Choosing a Huawei CGHF board that suits your needs requires comprehensive consideration of many factors. Here are some suggestions:
Number of ports
Demand analysis: Determine the number of ports based on the number of users or devices that need to be connected. If it is a small business or home network with a small number of users and low port demand, the conventional number of ports may be sufficient to meet the demand; while for large enterprises, campus networks, or access networks of telecom operators, etc., which need to connect a large number of user terminals or lower-level network devices, more ports may be required to meet access needs.
Matching suggestion: Huawei CGHF boards are generally 16-port XGPON service boards. The number of boards required can be calculated based on the actual number of users and future expansion needs. For example, if an enterprise expects that the number of user terminals will not exceed 200 in the next three years, and each user terminal needs to access the network, considering a certain degree of redundancy, 2-3 16-port CGHF boards can be selected.
Service type and bandwidth requirements
Demand analysis: Different services have very different requirements for network bandwidth and performance. For example, ordinary web browsing, e-mail and other services require relatively low bandwidth, and generally each user can meet the demand with a bandwidth of several megabytes to more than ten megabytes; while video conferencing, high-definition video playback, online games and other services require higher bandwidth, and each user may need tens of megabytes or even hundreds of megabytes of bandwidth. In addition, some special business applications, such as virtual reality (VR) and augmented reality (AR), have higher requirements for bandwidth and network latency.
Matching suggestion: Huawei CGHF board, as an XGPON service board, can provide higher upstream and downstream bandwidth, with a downstream rate of up to 10Gbps and an upstream rate of up to 2.5Gbps. If the network is mainly low-bandwidth services, then a board can support a relatively large number of users; conversely, if there are a large number of high-bandwidth business requirements, it is necessary to reasonably evaluate the number of boards and splitting ratios to ensure that each user can obtain sufficient bandwidth. At the same time, you can also combine the Quality of Service (QoS) strategy to prioritize and control the flow of different services to optimize the allocation of network resources.
Split ratio
Demand analysis: The split ratio determines the number of optical network units (ONUs) that can be connected to a port and the optical power obtained by each ONU. When selecting the split ratio, you need to consider factors such as network coverage, user distribution density, and optical fiber resources. If the user distribution is relatively concentrated and close to the OLT device, you can choose a larger split ratio to improve the utilization of network resources; if the user distribution is relatively scattered or far away from the OLT device, you need to choose a smaller split ratio to ensure that each ONU can obtain sufficient optical power to ensure signal quality and transmission distance.
Matching suggestions: Common split ratios are 1:8, 1:16, 1:32, 1:64, etc. Taking the splitting ratio of 1:32 as an example, a 16-port CGHF board can connect up to 16×32 = 512 ONUs. However, as the splitting ratio increases, factors such as optical power budget and transmission distance need to be considered comprehensively to ensure the normal operation of the network.
Compatibility
Requirement analysis: Ensure that the CGHF board is compatible with existing Huawei OLT device models. Different models of OLT devices may have different support for the board. In addition, compatibility with other network devices such as switches and routers needs to be considered to ensure the stable operation and interconnection of the entire network system.
Matching suggestion: Huawei CGHF board is suitable for OLT device series such as MA5800, MA5680T, MA5683T, MA5608T, etc. When selecting, it is necessary to match according to the existing OLT device model.
