 81-F

3G/HD/SD Optical SDI to HDMI Converter

Application Example

One useful application for BrightEye 81-F is shown below. In this case, an electrical signal from an  

HD router in a remote location (a distance of up to 20 km) is needed in another location. The electrical 

signal from the remote HD Router can be converted to optical by a BrightEye 46, then sent over 

optical cable to the other location where it is converted back to electrical by the BrightEye 81-F, which 

provides one HDMI and one electrical SDI output.
