As modern fiber-to-the-home architectures expand into residential, commercial, and industrial environments, network engineers consistently face a critical bottleneck: power availability for user terminals. Traditional optical network units (ONUs) require local AC power outlets, forcing installers to handle complex electrical wiring, additional security compliance work, and high labor costs in locations with limited power.
To address this operational shortcoming, HSGQ introduced a groundbreaking series of PoF ONU, represented by the single-port HSGQ-F100P and the four-port HSGQ-F400P. HSGQ achieves a truly "power-free" architecture from central office to end-user by integrating optical data transmission and DC remote power supply into a hybrid optoelectronic cable.
Understanding Power over FiberTechnology
Power over Fiber technology in networks refers to the use of fiber-optic composite cables. These cables contain both optical fibers for high-speed broadband transmission and copper conductors for DC power transmission within a single sheath.
Why PoF is Superior to Traditional Power Supply Methods:
Longer Transmission Distance (Up to 300 Meters): Traditional Power over Ethernet (PoE) is limited to a physical copper cable transmission distance of less than 100 meters. HSGQ's PoF system can safely provide 48V–57V DC power within a 300-meter range, tripling the coverage.
No Local AC Power Required: Terminal ONUs draw power directly from the front-end/server room, eliminating the need for local power outlets, adapters, and transformer cabinets.
Higher Electrical Safety and Reliability: Eliminates the risk of high-voltage AC lines near end users and reduces the hazard of electric shock in damp or outdoor installation environments.
Core Enterprise Features and Operational Advantages
1. Integrated PoE Reverse Power Supply
The HSGQ PoF ONU can not only remotely receive operating power via hybrid cabling, but also function as a Power Provider Equipment (PSE). The ONU features PoE outputs compliant with the IEEE 802.3af/at standard, with up to 30W per port, directly powering downstream IP cameras, wireless access points (APs), VoIP phones, or smart sensors without the need for an auxiliary power injector.
2. Dual-Mode GPON/EPON Adaptive Design
Both the F100P and F400P adopt a universal PON compatibility design, automatically detecting and adapting to GPON or EPON optical line terminal (OLT) environments. This versatility protects ISPs' infrastructure investments and simplifies inventory management for network operators.

3. Enterprise-Grade Traffic Control and Security
The HSGQ PoF ONU integrates comprehensive Layer 2/Layer 3 networking features, including:
VLAN Management: Supports VLAN pass-through, tagging, translation, relaying, and QinQ.
Multicast and QoS: IGMP multicast snooping, IEEE 802.1p CoS prioritization, and WR/SP queue scheduling.
Security and Diagnostics: Broadcast storm suppression, Ethernet port rate limiting, user-side loopback detection, and full IPv4/IPv6 dual-stack support.
4. Intelligent Cloud and OMCI Management
Remote maintenance is crucial for reducing operating costs (OPEX). HSGQ PoF terminals support OMCI protocol configuration via OLT and seamlessly integrate with the HSGQ cloud management platform, enabling administrators to remotely perform batch firmware upgrades, status monitoring, and port rate limiting.
Target Application Scenarios
Smart Cities and Security Monitoring: Deploy IP cameras on highway poles or building facades within 300 meters of power sources without laying expensive wiring conduits.
Fiber to the Home and Multi-family Residences: Provide ultra-high-speed fiber broadband to apartments while eliminating power access issues in common corridors or shafts.
Enterprise and Campus Wi-Fi Extension: Easily install ceiling-mounted APs or outdoor wireless bridges; HSGQ PoF ONUs can handle both gigabit backhaul and PoE power supply simultaneously.
