Copper Transceiver Module Sonnet AVB-TB 40000 Mbit/s RJ-45

The Sonnet AVB-TB Copper Transceiver Module is an AVB-capable Thunderbolt Gigabit Ethernet adapter module with an RJ-45 interface and a compact black housing. It provides a hardware endpoint for Audio Video Bridging (AVB) networks and is designed to connect Macs with Thunderbolt ports to AVB devices such as the Avid Pro Tools | Carbon audio interface. The module supports high-speed copper Ethernet connections suitable for professional audio and video workflows where synchronized, low-latency data transport is required.

Advantages

The transceiver offers AVB compliance for synchronized audio/video stream transport and enables a Thunderbolt-equipped Mac to act as an AVB endpoint. Its RJ-45 interface and support for high data rates provide stable copper connectivity for audio interfaces, mixers, speaker processors, stage boxes and similar networked devices. Basic driver support and configuration are handled by macOS, reducing setup complexity on Mac systems.

Key specifications

How to use

Insert the Sonnet AVB-TB module into the compatible Thunderbolt adapter or enclosure according to the manufacturer’s instructions and connect it to an RJ-45 copper Ethernet cable. Attach the Thunderbolt connection to your Mac and configure the network connection in macOS Network preferences. For AVB routing and clocking, open the Audio MIDI Setup application and any device-specific control software to assign AVB endpoints and set stream priorities.

Recommendations

Use shielded, high-quality Cat6a or better copper cabling for reliable high-speed AVB transport and to minimize interference. When integrating with Pro Tools | Carbon or other professional audio devices, follow the device manufacturer’s AVB setup guidelines and synchronize clocking between endpoints for lowest latency and stable operation.
