LASER DIODE
NX8563LB Series
CW LIGHT SOURCE
InGaAsP STRAINED MQW-DFB LASER DIODE MODULE
FOR D-WDM APPLICATIONS
DESCRIPTION
The NX8563LB Series is a 1 550 nm laser diode with Polarization Maintain Fiber (PMF).
This device is designed as CW light source and ideal for D-WDM transmission systems in which external
modulators are used.
FEATURES
• Output power
Pf = 10 mW MIN.
• Wavelength availability
λp = 1 540 to 1 560 nm, ITU standard based
• Internal thermo-electric cooler and isolator
• Hermetically sealed 14-pin butterfly package
• Polarization maintain fiber pigtail
