The BarnOne series

The BarnOne series of signal transport frames provide a 32 x 32 built-in routing system with a combination of BNC and SFP I/O ports to satisfy any application. Several combinations of SFP-ports, BNCs and multiplexer are available.


Designed to be the most flexible, rack-space saving and affordable infrastructure platform in the audio, video and communication businesses. Highly compact and equipped with an up to 32×32 cross-point router. Barnfind offer a number of configurations to combine BNC, SFP and CWDM fiber optical multiplexing.

This BarnOne frame accept SFPs following the MSA standard – this includes optical, SDI copper, HDMI and RJ-45 Ethernet style SFP modules

The BTF1-10-AA includes all the features of the BarnOne frame series. Adding 8+8 balanced analog line level audio, a 264×264 channel audio matrix and 4+4 MADI interfaces. These are connected to the main 32 x 32 matrix of the BarnOne frame.

Ideal for optical signal transmission, remote stage box application and small studio style productions.
