The ZXHN F780L is an AC1200 dual band Gigabit Premium triple- play GPON gateway.It comes with 1GE&3FE LAN ports, one phone port and next generation multi-stream Wi-Fi, operating simultaneously in 2.4GHz 2x2 over 802.11n and 5GHz 2x2 over 802.11ac. Based on customer requirements, the maximum 5dBi gain antennas can enhance the Wi-Fi coverage area and improve the performance.
1.Plug-and-play: services can be deployed by one click on the NMS, and on-site configuration is not required. 2.Remote diagnosis: Remote fault locating is implemented by the loop-ine test of POTS ports,call emulation and PPPOEdialup emulati. 3.Link monitoring: E2E link detection is achieved using 802.1ag Ethernet OAM. 4.High speed forwarding: 900 Mbit/s forwarding in the NAT scenario. 5.lPv6 Capability: support IPv6/Pv4 dual stack and DS-Lite.
What is an ONU?
ONU, also known as an Optical Line Terminal, is one of the essential devices required for internet connectivity. Its function is to convert optical signals from optical fibers into digital signals. This conversion is necessary because devices such as PCs and smartphones cannot directly process optical signals. Conversely, digital signals sent from devices like PCs and smartphones need to be converted by the ONU into optical signals before being transmitted to the internet. Typically, the ONU is leased from a contracted line operator.
How does an ONU work?
On the network side, the ONU receives data from the Optical Line Terminal (OLT) via a Passive Optical Network (PON) and delivers it to end-user devices. On the user side, it converts optical signals into electrical signals and vice versa, enabling bidirectional communication. It also performs signal processing, maintenance, and management functions to ensure a reliable and stable connection.
Features of ONU
To better understand its functions, here are the key features of an ONU:
Triple Play Services: Supports data, IPTV, and VoIP services, catering to the needs of both residential and commercial users.
Bidirectional Data Transmission: Receives broadcast data from the OLT while sending back user-generated data through assigned transmission windows.
Ethernet Data Buffering: Temporarily stores Ethernet data before transmitting it to the OLT, optimizing data flow.
Remote Management via OAM: Enables remote Operation, Administration, and Maintenance (OAM), allowing service providers to monitor and configure ONUs efficiently.
Security and Quality of Service (QoS): Many ONUs offer enhanced security features and Quality of Service (QoS) support, ensuring reliable performance for different applications.
Applications of ONU
RF/CATV Port: Used for connecting to cable television.
Power Interface: Provides power connectivity.
USB Port: Typically a USB 2.0 interface.
LAN Port: Supports FE (10/100BASE-T) or GE (10/100/1000BASE-T) options.
Telephone Port: Also known as POT, VoIP, Voice, or FXS port.
Optical Port: Connects to the Optical Distribution Network (ODN).
