Application engineering
Start from the place. The product follows.
Each design begins with the device, the distance, the load and whether mains exists at the endpoint. That is what decides PoE, PoF, or fibre to a local cabinet.

Which path usually wins.
| Application | Typical distance | Typical load | Usual path | Watch-out |
|---|---|---|---|---|
| CCTV on poles | 100–300 m | 8–12 W fixed; 25–60 W PTZ | PoE within 100 m; PoF for 100–200 m | PTZ heater exceeds 12 W |
| Outdoor wireless | 100–200 m | 10–15 W | PoF ceiling ONU | Check peak radio load |
| Parking lot | 100–400 m | 8–40 W | Fibre to cabinet + PoE; PoF for isolated poles | LPR illuminator load |
| Perimeter | 200–1,000 m | 8–50 W | Fibre ring + local switch; PoF for low-power points | Surge and ring recovery |
| Bollard / access | 50–200 m | 5–20 W | PoF for reader/intercom; mains for motor | Motor is not a PoF load |
| Campus | 200 m–2 km | Mixed | PON backbone + building PoE + PoF edge | Optical budget per building |
| FTTH | 1–20 km | Per subscriber | OLT + 1:32/1:64 + ONT | Split ratio vs 3 dB margin |
| Industrial / tunnel | 500 m–several km | Mixed | Fibre ring + hardened PoE | Cabinet temperature |
| Hotel & hospitality | 20 m–200 m per floor | 10–15 W AP; room ONT | PON to room; PoF/PoE corridor | CATV/POTS and corridor power |
| Classroom & campus | 100 m–2 km | 10–15 W AP | PON to classroom + PoE/PoF edge | AP per room, not corridor only |
| AC + AP wireless | 20–100 m per AP | 10–30 W AP | PoE within 100 m; PoF 100–200 m | AP count and roaming |

Application FAQ
Application questions before the site visit.
If your question is not here, send the site details and we will answer with the calculation, not a brochure.
Ask an engineerHow do I know which application page applies to my site?
Start from the place and the device, not from the product. A camera on a pole, an AP above a ceiling, a reader at a gate and a room ONT are four different power problems. The eight pages cover the common place types; if your site is a mix, the design method is the same.
Can I use PoF for a camera that needs 30 W?
No. The PoF port is rated to 12 W. A 30 W PTZ camera with a heater needs a local PoE switch or a mains feed. PoF is for low-power endpoints: fixed cameras, APs, readers and sensors.
Is there a design for a hotel or a dormitory?
The campus and FTTH designs cover the room distribution, and the PoF page covers the corridor ceiling APs. For a hotel, the typical chain is a GPON OLT, 1:32 splitters, room ONTs with CATV/POTS and a PoF or PoE corridor AP group.
What if the site has both copper and no-mains endpoints?
Separate the power domains: a PoE switch for the copper group and a PoF splitter for the no-mains group. Both can uplink to the same OLT or core switch, but the budgets are calculated separately.
Do you provide the optical and power calculation with the design?
Yes. Each application page shows the path comparison and a bill of materials; the quotation adds the worst-case optical budget, the PoE/PoF load and the assumptions used.
How do I choose between PoE, PoF and fibre on a mixed site?
Use three inputs: distance from the nearest powered cabinet, load per endpoint and whether mains exists at the endpoint. Inside 100 m with mains, PoE is usually cheapest. From 100 to 200 m without mains and under 12 W per port, PoF fits. For clusters or loads above 12 W, run fibre to a local PoE switch.
Next step
Send the place, the device and the distance.
A rough sketch is enough. We will tell you which path fits, what the load budget is and which parts are missing from the drawing.
No obligation. The plan states its assumptions so your engineer can check it.
