PDLE-101 PDL Emulator

DGD Range 0-200, 0-44 ps; DGD Resolution 0.2 ps; Single Band C, L, O, Dual Band CL; Max. IL 3.5 dB; Max. PDL 0.3 dB; RL >50 dB Polarization mode dispersion (PMD) can seriously degrade the quality of high-speed fiber-optic data transmission. High-speed transceivers must meet stringent standards for PMD tolerance. General Photonics’ DGD-1000 PMD Source/Emulator accurately and repeatably generates both high and low values of differential group delay (DGD) or first-order PMD. Both the DGD and PDL are very stable over time and wavelength within the performance band. The DGD-1000 PMD source/emulator is available in different versions to accommodate the need for different wavelengths and DGD ranges. Key Features: Generates Differential Group Delay DGD up to 400 ps DGD Range: 0 to 200 ps, 0 to 400 ps DGD Resolution: 0.2 ps DGD Change Rate: Up to 64 ps/s Wavelength Range Single Band: C Band, L Band or O Band Wavelength Range Dual Band: CL Bands Insertion Loss (IL): ≤3.5 dB Very Low Insertion Loss (IL) Variation Over DGD Range: 0.1 dB typ.

EP series laser diodes are available in a variety of industry standard and custom package types, as well as with wavelengths ranging from 657 to 2350 nm, suitable for sensing a broad range of chemical elements and substances: Calcium (Ca): 657 nm Oxygen (O2): 760 nm Rubidium (Rb): 780 nm Ytterbium (Yb): 1064 nm Hydrogen Fluoride (HF): 1278 nm Moisture (H2O): 1342 nm, 1392.5 nm, 1854 nm Ammonia (NH3), Acetylene (C2H2): 1512 nm Carbon Dioxide(CO2), Carbon Monoxide (CO), Hydrogen Sulfide (H2S): 1578 nm Methane (CH4): 1654 nm Hydrocarbon Compounds like Propane or Butane (CxHx): 1692 nm Hydrochloric Acid (HCl): 1742 nm Carbon Dioxide(CO2): 2004 nm, 2051 nm, 2051 nm High-power Nitrous Oxide (N2O): 2108 nm Carbon Monoxide (CO): 2327 nm Eblana can also realize DM laser diodes for any custom wavelength requirements with a proven track record of success – please contact the AMS Technologies’ laser diode experts who are committed to ensuring that our customers realize the perfect gas sensing solution to meet their technical and commercial needs – every time. Laser-based gas sensing applications require excellent tuning characteristics. Eblana’s discrete mode lasers feature mode-hop free tuning over a minimum of 2 nm. Utilizing a standard Fabry-Perot ridge waveguide process to ensure high reliability and consistency, Eblana’s discrete mode (DM) technology achieves excellent side mode suppression ratio (SMSR) and a narrow linewidth below 2 MHz. Wavelength-selective features are etched using surface-level lithography to create single mode (SM) lasers, and a multiple quantum-well epitaxial structure is grown by MOCVD or MBE. Compared with traditional DFB approaches, Eblana’s discrete mode technology is regrowth-free and the wavelength selection material-agnostic. Key Features: Excellent Spectral Purity Most Devices Tunable Over Multiple Absorption Lines Mode-hop-free Performance Threshold Current: 12 mA to 35 mA Slope Efficiency: 0.04 W/A to 0.21 W/A Output Power: 2 mW to 14 mW Tuning Coefficient: 0.003 nm/mA to 0.02 nm/mA Side Mode Suppression Ratio (SMSR): 40 dB Operating Temperature Range: -20 to +65 °C Package Types: 14-pin Butterfly, DX-1 Custom Package, TO-39 Applications: Trace Gas Sensing; Environmental Monitoring; High-sensitivity Detection; HF Measurement in Harsh Environments; High-temperature H2O Sensing; Wavelength Modulation Spectroscopy; Cavity Ringdown Spectroscopy ;Telecom; Fiber Coupling
