Product Overview

The C2G C2G54278 1-Port USB-C Extender Transmitter to Receiver Kit extends USB-C data signals up to 33 feet using a CM-rated link cable, designed for conference rooms, huddle spaces, and classrooms where USB peripherals need to be placed beyond the native 16.4-foot USB cable limit. Leveraging USB 3.2 Gen 1 at 5 Gbps, this USB-C extender supports up to 30 connected USB devices and requires no software or drivers. The transmitter is bus-powered with an optional 5V DC input for supplemental power when needed.

Product Description

The C2G54278 kit includes a transmitter unit, receiver unit, and a 33ft (10m) CM-rated ARJ45 link cable. Each unit presents a single USB 3.2 Type-C port. The transmitter connects to the host computer or USB-C source, and the receiver connects to the USB-C peripheral at the remote end. The CM-rated link cable is suited for surface runs, cable trays, and conduit installations in commercial AV environments.

Note: The USB-C port on this extender is for data only at 5 Gbps DisplayPort Alt Mode video is not supported. This kit is the standard cable-rated counterpart to the C2G54279 (plenum-rated). For above-ceiling or in-wall runs requiring NEC plenum compliance, specify the C2G54279 instead. Both units are CE marked and conform to RoHS 2.

Frequently Asked Questions

What is the difference between C2G54278 and C2G54279?

The C2G54278 includes a CM-rated ARJ45 link cable for surface runs, cable trays, and conduit. The C2G54279 includes a plenum-rated (CMP) cable for above-ceiling and in-wall runs where NEC plenum compliance is required. Choose based on your installation environment and local building code.

Does this extender support USB-C video?

No. The USB-C port on each unit is for data only at 5 Gbps. DisplayPort Alt Mode and USB-C video output are not supported. A separate HDMI or DisplayPort adapter is needed for video extension.

Can I use this with a USB-A host?

A USB-A to USB-C adapter would be required at the host end, as both transmitter and receiver have USB-C ports. Adapters are not included.

How many devices can I connect through this extender?

Up to 30 USB devices including hubs. Each hub in the chain counts toward this total.

Is a power supply required?
