COMMUNICATIONS COMPONENTS  
Broadband (Fabry-Perot) Wavelength Locker  
Key Features  
• Extremely low temperature dependence  
• High accuracy  
• Periodic locking covers all channels (one part number for  
any channel to reduce inventory)  
• Temperature sensor included for better locking accuracy, if  
necessary  
• Operation over C and L bands  
Applications  
The broadband (Fabry-Perot) wavelength locker is a thermally stable, air-gapped,  
etalon-based device that can be used to stabilize laser sources for high-density  
WDM applications and tunable lasers. Our 50 GHz, free spectral range (FSR)  
designs are industry-standard products.  
• Precise laser locking for DWDM  
and ultra DWDM transmitter  
• Wavelength monitoring  
• Laser stabilization for tunable laser  
module  
• DWDM channel frequency and  
optical power monitoring  
The broadband wavelength locker has a wide capture range and excellent  
wavelength accuracy. The temperature sensor, included with every locker, can be  
used to calibrate out thermal effects when even higher wavelength accuracy is  
required or when using a very narrow FSR locker.
