Difference between SFU and HGU

Hello,

Please be informed that
SFU (Switch Fabric Unit): Bridge ONT (HG8010, etc.)
HGU (Home Gate Unit): Gateway ONT (HG824X, etc.)

Thanks

Hello friend！
HGU is a home gateway-type ONU, supports three-layer functions, can be easily internal network, support multiple users to communicate
SFU is an ordinary onu, equivalent to a Layer 2 switch, and only supports each user to access the Internet

HGU supports WIFI function.
SFU usually does not support WIFI function.

Thank you！

Hello there！
From a construction perspective, SFU cannot be coupled across vendors. The ONU of various manufacturers can only take their own independent OLT. As a unified specification ONU, HGU can be coupled with each other, and there is no incompatibility.

hello dear i hope it will help you

Optical termination unit type SFU (Single Family Unit) and HGU (Home Gateway Unit) are used to terminate optical access networks.

SFU’s also can include full residential gateway (sometimes called Home Gateway (HG)) with firewall, NAT router – which then eliminates a need for a subscriber to install it’s own WiFi router to distribute internet in home or office, DHCP server, USB ports, storage or print server and more. This form of SFU then requires a customer cooperation to manage and configure it and thus more support personnel will be required from a operator side. For this, also TR-69 standard must be supported by SFU Home Gateway units.

SFU (Single Family Unit) 

Mainly used by individual home users, which only supports broadband access terminal function, the device has 1 or 4 Ethernet interfaces, providing Ethernet/IP services,supporting VoIP service (built-in IAD) or CATV service. It mainly used in FTTH occasions ( also can be used with a home gateway to provide greater business capabilities).

According to the difference between the service type and the number of ports of the ONU, there are three specific forms of the SFU-type ONU shown in Table 1.

HGU (Home Gateway Unit)
This mainly used for individual home users, with home gateway function, equivalent to home gateway with EPON uplink interface, with 4 Ethernet interfaces, 1 WLAN interface and at least 1 USB interface, providing Ethernet/IP services, which can support VoIP or CATV service and TR-069 remote management. The device mainly used in FTTH solutions.
According to the difference between the service type and the number of ports of the ONU, there are two specific forms of the HGU-type ONU shown in Table 2.
