PoF Switch & PoF ONU
A Power-over-Fiber access set: an optical gateway, an 8-output PoF power splitter, hybrid PoF cable and a ceiling Wi-Fi 6 ONU. Each output delivers up to 12 W to 200 m, so ceiling APs and cameras run without a local mains socket.

PoF here means Power over Fiber in the practical sense used on this site: a hybrid cable that carries one optical fibre and copper conductors in the same jacket. The fibre carries the data; the copper carries 48 V DC. One hybrid cable replaces a fibre drop plus a local mains spur, so a ceiling AP, a camera on a pole or an access-control reader can be installed where there is no socket.
The set is built around an 8-output PoF power splitter. It takes 48 V DC from a 120 W adapter, splits the optical signal 1×9 (eight outputs plus one cascade port) and delivers up to 12 W per output to 200 m. The splitter is a 1×9 PLC with ≤16.5 dB insertion loss on each output and ≤2.3 dB on the cascade port, working from 1260 to 1650 nm with SC/UPC or SC/APC connectors. Power and data leave on the same hybrid cable; the ceiling ONU separates them again.
The ceiling ONU is a Wi-Fi 6 AX3000 access point with one XPON PoF input, one GE port and five internal antennas. It is managed by the optical gateway (1 GPON + 2 GE + 1 10GE SFP+ with a built-in software AC) and supports zero-touch provisioning and seamless roaming. For larger floors, cascade a second splitter from the cascade port; each splitter adds its insertion loss to the optical budget, so check the PON budget before chaining more than two.
Configuration table
The numbers that decide the fit.
Values are from the model datasheet. Where a value is model-dependent, the table says so instead of guessing.
| Component | Ports | Power / optics | Role |
|---|---|---|---|
| Optical gateway | 1× GPON + 2× GE + 1× 10GE SFP+ | AC input, built-in software AC | PON headend and PoF source |
| PoF power splitter | 1 input / 8 outputs + 1 cascade | 48 V DC in/out, 120 W supply, ≤12 W per port | Splits optical signal and DC power |
| PoF ceiling ONU | 1× XPON PoF + 1× GE | Fed over the hybrid cable; Wi-Fi 6 AX3000 | Ceiling Wi-Fi access |
| Hybrid PoF cable | 1 fibre + copper | G.657A2, 3 / 20 / 50 m, SC/UPC | Data + power to the ceiling |
The 12 W per port is the splitter rating. The actual load must include the ONU, the radio and cable loss; leave at least 20% headroom.
Engineering features
What changes on site.
No mains at the ceiling
The AP gets 48 V DC over the same cable that carries the PON signal. No local socket, no electrician visit, no extra surge path at the ceiling.
200 m, not 100 m
The hybrid link reaches 200 m per port, twice the 100 m copper Ethernet limit. That covers a long corridor, a warehouse bay or a pole outside the building.
Wi-Fi 6 at the edge
AX3000 dual-band radio with five internal antennas, zero-touch provisioning and seamless roaming across ceiling units.
Isolated power path
The fibre is dielectric; the power pair is separate from the data path. The design removes the copper Ethernet run that normally brings surge into the ceiling.
Eight ports per splitter
One splitter feeds eight APs. A second splitter on the cascade port takes the count to 16; the cascade adds ≤2.3 dB to the optical budget.
Managed as one PON
The gateway’s built-in AC and the OLT manage the APs as one network: SSIDs, VLANs, firmware and roaming policy in one place.
Selection guide
Which configuration fits which site.
Start from the site, not from the model. The table is a starting point; the final check is the optical and power budget.
| Layout | Splitters | APs | Note |
|---|---|---|---|
| Small floor / 8 rooms | 1 | Up to 8 | One 120 W adapter; check total load ≤96 W |
| Two floors / 16 rooms | 2 | Up to 16 | Cascade the second splitter; add 2.3 dB optical loss |
| Corridor + outdoor pole | 1 | 4–6 | Keep 20% power headroom for cable and radio peak |
| Mixed PoF + PoE | 1 splitter + PoE switch | 8 PoF APs + PoE cameras | Separate power domains; do not parallel the 48 V rails |
Do not exceed eight powered outputs on one splitter. For loads above 12 W per port, use a local PoE injector or a higher-power PoF design.
Integration
Where it sits in the chain.
The PoF chain starts at the optical gateway, passes through the power splitter and ends at the ceiling ONU. The optical budget and the 48 V DC budget are calculated together.
- One bill of materials for the whole chain

View specificationsProduct FAQ
PoF Switch & PoF ONU: questions before the order.
If your question is not here, send the site details and we will answer with the calculation, not a brochure.
Ask an engineerIs PoF the same as PoE over fibre?
No. PoE sends DC over copper Ethernet pairs. PoF as used here sends DC over the copper conductors in a hybrid fibre cable, alongside the optical fibre. It is not a standard IEEE PoE mode and does not run over a standard patch cord.
How much power is available at 200 m?
The splitter output is rated at up to 12 W per port with a 120 W supply. Voltage drop in the copper pair reduces the power available at the far end; the actual figure depends on cable length and load. Calculate with the cable resistance and leave at least 20% headroom.
Can I power a PTZ camera over PoF?
Only if its steady and peak draw stay within the 12 W port budget, including heater and pan/tilt peaks. Most PTZ cameras with heaters exceed that; use a local mains feed or a higher-power PoF design for those.
What happens if the copper pair shorts?
The splitter’s output protection limits the fault current. Use a fused or current-limited 48 V supply and protect the outdoor cable at the entry point. The optical path is unaffected by the electrical fault.
How many splitters can I cascade?
The splitter has one cascade port with ≤2.3 dB insertion loss. Cascading two splitters is common for 16 APs; each additional stage adds loss and reduces the optical margin, so calculate the PON budget before adding a third.
Does the ceiling ONU need a separate power adapter?
No in the PoF configuration; it is powered over the hybrid cable. A DC 12 V adapter is available as an option for bench testing or a non-PoF site.
Is the system compatible with a third-party OLT?
The ONU is XPON and can register on a compatible GPON/EPON OLT, but the zero-touch AC and roaming features are tied to the gateway/OLT ecosystem. Confirm the OLT and firmware before mixing vendors.
