Cisco CAB-ASYNC-8 is an 8-port asynchronous serial cable manufactured by Cisco. It features a high-density 68-pin male connector to eight RJ45 connectors, supporting low-speed serial interfaces for data communication tasks.

This cable connects to compatible network interface modules such as WIC-2T or NM series cards with HD68 ports on select Cisco routers. Each port supports standard RS-232 signaling and operates independently for console access or terminal connections in rack-mounted configurations. This passive cable requires no power source.
