Next-Gen GPON Optical Network
– Powered by SONiC & OLT Stick SFP Module

Solution Overview

As campuses and small to medium-sized enterprises (SMEs) embrace smarter, more connected digital environments, traditional Ethernet access networks are reaching their limits, struggling to keep pace with the rising demands for bandwidth, flexibility, and scalability.

Asterfusion introduces a future-ready approach that combines GPON OLT stick SFP modules with open SONiC enterprise switches, creating a fully optical, open, and cost-efficient access architecture.

Asterfusion’s solution provides:

  • Plug-and-play PON: Modular, hot-swappable OLT stick SFP modules deliver GPON capability directly on Asterfusion SONiC switches—no standalone OLT needed.
  • Massive scalability: Each SONiC switch’s SFP port supports up to a 1:128 split ratio, connecting up to 128 ONTs or APs from a single port.
  • Centralized management: Unified management and automated configuration of both wireless and wired devices via an OpenWiFi-compatible controller.
  • Cost efficiency
    • Initial equipment investment reduced by 18–58% compared to traditional OLT deployments.
    • Significant hidden savings from reduced rack space, lower energy consumption, and simplified maintenance

Asterfusion GPON Campus Access Connectivity Scenario

Scenario 1: Asterfusion GPON Campus Network with OLT SFP Modules

When upgrading traditional GPON access networks, Asterfusion OLT stick SFP modules can replace traditional OLT devices, delivering the same GPON capabilities with significantly reduced costs and footprint. This is ideal for universities, enterprises, and institutions seeking simplified network infrastructure.

Each CX202P-24S-M-H SONiC switch provides 24 single 10G optical ports, and by adjusting the optical distribution network (ODN) split ratio—8, 16, or 32 splits per port—it supports progressively larger numbers of APs.

Scenario

  • Recommended split ratio: 2.5G → 1:8
  • Recommended split ratio: 10G → 1:32

As shown below, a single CX202P-24S-M-H switch supports up to 24 ODNs, making it suitable for extensive deployments. Using 14 x CX202P-24S-M-H switches, the network can manage a total of 336 ODNs at the ODN layer.
Each ODN connects up to 32 APs with a 1:32 split ratio, supporting up to 10,752 APs in total. With each AP delivering an average of 300 Mbps bandwidth, this setup easily meets the demands of high-density environments.
