What is the HX-COX902MPOE used for?
It puts an Ethernet link onto existing coaxial cable. Buildings wired for analogue CCTV already have coax to every camera position; this converter lets an IP camera use that cable instead of pulling new Cat5/6 through finished walls.
The specification gives 0–500 m of transmission over Coaxial cable, twisted pair, RVV cable, at 90 Mbps. The pair works as a matched set — one unit at each end of the coax run — and the link speed is limited by the converter, not by the cable.
How far can the coax run?
This model is rated to 0–500 m. That is far beyond the 100 m copper Ethernet channel limit, which is the whole point: the distance budget is spent on the coax, and the Ethernet side stays short at both ends.
Coax attenuation rises with frequency and with cable age, and a run that worked with analogue video is not automatically clean for a modulated Ethernet signal. Keep the run on one continuous cable, avoid daisy-chained taps designed for analogue, and terminate properly at both ends.
How is it powered, and does it pass PoE?
Power input is Standard PoE or DC 44–57 V through a 5.5×2.1 mm jack, and the PoE output is 30 W (IEEE802.3af/at).
Where the PoE output is specified, the far-end device can be powered from the coax side, which is what allows a PoE camera to run on a single coax drop with no local supply.
The interface at the coax end is Q9 female; the network side is RJ45.
When is a converter the right answer, and when is it not?
It is the right answer on retrofit work where the cable already exists, where the run is long, or where the building fabric cannot be opened. It is the wrong answer for a new installation: new Cat6 is cheaper than two converters per run and has no power supply of its own to maintain.
Check two numbers before ordering: the run length against 0–500 m, and the camera bandwidth. A converter shares its rated throughput across everything on that link, so several cameras on one coax pair is a different calculation from one camera per pair.
How do the models in this family differ?
The family differs on distance, on throughput and on whether the far end receives PoE.

| HX-COX902B | 0–2000 m | 92 Mbps | — |
| HX-COX902M | 0–500 m | 94 Mbps | — |
FAQ
Does it work on any coax?
It is specified for the media listed above. The practical checks are continuity, characteristic impedance consistency and the condition of the connectors; a coax run that has been spliced several times for analogue taps is the usual reason a converter link will not come up.
Can I use one converter on its own?
No — the pair is the product. One unit modulates onto the coax and the other recovers Ethernet at the far end; a single unit has nothing to talk to.
What link speed do I actually get?
The published figure is 90 Mbps for this model, which is the throughput the pair sustains over the coax. Plan the camera bitrate against that number, not against the gigabit port on the switch.
Is it a replacement for a PoE extender?
No. A PoE extender repeats a PoE link over twisted pair; this converter changes the physical medium to coax. Which one applies depends entirely on what cable is already in the wall.
