AFBR-15x9Z analog Transmitter
The AFBR-15x9Z analog transmitter utilizes a 650 nm LED source in a housing designed to eciently couple into 1 mm
Polymer Optical Fiber (POF) or 200 µm Plastic-Clad Silica (PCS). Links up to 50 meters are supported with 1 mm POF.
Links up to 200 meters are supported with 200 µm PCS.
