Looking for Patch Cables, Cable or Mini-Com ?

How do I run a USB cable over 40ft. in a plenum air space?

USB specifications limit connections to a maximum run of only around 15ft. This can make placement of USB devices difficult, especially when longer runs are required and you need to meet fire code requirements. There are several ways to acomplish running extended length USB cables in this environment, one of them is a product from Covid. Covid USB Extender Cable eliminates the USB length constraint allowing for extended USB connections. This extender does not require external power. Three extenders can be daisey chained for lengths up to 147 ft. Click here for the web page:
