Cosemi Technologies has launched a line of active optical cables (AOCs) that feature DisplayPort (DP) alt mode technology to allow USB-C-enabled computers and mobile devices to connect directly to a display or monitor.
The first cable in this new line will enable full DP 2.0 (the latest DP specification) while supporting USB 2.0 to provide legacy support for millions of USB devices already in the market. The second cable will support DP 1.4, USB 3.2 and USB 2.0 in one cable. In addition to output, both Cosemi cables provide up to 60W of USB-C power delivery (PD) as well as the ability to charge devices, thereby enabling a single port interconnect for video, data and charging for DP or USB-C devices.
The DP alt mode cables use a proprietary Cosemi optical engine, which combines the control and power of a copper cable with the high-speed data transfer of fibre optics. The cables can be up to 15m long with a bend radius of 5mm.
Alt mode is a functional extension of USB-C, which enables a USB connection to transmit non-USB signals, such as DP and Thunderbolt 3. In the case of DP alt mode, a USB-C-equipped computer can connect directly to a display or monitor with a USB-C port. Driving the need for this DP alt mode technology is the growing trend of viewing higher resolution digital content over mobile devices.
“DP alt mode has helped accelerate the growth of DP beyond PCs into mobile applications. Our new line of DP alt mode AOCs deliver simultaneous video, power and data over the USB Type-C connector,” said Adrian Collins, marketing director at Cosemi. “Users receive superior performance with a reliable plug-and-play experience – all of the best benefits of our hybrid AOCs packaged into a single cable.”

Cosemi is an active member of both USB-IF (the governing organization of USB-C) and VESA (the governing organization of DP) – and is involved with the enablement of these standards through the development of AOCs that are longer and slimmer than standard copper cables and are capable of delivering high speed data transmission for high-performance applications.
The new Cosemi USB-C DP alt mode cables are currently sampling to key customers with general availability in Q1 2021.
