JDSU WVL-2B1050412

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
• 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 (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.
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.
