In fiber optic access network deployments, the selection of appropriate terminal equipment directly impacts network costs, deployment efficiency, and equipment integration.
Revolutionizing FTTx Deployment: How HSGQ Power over Fiber (PoF) ONUs Solve the Last Mile Power Problem. Learn how the HSGQ-F100P and HSGQ-F400P PoF ONUs transmit optical data and DC power up to 300 meters via hybrid optical cables, and feature 30W PoE output and cloud management capabilities.
HSGQ Power over Fiber (PoF) products combine optical data transmission with remote power delivery through a fiber-based connection. This approach helps network operators connect devices in locations where installing separate electrical wiring, power outlets, or adapters is difficult.
Our PoF product range includes optical routers, fiber optic ceiling access points, and PoF ONUs for FTTH, hotels, apartments, school campuses, office parks, medical facilities, and other all-optical network deployments. By centralizing power and network management, PoF can simplify installation, improve endpoint flexibility, and reduce the complexity of maintaining distributed network equipment.
HSGQ provides three primary PoF product types for building an integrated optical access network. Each device performs a different role, from centralized power and data management to wireless coverage and user-side network access.
The PoF Optical Router serves as the central control, data forwarding, and power distribution device in a Power over Fiber network. It connects to the upstream network and provides fiber-based data transmission and centralized power delivery to remote ONUs, ceiling APs, and other compatible endpoints.
A fiber-optic composite connection can carry network data and power to remote devices without requiring a separate local power adapter at every endpoint. Depending on the model, the router may support multi-gigabit forwarding, Layer 3 routing, cloud management, QoS scheduling, and centralized monitoring.
Selected models also include protection functions such as overcurrent, overvoltage, short-circuit, reverse-connection, and surge protection. These features help improve the reliability of centralized power delivery in FTTR, campus, hotel, and office network projects.
At the center of the network, the PoF Optical Router manages data forwarding and centralized power delivery for remote ONUs and ceiling APs.
The PoF Optical Ceiling AP is designed to provide wireless coverage in locations where installing a power outlet or high-voltage wiring near the ceiling is inconvenient. It receives both network data and power through a compatible PoF fiber connection, allowing the access point to operate without a separate local power adapter.
HSGQ PoF ceiling APs support Wi-Fi 6 technology on selected models, including features such as OFDMA, MU-MIMO, dual-band operation, and seamless roaming. Wireless throughput and coverage vary by model, antenna design, deployment environment, and the number of connected users.
A PoF ceiling AP is suitable for hotels, apartments, offices, classrooms, corridors, conference areas, and other indoor spaces that require consistent wireless coverage. When deployed with a PoF Optical Router, multiple APs can be managed through a centralized network architecture and unified wireless settings.
For wireless coverage in areas where local power outlets are difficult to install, the PoF Optical Ceiling AP receives both data and power through a compatible PoF connection.
The PoF ONU is the user-side endpoint of a Power over Fiber access network. It receives the incoming optical connection, converts the optical signal into Ethernet or wireless network access, and uses the power delivered through the PoF link instead of relying on a separate local power adapter.
HSGQ PoF ONUs are available in different housing formats, including compact desktop and wall-mounted designs. Depending on the model, they may support EPON, GPON, or XPON access, gigabit Ethernet, dual-band Wi-Fi 6, VLAN configuration, QoS management, and centralized cloud-based management.
A wall-mounted PoF ONU can help reduce visible cabling and free up wall sockets in apartments, hotel rooms, offices, dormitories, and other rooms with limited installation space. Model selection should be based on the required PON standard, Ethernet ports, wireless functions, power budget, cable distance, and network management requirements.
At the user side, the PoF ONU converts the incoming optical signal into Ethernet or Wi-Fi access while using power delivered through the PoF link.
Power over Fiber is a technology that uses a fiber-based connection to transmit network data and power to a remote device. Instead of installing a separate fiber cable for data and electrical wiring for power, a PoF system centralizes the power source and delivers the required energy to compatible endpoints through the optical network architecture.
