The "ZTE GFGM GPON OLT service card" is a component of a GPON (Gigabit Passive Optical Network) system, which is a type of fiber optic communication system used for broadband access. The OLT (Optical Line Terminal) is the central office equipment that manages the GPON network. Here's a brief introduction to the specification parameters of the ZTE GFGM GPON OLT service card:

1. GPON Standard Compliance: The card adheres to the ITU T G.984 series of standards, which define GPON technology.

2. Service Capacity: It supports a high number of GPON ports, typically ranging from 8 to 16 ports per card, allowing for extensive service coverage.

3. Data Rate: Each GPON port can support downstream rates of up to 2.488 Gbps and upstream rates of up to 1.244 Gbps.

4. Splitting Ratio: The OLT can support a splitting ratio of up to 1:64 or 1:128, which means one OLT can serve up to 64 or 128 ONUs (Optical Network Units) respectively.

5. Service Types: The card is capable of providing various services including internet access, VoIP (Voice over IP), IPTV (Internet Protocol Television), and other bandwidth intensive applications.

6. QoS (Quality of Service): It includes advanced QoS features to ensure that different types of traffic are prioritized according to their importance, providing a better user experience.

7. Security: The card incorporates security features such as encryption and authentication to protect data transmission.

8. Redundancy: To ensure high availability, the OLT service card may support redundancy features, allowing for failover in case of a card failure.

9. Management: It is equipped with management interfaces that allow for remote monitoring and configuration, simplifying network management.

10. Scalability: The OLT service card is designed to be scalable, allowing for the addition of more ports or cards as the network grows.

11. Power Efficiency: It is designed to be energy efficient, reducing operational costs.

12. Compatibility: The card is compatible with various types of ONUs and other network equipment, ensuring a smooth integration into existing networks.

13. Environmentally Friendly: It meets environmental standards and is designed to operate in a range of temperatures and conditions.

This overview provides a clear and distinct introduction to the key specification parameters of the ZTE GFGM GPON OLT service card, highlighting its capabilities and features in a concise manner.
