ZTE ZXHN F673A V2 GPON ONT 4x GE,1x POTS, 1x USB, WiFi AC Dual Band

ZTE F673A V2 GPON ONT with 4× Gigabit Ethernet, WiFi, USB, POTS and CATV

ZTE F673A V2 is an advanced GPON ONT subscriber terminal designed for use in FTTH fiber-optic networks for home users, small businesses and SOHO installations. The device combines the functions of an optical terminal, network gateway, WiFi access point, telephony gateway and CATV interface.

Thanks to GPON technology, the terminal provides broadband Internet access and supports services such as VoIP, IPTV and HD video transmission. Its interfaces include 4 Gigabit Ethernet ports, 1 POTS port, a USB 2.0 port, WiFi and an RF CATV port.

GPON technology

The ZTE F673A V2 is equipped with 1 GPON port with an SC/UPC connector, designed to connect the device to the operator's fiber-optic infrastructure.

The terminal uses Class B+ optics and supports features including FEC and dynamic bandwidth allocation (DBA). Authentication of the terminal in the GPON network can be performed using the serial number (SN) or a password, in accordance with the mechanisms specified in the ITU-T G.984.3 standard.

Optical interface parameters

The GPON interface operates at a wavelength of 1310 nm for upstream and 1490 nm for downstream transmission.

The terminal supports, among others:

• Class B+ GPON optics,
• receiver sensitivity down to -27 dBm,
• upstream wavelength: 1310 nm,
• downstream wavelength: 1490 nm,
• WBF wavelength blocking filter,
• flexible mapping between GEM Port and T-CONT,
• authentication using SN or password,
• bidirectional FEC error correction,
• SR-DBA and NSR-DBA.

4 Gigabit Ethernet ports

The ZTE F673A V2 features 4 auto-negotiating Gigabit Ethernet ports, allowing wired connection of computers, TVs, set-top boxes, gaming consoles, switches and other network devices.

The Ethernet ports support, among others:

• 1:1 VLAN,
• N:1 VLAN,
• transparent VLAN transmission,
• QinQ VLAN,
• VLAN tag addition and removal,
• MAC address learning,
• MAC address learning limit,
• transparent Layer 2 transmission of IPv6 packets.

2.4 GHz WiFi

The terminal features an integrated WiFi access point operating in the 2.4 GHz band. It uses 2x2 MIMO technology to improve the efficiency of communication with wireless devices.

The ZTE F673A V2 supports IEEE 802.11b/g/n standards as well as a range of functions useful in everyday wireless network operation.

Available features include:

• 2x2 MIMO,
• 2 dBi antenna gain,
• WMM,
• multiple SSID support,
• WPS.

POTS telephone port

The device is equipped with 1 POTS port, allowing an analog telephone to be connected for use with VoIP services.

The terminal supports the following voice codecs:

• G.711A/μ,
• G.729a/b,
• G.722.

Telephony functions also include support for DTMF, fax transmission in T.30/T.38/G.711 modes and emergency calls using the SIP protocol.

The maximum REN value is 4.

RF CATV port

One of the additional features of the ZTE F673A V2 is an RF CATV interface, designed to carry cable television signals.

The port supports a frequency range of 54 to 870 MHz and has an output impedance of 75 Ω.

Interface parameters include:

• frequency range: 54–870 MHz,
• output impedance: 75 Ω,
• average received optical power: -8 to +2 dBm,
• RF output power: ≥17 dBmV/Ch under specified RF source input conditions.

USB 2.0 port

The ZTE F673A V2 features 1 USB 2.0 port, which can be used to connect compatible USB devices.

The terminal also supports an FTP-based network storage function, allowing data stored on a connected storage device to be shared over the network.

Triple Play service support

The extensive range of interfaces available on the ZTE F673A V2 makes it possible to use a single terminal for multiple services delivered by an operator.

The device can be used to provide Triple Play services, including:

• high-speed Internet access,
• VoIP telephony,
• television and video transmission.

By combining GPON, Ethernet, WiFi, POTS, USB and CATV functionality, the terminal can serve as the central communications device in a home or small office.

VLAN and Ethernet functions

The ZTE F673A V2 provides a broad range of Ethernet and VLAN traffic management functions. These include VLAN tag assignment and removal, transparent VLAN transmission and QinQ support.

These functions make it possible to logically separate different types of traffic and can be used by operators to separate Internet, VoIP and other services delivered over an FTTH network.

Compact design

The ZTE F673A V2 has a compact enclosure measuring 220 × 160 × 32 mm, making it easy to install in homes and small SOHO environments.

The terminal is designed as a multifunctional access gateway that helps reduce the number of separate devices required to provide fiber-optic services.