In a typical PoF deployment, the process includes the following steps:
1. Power conversion at the central device
The PoF Optical Router or central power equipment receives electrical power and converts it into a form that can be delivered through the PoF link.
2. Fiber-based transmission
The network data and power are transmitted through a dedicated optical or fiber-optic composite connection to the remote endpoint. The exact cable structure and transmission method depend on the PoF system design and product model.
3. Remote power conversion
At the receiving end, a photovoltaic receiver, photoelectric conversion module, or compatible PoF ONU converts the incoming optical energy into usable electrical power for the device.
4. Network access at the endpoint
The remote ONU or ceiling AP uses the received power to provide Ethernet or wireless connectivity to users and connected devices.
The complete system must be designed according to the endpoint power requirement, cable length, optical loss, bandwidth, connector type, and environmental conditions.
PoF reduces the need to install separate network and electrical connections to every remote endpoint. This can be especially useful for ceiling-mounted APs, wall-mounted ONUs, and remote network equipment.
Power is supplied from a central equipment room or network cabinet. When connected to a UPS-backed power system, the central power architecture can also support more consistent protection for compatible remote devices.
PoF is useful in ceilings, corridors, hotel rooms, offices, campuses, and other locations where adding power outlets or high-voltage wiring may increase construction difficulty.
Because a compatible PoF ONU or ceiling AP does not require a separate local adapter, the final installation can have fewer visible cables, fewer wall-mounted power supplies, and a cleaner appearance.
A PoF Optical Router can centralize network configuration, traffic management, QoS policies, and selected endpoint monitoring functions. This helps network administrators manage multiple PoF devices from a more organized architecture.
PoF products can be deployed in homes, hotels, offices, campuses, and other multi-room environments. The final solution can be scaled according to the number of ONUs, APs, rooms, floors, and network users.
A practical PoF network usually includes the following components:
1. Upstream network connection
The PoF system connects to the upstream access network, OLT, or other network equipment according to the project architecture.
2. Central PoF Optical Router
The central router manages data forwarding and distributes power to compatible remote endpoints.
3. Fiber-optic composite connection
The connection runs from the central equipment room to the target room, ceiling, access point, or user-side location. Cable type, distance, connector configuration, and power budget should be confirmed during solution design.
4. Remote endpoint
A PoF ONU provides Ethernet or wireless access for users, while a PoF ceiling AP provides Wi-Fi coverage. Different endpoint types may require different power and bandwidth levels.
5. Network management system
Depending on the product model, the system may support cloud management, VLAN configuration, QoS scheduling, remote monitoring, and centralized maintenance.
The system architecture should always be matched to the actual project requirements. Port count, PON standard, Wi-Fi capacity, endpoint quantity, cable length, installation environment, and local compliance requirements can all affect product selection.
PoF can help extend fiber-based connectivity to rooms and indoor wireless access points while reducing the need for separate power adapters. It is suitable for multi-room homes, apartments, and residential buildings.
Hotel rooms, corridors, public areas, and apartment buildings often require reliable wireless access but may have limited space for additional power outlets. PoF ONUs and ceiling APs can support a more organized room-by-room deployment.
PoF products can be used to connect classroom, dormitory, office, and public-area endpoints. Centralized power and network management can simplify the operation of multiple wireless access locations.
PoF supports fiber-based access to offices, meeting rooms, corridors, and shared workspaces. It can help reduce visible cabling and provide flexible access point deployment.
Medical environments may require reliable connectivity, organized cabling, and careful equipment installation. PoF can support fiber-based network access in rooms and areas where remote electrical wiring should be minimized.
PoF is suitable for ceiling spaces, remote rooms, temporary installations, and other areas where providing a local electrical connection would increase installation time or maintenance complexity.
Before selecting Power over Fiber equipment, consider the following factors:
Choose a PoF ONU for user-side Ethernet or wireless access, a PoF Ceiling AP for indoor Wi-Fi coverage, or a PoF Optical Router for centralized control and power distribution.
