Product description


The F85RN is a leading dual display fibre optic amplifier from Takex. It can simply be taught four separate teaching modes through the use of one set button. And with two large clear 4-digit, 7-segment LED displays and three raised buttons with positive click feedback, it makes mode setting even easier.


The F85RN is also equipped with an optical transmission type, mutual interference prevention function to suppress the interference between up to eight units.


The sensor comes with a QR code on the side of the amplifier to access a quick reference guide on your smartphone or tablet. This is useful when checking the manual or changing the settings while installing on site.
