Introduction to the five main types of ONU device

SFU (Single Family Unit) type ONU device

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.

SFU-24 (FE)0Optional
SFU-34 (FE)2Optional

HGU (Home Gateway Unit) ONU device

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.

HGU-14 (FE)011Optional
HGU-24 (FE)211Optional

MDU (Multi-Dwelling Unit) ONU device

This device mainly used for multiple residential users, with broadband access terminal function, multiple (at least 8) user-side interfaces (including Ethernet interface, ADSL2+ interface or VDSL2 interface), providing Ethernet/IP services and supporting VoIP services (built-in IAD) or CATV service, which mainly used in FTTB/FTTC/FTTCab.
According to the difference in service types and port numbers of the ONU, the form of the MDU-type ONU is shown in Table 3.

MDU-40012/16/24/3224/32/48/640

SBU (Single Business Unit) ONU device

The device mainly used for multiple enterprise users or individual users in the same area, with broadband access terminal function, multiple Ethernet interfaces (at least 8), E1 interface and POTS interface, providing Ethernet/IP services, TDM service and VoIP service (built-in IAD), which mainly used in FTTB/FTTBiz.
According to the difference between the service type and the number of ports of the ONU, there are two specific forms of the MTU-type ONU shown in Table 4.

Comprehensive comparison of EPON and GPON technology

1. EPON and GPON technology EPON  (Ethernet Passive Optical Network) is an Ethernet-based PON technology. It uses point-to-multipoint architecture, passive fiber transmission, and provides multiple services over Ethernet. GPON  (Gigabit-Capable PON) technology is the latest generation broadband passive optical integrated access standard based on ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, rich user interface, etc. Most operators regard it as an ideal technology for achieving broadband and integrated transformation of access network services. 2. EPON and GPON rate EPON provides fixed uplink and downlink 1.25 Gbps, 8b/10b line coding, and an actual rate of 1Gbps. GPON supports multiple speed grades, can support uplink and downlink asymmetric speed, downlink 2.5Gbps or 1.25Gbps, uplink 1.25Gbps or 622 Mbps.According to actual needs, the uplink and downlink rates are determined, and the corresponding optical modules are se

Introduction to the hierarchical model of GPON

GPON technical features are mainly reflected in the transmission convergence layer. The transmission aggregation layer is further divided into a PON frame sublayer and an adaptation sublayer. The framing sublayer of GTC (GPON Transmission Convergence) completes the ODN transmission function required for the encapsulation and termination of GTC frames. The specific functions of the PON (such as ranging, bandwidth allocation, etc.) are also terminated at the framing sublayer of the PON. The gametophyte layer is invisible. The adaptation sublayer of the GTC provides an interface between the PDU and the higher layer entity. The ATM and GEM information completes the conversion of the Service Data Unit (SDU) and the Protocol Data Unit PDU at the respective adaptation sublayers. The OMCI adaptation sublayer is higher than the ATM and GEM adaptation sublayers, which identify VPI/VCI and Port-ID and complete the exchange of OMCI channel data with higher-level entities. Application of GPON in

Frequently Asked Questions 1. What can I do if I cannot access the Internet? Answer: 1) Please confirm that the hardware connection is correct, whether the corresponding WAN and LAN lights are on, and whether the WAN and LAN lights are blinking (flashing indicates data transmission) to ensure the connection is valid. 2) In the bridge mode, whether the Internet can be accessed normally by dialing or other actual Internet access on the PC. If you can't get online: Please confirm that the PPP dialup software has been properly installed and completed. If can dial successfully, but still can't access the Internet, please confirm that the browser's proxy server settings are correct, and should be set to not use a proxy server;  Please try to log in to multiple websites to confirm that it is not caused by a website server failure;  Please try to disconnect the dial-up connection and dial again after 5 minutes. 3) If the Internet can be connected normally in the b
