All productsIn Huawei’s telecommunications infrastructure, ASPB boards play a vital role in delivering broadband services to end-users. These boards are designed to suit various platforms and network environments, ensuring efficient service delivery based on the existing infrastructure.
However, based on customer feedback and experiences, there is often confusion regarding the ASPB boards for different platforms. To clarify and help you better understand, this article will walk you through two key ASPB boards: H809ASPB and H838ASPB.
Introduction to H809ASPB and H838ASPB:
H809ASPB is a 64-port VoIP subscriber board, providing 64 channels of VoIP POTS access services. It is designed for use in the MA5600T OLT, which is Huawei’s high-capacity Optical Line Terminal for fiber-based access networks. MA5600T OLT is primarily deployed in Fiber-to-the-Home (FTTH) or Fiber-to-the-Building (FTTB) networks, where it manages the optical connections between the core network and the end-user Optical Network Terminals (ONTs).
H838ASPB is a 64-channel POTS service board, providing 64 channels of POTS access service. On the other hand, it is used in the MA5616 DSLAM, a platform designed for copper-based networks. The MA5616 DSLAM is typically deployed in areas where Digital Subscriber Line (DSL) services are still widely used, relying on existing twisted-pair copper infrastructure.
Differences between H809ASPB and H838ASPB:
Let’s take a closer look at differences on specification between these two boards.
| H809ASPB | H838ASPB | |
| Platform | MA5600T OLT | MA5616 DSLAM |
| Application | Fiber-based networks, primarily for FTTH/FTTB deployments | Copper-based networks, primarily for DSL broadband access |
| Connector type | Delander 64-pin | Champ 64-pin |
| Network Technology | Passive Optical Network (PON) – GPON, 10G GPON | xDSL – VDSL2, ADSL2+, POTS |
| Interface Types | Optical interfaces for PON ports | DSL interfaces for twisted-pair copper lines |
| Bandwidth Capacity | Gigabit-level speeds (hundreds of Mbps to multiple Gbps) | Up to 100 Mbps with VDSL2 |
| Service Capabilities | High-bandwidth services: 4K/8K video, cloud computing, etc. | Standard broadband, video streaming, VoIP |
| Deployment Use Case | FTTH/FTTB networks, urban areas with fiber infrastructure | Copper-based broadband in suburban/rural areas or regions not yet upgraded to fiber |
| Scalability | High scalability for future bandwidth demands | Limited scalability, constrained by copper infrastructure limitations |
| Typical Environment | High-demand environments with ultra-fast internet needs | Cost-effective broadband deployment over existing copper lines |
Understanding the distinct characteristics and deployment scenarios of these boards is crucial for you seeking to optimize your network infrastructure based on available resources and subscriber needs.
