The "ZTE GFBL XG PON \u0026 GPON Combo Service Board" is a versatile component designed to support both XG PON (10 Gigabit Passive Optical Network) and GPON (Gigabit Passive Optical Network) technologies. This board is typically used in optical line terminals (OLTs) to provide high speed data services over fiber optic networks. Here's a concise introduction to its key specification parameters:

1. Technology Support: The board is designed to support both XG PON and GPON standards, allowing for backward compatibility and future proofing of the network infrastructure.

2. Data Rates: With XG PON, the board can support downstream rates of up to 10 Gbps and upstream rates of up to 2.5 Gbps. For GPON, it supports downstream rates of up to 2.5 Gbps and upstream rates of up to 1.25 Gbps.

3. Wavelength: The board operates on specific wavelengths for XG PON (1490 nm for downstream and 1577 nm for upstream) and GPON (1490 nm for downstream and 1310 nm for upstream).

4. Splitting Ratio: The board is capable of supporting various splitting ratios, which determine how many users can be served by a single OLT. Typical ratios range from 1:16 to 1:64 or higher.

5. Service Integration: It integrates multiple services such as internet access, VoIP, IPTV, and other data services over a single fiber connection.

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

7. Security Features: It includes security features such as encryption and authentication to protect data transmission over the network.

8. Redundancy and Reliability: The board may include features for redundancy, such as dual power supplies or hot swappable components, to ensure high availability and reliability of the service.

9. Management and Monitoring: It supports SNMP (Simple Network Management Protocol) or other management protocols for remote monitoring and management of the network.

10. Environmental Specifications: The board is designed to operate within specific temperature and humidity ranges, ensuring reliable performance in various environmental conditions.

11. Power Consumption: The board's power consumption is optimized to provide high performance with minimal energy usage.

12. Physical Dimensions: The board's dimensions are designed to fit within standard OLT chassis, allowing for easy integration into existing network infrastructure.

This board is a critical component for service providers looking to offer high speed broadband services while maintaining the flexibility to upgrade to newer technologies as they become available. Its specifications ensure that it can meet the demands of modern data services while providing a scalable and reliable solution for network expansion.
