1. General
SLT5415 series are 1.5µm InGaAsP/InP MQW DFB laser diode modules designed for a CW optical
source of WDM (Wavelength Division Multiplexing) application used with an external modulator.
A laser diode chip is mounted on a 14 pin butterfly package integrated with an optical isolator, an
InGaAs monitor PD, a thermo-electric cooler, and a single mode polarization maintaining (PM) fiber
pigtail.
