Huawei EG8041V5 is a routing-type ONT in the Huawei all-optical access solution. It uses the GPON technology to implement ultra-broadband access for users. GPON replaces the traditional three-tier Ethernet design with a two-tier optic network which eliminates access and distribution Ethernet switches with passive optical devices. GPON is a point-to-multipoint fibre network architecture that allows multiple users to share a single optical fibre, reducing infrastructure costs while delivering high-speed connectivity. It is widely used in residential and business broadband services, supporting applications such as VoIP, IPTV.
