Outdoor Wireless Coverage
Outdoor and corridor Wi-Fi APs need a data link, a power source and a mounting point. PoF combines the first two over one hybrid cable to 200 m, which is often the difference between a clean ceiling install and a new mains spur.

The engineering problem
Why the obvious answer fails.
The endpoint is small; the distance, the power and the environment are not. Three paragraphs explain where the design usually breaks.
An outdoor AP is usually mounted where the network is not: a pole, a roof edge, a far corridor, a car park. The data cable can reach it, but the power socket cannot. Running a mains spur to each AP adds an electrician, a conduit, a weatherproof box and a surge path; on a large site it can cost more than the AP.
Distance is the second issue. A PoE run is limited to 100 m; a car park or a long corridor easily exceeds it. A PoE extender solves the distance but still needs power at the mid-point, which is often the same problem moved 100 m away.
PoF removes both constraints in one cable: one fibre for data and one copper pair for 48 V DC, up to 200 m and 12 W per port. For a Wi-Fi 6 AP drawing 10–15 W, that is enough; for a high-power outdoor AP with a heater, it is not, and the design should use a local switch or a higher-power cabinet.
Path comparison
Four paths, one decision.
The correct path is the one that matches the endpoint power, the distance and the presence of mains. Do not compare only on cable price.
| Path | Reach | Power at the endpoint | Mains at endpoint | Best for | Limits |
|---|---|---|---|---|---|
| Copper PoE | 100 m channel | 15.4 / 30 W at the source (af / at) | Required for the switch | Devices within 100 m of a powered cabinet | Cable loss, surge path, no reach beyond 100 m |
| PoE extender | 200 – 500 m with hops | Reduced at each hop | Required at every extender | Retrofit where a mid-point has power | Another powered box outdoors; still copper |
| Power over Fiber | Up to 200 m per port | Up to 12 W per port | Not required | Ceiling APs, pole cameras, readers, sensors | 12 W per port, hybrid cable, 200 m limit |
| Fibre + local PoE switch | 20 km PON backhaul | Local switch budget | Required at the local cabinet | Cabinets, buildings, dense clusters | Needs a powered cabinet and a switch |
The correct path is the one that matches the endpoint power, the distance and the presence of mains. Do not compare only on cable price.
Design approach
How we lay it out.
Map the AP load and the mounting points
Record the AP model, PoE class, nominal and peak draw, mounting height and distance to the nearest cabinet. A Wi-Fi 6 AP is usually 10–15 W; an outdoor AP with a heater can be 25 W or more.
Check the 200 m and 12 W envelope
If the run is under 200 m and the load under 12 W, a PoF splitter plus a PoF ONU/AP is the cleanest path. Keep 20% headroom for cable loss and radio peak.
Use the ceiling ONU as the AP
The PoF ceiling ONU is a Wi-Fi 6 AX3000 access point with a PON uplink. It is managed by the gateway/OLT and supports zero-touch provisioning and roaming, so no local controller is needed.
Bill of materials
A starting BOM.
Quantities follow the endpoint count and the number of cabinets. Adjust after the site survey.
| Item | Specification | Quantity basis |
|---|---|---|
| Optical gateway / OLT | 1× GPON + 2× GE + 1× 10GE SFP+ | 1 per building or floor group |
| PoF power splitter | 1×9, 8 outputs, 120 W supply | 1 per 8 APs |
| Hybrid PoF cable | G.657A2 + copper, 20/50 m | 1 per AP + 10% spare |
| PoF ceiling ONU / AP | Wi-Fi 6 AX3000, 1× GE | 1 per coverage cell |
| Mounting kit | Ceiling or pole bracket | 1 per AP |
| SPD | At the building entry / cabinet | Per local code |
For a 16-AP floor, use two splitters and one cascade link; check the PON optical budget before cascading.
Numbers to check
The design rules.
| Design rule | Value to confirm |
|---|---|
| PoF reach | 200 m per port |
| PoF power | 12 W per port |
| Wi-Fi 6 AP load | 10 – 15 W typical; check peak |
| APs per splitter | 8 (16 with cascade) |
| PoE limit | 100 m copper |
| Splitter budget | 8 × 12 W = 96 W; do not exceed the 120 W supply |

Outdoor Wireless Coverage: site questions.
If your question is not here, send the site details and we will answer with the calculation, not a brochure.
Ask an engineerCan PoF power a Wi-Fi 6 AP?
Yes if the AP draws under 12 W including peak radio load. The PoF ceiling ONU is itself a Wi-Fi 6 AX3000 AP, so the ONU and the AP are one device in that design.
How far can an outdoor AP be from the building?
Up to 200 m on PoF for a 12 W load. Beyond that, run fibre to a local cabinet with a PoE switch and power the AP locally, or use a point-to-point wireless backhaul.
Do I need a controller for roaming?
The PoF ceiling APs are managed by the gateway’s built-in AC or the OLT, with seamless roaming. If you use third-party APs, roaming depends on their controller or standard 802.11k/v/r support.
What about lightning?
The fibre is dielectric, so it does not bring a metallic path to the AP. The 48 V pair still needs surge protection at the building entry and a bonded mounting pole; follow local code.
Can I use PoF for a high-power outdoor AP?
Only if its peak draw stays under 12 W. Outdoor APs with heaters often exceed that; use a local PoE switch in a cabinet or a higher-power PoF design.
How many APs per PoF splitter?
Eight, or 16 with a second splitter on the cascade port. Keep the total DC load within the 120 W supply and check the optical budget after the cascade.
