coaxial ethernet adapter

These adapters use RJ-45 ports on the Ethernet side and F‑type coaxial connectors on the coax side. Listings frequently list the network connection as “Connection Type: RJ‑45 (Ethernet)” and refer to F connectors for the coax interface.

Reported speeds vary by model. Examples in the listings include up to 100 Mbps over coax, a DECA network described as a shared 200 Mb/s, and one listing showing a Maximum Wired Speed of 2500 Mbps. Check each product’s specs for its advertised throughput.

Most listings are sold as two‑unit packs or kits. Descriptions commonly state “Pack of two (2)” or “2 Pack,” and kits usually include two adapters plus any cables or power supplies.

Range varies by device and use case. Examples from the listings include a digital audio extender rated up to 328 ft and a related product listing a cable length of 60 ft. Always check the specific product’s range specification for the model you plan to use.

Common options include female‑to‑female F/coax RF couplers and RJ45 (Cat5e) keystone couplers or wall plates. One recessed wall plate listing specifically shows a female F connector paired with an RJ45 Cat5e coupler and notes use of in‑wall rated cable.

Many adapters use LED indicators: a light may flash during negotiation and then remain solid when the link is established. Setup notes also mention powering the units by USB or an external supply; in some listings the link becomes active within about a minute—refer to the product manual for exact LED meanings and expected timing.

Listings reference standard RJ‑45 Ethernet connections. Port counts vary by unit; several entries show a single RJ‑45 port while some devices or kits list two Ethernet ports. Verify the product page for the exact number of ports.

The listings describe using an adapter near a router to inject internet onto existing coax, then distributing that connection over coax (often through splitters) for whole‑home DVR or connected‑home setups. They also describe connecting a router Ethernet port into coax for network distribution across the home coax wiring.
