One Coax Outlet. 2.5 Gbps.
Built-In PoE+.
KB-M3-03 — the only MoCA 2.5 adapter on the market with integrated PoE+ power delivery.
Mount a Wi-Fi access point on the ceiling, a security camera outside, or a VoIP phone anywhere in the building — with no outlet or power brick at the device, no PoE injector, and no electrician. The KB-M3-03 turns your existing coax into a multi-gigabit backbone and powers the device on the other end of its Ethernet cable with PoE+: 30W at the port, up to 25.5W at the device.
Data over coax, power over Ethernet, from one adapter.
Coax wiring runs through nearly every home and office. The KB-M3-03 connects at each end — one near your router, the other wherever you need connectivity — and delivers both a 2.5 Gbps Ethernet link and PoE+ power through that single Ethernet output. The adapter itself plugs into a wall outlet with its included power adapter, so the access point, camera or phone you connect needs no power supply of its own. No extra cable run, no compromise.
Why People Choose the KB-M3-03
First to market
The only adapter combining MoCA 2.5 speed with PoE+ power delivery in a single, easy-to-use kit.
Real, tested throughput
iperf-verified 2.5 Gbps performance, even with up to 50 dB of cable attenuation. Built on the MaxLinear MxL3710 + GPY211 PHY.
Power where you need it
PoE+ output: 30W at the port, up to 25.5W at the device — enough for Wi-Fi 6E/7 access points, IP cameras, and VoIP phones, with no outlet needed at the device.
True plug & play
No software, no drivers, no configuration. Plug in the coax, the power adapter and the Ethernet cable, and the link — plus PoE+ — is live.
Mesh & AP backhaul ready
A stable wired backhaul for mesh Wi-Fi systems and ceiling-mounted access points, without running new cable.
Backward compatible
Works alongside MoCA 1.1 / 2.0 / 2.5 gear, though overall network speed follows the slowest device.
Typical setup: a Wi-Fi access point, security camera, or VoIP phone connected through a single coax outlet and powered over its Ethernet cable — no separate power supply at the device.
Access points, cameras,
and hard-to-wire spots
Anywhere you need both a fast connection and power but have no outlet — a ceiling, an attic, an outdoor wall — the KB-M3-03 is the simplest way to get it done. It plugs in next to your coax outlet and powers the device over its Ethernet cable.
Common questions before you buy
"Will it power my access point?"
Yes — PoE+ (IEEE 802.3at): 30W at the port, up to 25.5W delivered to the device, enough for most Wi-Fi 6/7 access points, IP cameras, and VoIP phones.
"Is setup complicated?"
No — connect the coax, plug in the power adapter and attach the Ethernet cable. Data and PoE+ power are then live, with no configuration required for typical use.
"What if I'm not happy with it?"
30-day returns through Amazon, plus a 1-year warranty if anything goes wrong after that.
Ready to power and connect, without new wiring?
Get multi-gigabit speed over the coax you already have, plus built-in PoE+ for the device you connect.

Setup & Tutorial Videos
► Configure MoCA in D-Band High to eliminate DOCSIS 3.1 interference
Shift to D-band High (1350–1675 MHz) to avoid overlap with DOCSIS 3.1 modems/routers that reach up to 1218 MHz. Update every MoCA device to the same D-band High setting and LOF value for a solid, interference-free connection.
- Open the MoCA settings on each adapter via its web interface.
- Set the frequency band to D-band High (1350–1675 MHz).
- Apply the 1400 MHz LOF value on every MoCA device.
- Repeat for all adapters in the network.
- Restart each device to apply the new settings.
- Reconnect everything and confirm MoCA link lights are solid and performance is stable.
► Check firmware and link rate for stable performance
If issues arise, check the adapter's firmware version and link rate. The link rate reflects the stability of the MoCA connection — a healthy rate is typically around 3500 Mbps.
► Switch from static IP to DHCP for automated management
Prefer the adapter to pull its management IP via DHCP? This guide walks through enabling DHCP on the device for easier, more flexible network management.
► Enable MoCA traffic security across your network
The Security feature protects data on your MoCA network from unauthorized devices. Every MoCA device must support and enable it — MoCA 2.5 devices generally do, but older ones may not. Verify your device types before enabling to avoid connection failures.
