 The NI Ettus USRP X4x0 is compatible with most brands of SFP+ fiber adapters. In some cases, other equipment in the systems such as 1/10/100 Gigabit Ethernet switches are only compatible with specific brands of SFP+ adapters and cables. As a general rule, we recommend checking compatibility with the switches and network cards in your system before purchasing an adapter.
