protocol Television), and other data services.

7. Quality of Service (QoS): The card supports QoS mechanisms to prioritize different types of traffic, ensuring that critical services like voice and video have the necessary bandwidth and low latency.

8. Security: GPON systems, including the service card, implement security measures such as encryption and authentication to protect data integrity and prevent unauthorized access.

9. Scalability: The service card is designed to be scalable, allowing for the addition of more users or services as the network grows.

10. Compatibility: It is designed to be compatible with industry standard GPON equipment and protocols, ensuring interoperability with a wide range of devices and systems.

11. Power Consumption: The service card is typically designed with energy efficiency in mind, minimizing power consumption while maintaining high performance.

12. Reliability: ZTE's service cards are engineered for high reliability, with features like redundancy and fault tolerance to ensure continuous service.

13. Management: The card is equipped with management interfaces that allow for remote monitoring and control, simplifying network administration and troubleshooting.

In summary, the ZTE GFGL GPON OLT service card is a critical component of a GPON system, offering high speed data services, support for multiple users, and advanced network management capabilities. It is designed to meet the demands of modern broadband networks with its robust performance and feature set.
