Connection with DPAX
Opticis DisplayPort Data Recovery Repeater, DPAX, is an active repeater for
DisplayPort video signal to increase video transmission.
With using DPAX, DPFX-250 can extend its total transmission length even longer.
DPAX can be connected any side of DPFX-250, however, to connect on TX side of
DPFX-250, customized copper cable has to be used.

DPAX can improve transmission length of DPFX-250 via optical fiber. It has been
confirmed that DisplayPort signal transmission length has improved up to 300m when
using DPFX-250 with DPAX under certain environment such as below configuration.
Each 200m and 300m of DisplayPort signal transmission has successfully tested
when using GTX960 as a display source and ASUS PA328Q as a display.
