Laser diode driver of an optical transmitter circuit for
SDH (STM4)
Functional Description
The F0510203B is a high performance GaAs integrated laser diode driver for use in an
optical transmitter circuit up to 1.5 Gbps NRZ data rate. The F0510203B typically specifies
rise time and fall time of 100 psec (20% - 80%). It features single -5 V supply operation, 1 to
50 mA presettable bias current and up to 40 mA modulation current.
