    A new Fabry-Perot wavelength locker includes a thermally stable, etalon-based device, which is made in-house. It is used in wavelength monitoring or ITU-grid channel locking in DWDM systems, laser stabilization for tunable laser, optical power, and network monitoring. A built-in thermistor is used to calibrate out residue thermal effects.

    PRESS RELEASE

    Athermal 25G-/50G-FSR Fabre-Perot Wavelength Locker

    Optoplex’s Athermal Fabre-Perot Wavelength Locker is a thermally stable, etalon-based device that can be widely used in wavelength monitoring or ITU-grid channel locking in DWDM systems, laser stabilization for tunable laser, optical power and network monitoring. The wavelength locker has a wide capture range and excellent wavelength accuracy. A built-in thermistor can be used to calibrate out residue thermal effects when even higher wavelength accuracy is required or for a very narrow-FSR locker. The key optical component of the wavelength locker is an Etalon which is made in-house with Optoplex’s proven technology in thin-film optical coating and optical contact.

    Key Features and Benefits
    -Athermal design
    -C+L-band coverage by a single device
    -Extremely low temperature dependence
    -High wavelength accuracy
    -Periodical locking covers all channels
    -Built-in thermistor for better locking accuracy
    -Telcordia GR-468 & 1221 compliant

    Applications
    -Precision laser locking for DWDM and ultra DWDM transmitter
    -Wavelength monitoring
    -Laser stabilization for tunable laser module
    -DWDM channel frequency and optical power monitoring
