H66G FTTH Wi-Fi 6 Optical Network Terminal (ONT) Product Description

1. Product Overview

The H66G is a high-performance, routing-type Optical Network Terminal (ONT) designed for Fiber-to-the-Home (FTTH) and SOHO applications. It integrates GPON access, dual-band Wi-Fi 6 (802.11ax), Gigabit Ethernet, VoIP, and USB functions into a single device, delivering ultra-broadband, stable, and secure voice, data, and video services.

 

 

2. Key Features

• GPON Access: Compliant with ITU-T G.984 standards, supporting downstream 2.488 Gbps and upstream 1.244 Gbps.
• Wi-Fi 6 (AX) Technology: Dual-band 2.4 GHz & 5 GHz concurrent, delivering faster speed, lower latency, and higher device capacity.
• 4 × Gigabit Ethernet (GE) Ports: Auto-sensing 10/100/1000 Mbps RJ45 ports for wired devices.
• 1 × POTS (VoIP) Port: Supports analog telephone service and fax.
• 2 × USB 2.0 Ports: For network storage (NAS), printer sharing, and media sharing (DLNA/SAMBA).
• 4 × External High-Gain Antennas: Enhanced Wi-Fi coverage and signal stability.
• Advanced Security: Firewall, WPA3 encryption, MAC address filtering, and access control.
• QoS & Multicast: Traffic prioritization, IGMP v2/v3 snooping for IPTV/HD video.
• Easy Management: Web GUI, OMCI, and TR-069 remote management.
• Energy Efficient: Low power consumption design.
