Details

Transmitter

The transmitter consists of a 650-nm LED, which is controlled by a fully integrated driver IC. The LED driver operates at 3.3V. It receives Low Voltage Differential Signaling (LVDS) electrical input, and converts it into a modulated current driving the LED. LED and driver IC are packaged in an optical subassembly. The optimized lens system of the optical subassembly couples the emitted optical power very efficiently into 1-mm core POF cable.

 

Receiver

The receiver utilizes a fully integrated single chip solution, which provides excellent immunity to EMI and fast transient dV/dt rejection. The receiver directly converts light to a digital LVDS output signal and operates at 3.3-V nominal supply. The integrated receiver is packaged in an optical subassembly, which couples optical power efficiently from POF to the receiving PIN. The receiver features an analog monitor output of the incoming optical signal. The monitor output provides an analog voltage proportional to the average optical input
