Extender consists of a transmitter AF-201AV and a receiver FA-201AV .
The analog video input signal is digitized(10bit) pixel for pixel in the transmitter, sent digitally through the fiber cable, and converted back to analog video in the receiver.
The analog audio signals are digitized(20bit) in the transmitter, sent through the fiber cable, and converted back to analog audio in the receiver.
The AF-201AV transmitter are class 1 laser products.
AF-201AV provides a built-in color bars and embedded 2 channel audio signal(1KHz and 2KHz) test generator standard SMPTE-259M.
FA-201AV provides a built-in color bars and embedded 2 channel audio signal(1KHz and 2KHz) test generator .
