Cosemi launches new line of active optical cables

Cosemi Technologies has introduced 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 power delivery 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.

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.

As with Cosemi’s other USB cables, the new DP alt mode cables feature a proprietary Cosemi optical engine, which combines the control and power of a copper cable with the high-speed data transfer of fibre optics.
