| 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 Compliance 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. * Telcordia 1221 NORTH AMERICA: 800 498-JDSU (5378) WORLDWIDE: +800 5378-JDSU WEBSITE: www.jdsu.com BROADBAND (FABRY-PEROT ) WAVELENGTH LOCKER 2 Theoretical Frequency Response: 50 GHz Etalon Photodiode (dB) 2.000 Diode Photocurrent (dB) 0.000 -2.000 -4.000 -6.000 -8.000 -10.000 38.5 Reference Photodiode (dB) 39.0 39.5 ITU Channel (GHz) 40.0 40.5 Optical Schematic Input Fiber Etalon Out Splitter Etalon PD2 Monitor Out PD1 BROADBAND (FABRY-PEROT ) WAVELENGTH LOCKER 3 Dimensions Diagram 8.5 mm 40.0 mm (Specifications in mm unless otherwise noted.) 21.0 mm 15.0 mm 18.0 mm 34.0 mm 18.0 mm Minimum Pin 6 Pin 1 O = 0.45 mm 5.0 mm 2.54 mm 5.0 mm 10.0 mm 2.54 mm x 5 8.5 mm Pinout Pin 1 2 3 4 5 6 Description Monitor PD1 anode (+) Etalon PD2 anode (+) PD1, PD2 cathode (-) Temperature sensor supply voltage Temperature sensor monitor Temperature sensor ground BROADBAND (FABRY-PEROT ) WAVELENGTH LOCKER 4 Specifications Parameter Wavelength range Center wavelength Center channel accuracy over temperature, polarization, and EOL1 Polarization dependent channel accuracy (included in total center channel accuracy) Acquisition range (capture range) from nominal ITU center frequency Locking slope at ITU point Optical operation power range (Pin) ~ input to module Optical return loss3 Optical input power for damage Photodetector calibration offset Photocurrent Responsivity of reference (PD1) Responsivity of etalon (PD2) Photodetector dark current Temperature sensor supply voltage at 130 A Temperature sensor monitor Package dimensions (W x H x D) Electrical pin spacing (center to center) Fiber type Operating temperature Storage temperature Humidity (noncondensing) 50 GHz Free Spectral Range 1520 to 1620 nm ITU grid (standard) or as specified 2.5 GHz2 0.8 GHz -30 to 12 GHz 80 dB/nm -25 to 7 dBm 50 dB 10 mW (CW) 2.5 dB 0.16 to 0.32 A/W 0.16 to 0.40 A/W 0.3 nA at 5 VR, 25C 0.5 nA at 5 VR, 25C 5 to 30 V 10 mV/C 40 x 8.5 x 21 mm 2.54 mm SMF-28 0 to 70C -40 to 85C 0 to 85% RH Maximum Maximum Typical Typical Typical Minimum Minimum Maximum Typical Maximum Typical Note: Data for temperature sensor reported at three temperatures at one wavelength (ITU 40).
