LASER DIODE
NX8562LB
1 550 nm CW LIGHT SOURCE
InGaAsP STRAINED MQW-DFB LASER DIODE MODULE
DESCRIPTION
The NX8562LB is a 1 550 nm laser diode with Polarization Maintain Fiber (PMF).
This device is designed as CW light source and ideal for transmission systems in which external modulators are
used.
FEATURES
• Output power
Pf = 20 mW MIN.
• Wavelength selectable for ITU-T standards
• Internal thermo-electric cooler and isolator
• Hermetically sealed 14-pin butterfly package
• Polarization maintain fiber pigtail
