Text version of the page

SANTEC OPTICAL COMPONENTS Optical Wavelength Locker OWL-10 Wavelength Locker OWL Series Dimensions Typical Configuration The OWL -10 wavelength locker enables the wavelength of DWDM transmitters to be monitored and stabilized. Santec's unique single filter differential method is utilized to achieve the highest wavelength accuracy and reliability of any commercial wavelength locking device. The OWL-10 has become the industry standard and is indispensable in 50GHz and 100GHz DWDM systems. Features Unique differential method using high performance optical filter Passive (no moving parts, no power supply required) Suitable for any wavelength in the C & L bands Temperature insensitive @ 0~70°C (by thermal compensation) Wavelength accuracy < ± 0.01nm Hermetically sealed to ensure long term stability Small package (40 x 21 x 8 mm) Qualified to Telcordia GR-468 PM fiber option available Applications LD wavelength locking for DWDM transmitters. Wavelength monitoring in DWDM transmission systems. Wavelength management for DWDM wavelength router or OADM. Light source stabilization for optical information, sensing and other measurement applications. 6 5 4 3 2 1 6-ö0.45 28 34 40 4R3.0 4R0.5 2-ö2.3 21 15 9.5 2.54x5-127 2.54 10 5 ö4 ö6 1 1.6 7.9 9 2.5 • Electrical pin assign 1.
