GPON MAC SFP ONU module, commonly known as "Cat Stick", is a specialized optical module that includes basic components such as BOSA, SOC, and RAM, enabling it to support modifying internal basic information. This architecture is equipped with the PON MAC function of ONU devices for the module, making it suitable for telecom grade FTTB, FTTH, and FTTO devices, mainly used for layer 2 devices.

In terms of its characteristics, the GPON MAC SFP ONU module stands out for its versatility and scalability. Its hot swappable design allows seamless integration into SFP slots of layer 2 Ethernet switches, network cards, routers, and other devices. Once inserted, the entire system can seamlessly connect to the GPON optical network as an ONT or even MDU. The OLT registration of modules in the central office follows a simplified process similar to configuring conventional optical cats, which helps with a smooth transition from P2P to PON network access. Based on the OMCI standard, it has a high-speed transmission rate of up to 1.25Gbps upstream and 2.5Gbps downstream.

The application of GPON MAC SFP ONU modules is diverse and innovative. The solution provided by Gigac demonstrates its potential in home gateway scenarios. By separating the GPON ONU portion from the hardware required by the application, these solutions can achieve independent upgrades to meet the evolving customer needs. In addition, when upgrading from GPON to 10G PON or even faster networks, only the relevant hardware components need to be replaced, greatly reducing operational and maintenance costs.

In summary, the GPON MAC SFP ONU module provides an efficient and flexible solution for fiber optic network access and upgrades with its unique functionality and adaptability. Its broad application prospects make it a valuable supplement to modern telecommunications systems.
