Features
Optical transmitter and receiver for maximum datarate 10 Mbaud (half duplex burst mode)
Transmitter: LED with 650 nm for working in low attenuation range of PMMA fiber
Receiver: Photodiode with preamp, digitizer with DC elimination circuit (tracked decision
threshold), Sleep - and Wake-up-Function, output stage (electrical output driver)
Built in transmitter and receiver gate for half duplex mode (mutual blocking of transmitter and
receiver)
Operation at 5V or 8V-11V power supply voltage
Built in pulse width detection for indicating Sync, Alarm and continuous light on (integrated time
basis to differentiate and evaluate Sync, Alarm and Continuous Light
conditions Alarm output)
Diagnose function for photocurrent
Mechanical assembly: 6 Pin CAI package for easy coupling of POF (plastic optical fiber) with insert
2. Basic Specification
2.1 Absolute maximum ratings
Note:
Usage of the device out of the maximum ranges given in this chapter may damage the
