... Transmitters incorporate a 660 nm LED. Receivers include a monolithic dc coupled, digital IC receiver with open collector Schottky output transistor. An internal pullup resistor is available for use in the HFBR-25X1/2/4 receivers. A shield has been integrated into the receiver IC to provide additional, localized noise immunity. Internal optics have been optimized for use with 1 mm diameter plastic optical fiber ...

... Optical flux, P (dBm Log P( W)/1000 W. 3. Because of the very high sensitivity of the HFBR-25X3, the digital output may switch in response to ambient light levels when a cable is not occupying the receiver optical port. The designer should take care to filter out signals from this source if they pose a hazard to the system. ...
