The cable test system comprises a single Cable Test System (CTS) device, multiple Cable Connector Box (CCB) devices and the accompanying Cable Test Application software. The diagram above depicts an abstract representation of all components involved in a cable test setup. On the left side, among the multiple FireSpy Engines shown, two are connected to CCBs. In the middle one can see that a CCB contains several PHY chips to form an active network switch that regenerates the signals close to the extension cables. Each extension cable is fed into a LEMO socket on the front panel of the CCB. The cable under test is connected in-between two CCBs using adapter cables to mate the connectors.
