This BarnMini unit comes in two optical splitter versions; either as BarnMini-08-1:2 or BarnMini-08-1:4. It is a great supplement in smaller BarnMini systems, but can also be used in more advanced BarnOne configurations. As with any of our other BarnMini modules; the BarnMini-08 has rock solid mechanics and technology and it can work in harsh environments.