Check whether the deployment requires EPON, GPON, XPON, or another access standard. The ONU and upstream network equipment must be compatible.
Consider the number of connected users, required Ethernet speed, wireless throughput, uplink capacity, and expected traffic growth.
The total power requirement depends on the number and type of connected endpoints. Confirm the available power budget of the PoF router and the power consumption of each ONU or AP.
The transmission distance depends on the cable type, optical loss, connector configuration, endpoint power requirement, and product specifications. HSGQ can recommend a suitable configuration after reviewing the project parameters.
Review whether the device will be ceiling-mounted, wall-mounted, installed in a cabinet, or placed on a desktop. Housing size, ventilation, temperature, dust, and maintenance access should be considered.
For multi-device projects, cloud management, VLANs, QoS, remote monitoring, traffic control, and centralized configuration can improve long-term operation.
HSGQ develops and manufactures optical communication equipment for fiber access networks and related deployment scenarios. The company provides PoF routers, ceiling APs, ONUs, OLTs, switches, SFP modules, and other network products that can be combined according to project requirements.
HSGQ supports product development, OEM/ODM customization, technical consultation, and after-sales assistance. For international projects, the required certifications, firmware functions, network compatibility, and product configuration should be confirmed according to the destination market and specific model.
When requesting a PoF solution, customers can provide the following information:
Number and type of remote endpoints
Required PON standard
Required Ethernet and Wi-Fi speed
Estimated cable distance
Number of rooms, floors, or coverage areas
Installation environment
Required management functions
Destination country and certification requirements
This information allows the product configuration and power budget to be evaluated more accurately.
In many cases, PoF can be integrated into an existing fiber access architecture by adding a compatible PoF router and PoF endpoints. However, compatibility depends on the upstream OLT, PON standard, optical budget, management protocol, and endpoint requirements. HSGQ should review the existing network structure before confirming the final configuration.
Yes. A PoF deployment must use cables, connectors, and interfaces that are compatible with the selected power and data transmission architecture. Standard passive fiber components may not be suitable for carrying the required power. Cable type, connector structure, optical loss, mechanical protection, and installation conditions should be confirmed before construction.
Yes. PoF and PoE can coexist at different points in the same network. For example, PoF may be used to deliver power and data from the central equipment room to a remote ONU or ceiling AP, while the endpoint may use PoE to connect and power local cameras, phones, or other Ethernet devices. The power path must be planned carefully to avoid exceeding the available power budget.
A properly designed PoF network can isolate a fault at the affected endpoint while keeping other network devices operational. The actual behavior depends on the router’s protection functions, port design, power allocation, and management system. Overcurrent, short-circuit, and temperature protection can help reduce the impact of an individual endpoint fault.
The total power requirement should include the rated consumption of every connected ONU, ceiling AP, or other PoF endpoint. The calculation should also consider startup power, cable loss, operating temperature, future expansion, and a reasonable safety margin. Selecting a router only by the number of ports may result in insufficient power capacity.
PoF products can support future upgrades when the original design leaves sufficient bandwidth, power, port, and management capacity. Before replacing an endpoint with a higher-performance ONU or Wi-Fi access point, confirm that the PoF router, cable system, power budget, firmware, and upstream network can support the new device.
PoF can be used in selected outdoor or industrial applications, but the equipment and cable must be designed for the actual environment. Temperature range, moisture, dust, UV exposure, mechanical stress, lightning protection, enclosure rating, and connector protection should all be evaluated before deployment. Indoor PoF equipment should not be installed outdoors without confirming its environmental rating.
Compatibility depends on the specific product and network architecture. Important factors include EPON, GPON, or XPON support, Ethernet interfaces, VLAN functions, management protocols, firmware behavior, optical specifications, and power delivery requirements. HSGQ can evaluate the existing OLT, router, ONU, or switch information before recommending a compatible PoF configuration.
