The DS1861 is a laser-driver control IC designed to

reduce the production cost of fiber optics circuits by

eliminating multiple temperature tests. It works with

nearly all laser-driver ICs to provide automatic power

control (APC) and automatic extinction ratio control

(AERC), which improves the performance of the system

over temperature and aging. It also has built-in monitor-

ing capability to provide early fault detection, which can

be configured to latch the IC into a shutdown condition.

Settings programmed into the DS1861 are stored in

password-protected EEPROM memory, which write-

protects calibration data. Programming is accom-

plished through an I

also be used to read diagnostic information.
