Huawei CGHF is a 16-port 10G GPON interface card
Basic information
Functional characteristics: Mainly used for OLT equipment, providing 16 10G GPON interfaces, which can achieve high-speed data transmission and access, meet the network needs of a large number of users, and are suitable for FTTH (fiber to the home), FTTB (fiber to the building) and other fiber access scenarios, and can provide users with high-speed and stable broadband access services.
Application scenarios: In the operator's access network, the CGHF card can be installed in the host frame of Huawei's MA5680T, MA5683T, MA5800 and other OLT equipment to provide home users and corporate users with broadband Internet access, IPTV, voice calls and other services.
Performance parameters
Port rate: Each port supports 10G Ethernet data transmission, which can meet the bandwidth requirements of future high-speed network development and provide users with ultra-high-speed network experience, such as supporting 4K/8K high-definition video, large-scale online games, virtual reality and other services with extremely high bandwidth requirements.
Split ratio: Supports a large split ratio, which can enable multiple users to access the same OLT The port access network effectively saves optical fiber resources and reduces network construction costs. The size of the split ratio can be flexibly configured according to the actual network planning and user distribution, and generally supports split ratio modes such as 1:64 and 1:128.
Transmission distance: Under single-mode optical fiber transmission conditions, it can support longer transmission distances, generally up to 20 kilometers or even farther, and can meet the network coverage requirements in different geographical environments, such as network access in remote areas and rural areas.
Use with other devices
Use with optical modules: It needs to be used with 10G GPON optical modules. The optical modules convert electrical signals into optical signals for transmission to achieve long-distance communication between OLT and ONU (optical network unit). Different types of optical modules may differ in transmission distance, optical power, etc., and the appropriate optical module needs to be selected according to the actual network environment.
Use with ONU: It is compatible with various models of Huawei ONU devices, such as HG8120, HG8240F, HG8346R and other optical modems, as well as enterprise-level ONU devices. OLT establishes a communication link with ONU through the CGHF board to provide network access services for users.
Working with routers or switches: After the OLT device is connected to the network through the CGHF board, it can be connected to network devices such as routers or switches to achieve network sharing and data exchange for multiple users. Routers can provide NAT conversion, firewall and other functions to ensure network security; switches can achieve LAN connection for multiple users and improve network data transmission efficiency.
