FDE-002 Fixed Differential Group Delay

980-1650 nm; Total Phase Shift >8π; IL <0.1 dB; RL >65 dB; PDL <0.05 dB; Residual Amplitude Modulation ±0.01 dBLunas’ FPS-001 is an all-fiber device that shifts or modulates phase by up to 15π at frequencies from DC to 20 kHz. The advantage of the all-fiber construction is that insertion loss and back reflection are reduced to near zero.Key Features:Low Insertion Loss (IL): < 0.1 dBLow Residual Amplitude Modulation: ±0.01 dBNoTail™ Version AvailableOperating Wavelength: 1260 to 1650, 980 to 1310 nmReturn Loss (RL): >65 dBTotal Phase Shift (0 to 20 kHz): >8πHalf-wave Voltage (0 to 20 kHz): <20 VPolarization Dependent Loss (PDL): <0.05 dBMaximum Applied Voltage: 150 VDimensions: 35 x 14 x 14 mm (Pigtail), 74 x 14 x 14 mm (NoTail™)Applications: Precision Phase Tuning or Phase Modulation in Fiber Interferometers, Sensor Systems, Fiber Laser Systems or Fiber Resonators

1280-1620 nm; SOP Generation Accuracy ±1°; Azimuth & Ellipticity Angle Accuracy <0.25°; DOP Measurement Accuracy ±1%; PER Dynamic Range: >40 dB; PMD Measurement Range 0.001-10 ps, 0.001-400 ps; PDL Measurement Range 0-40 dBLunas’ PSGA-101 polarization measurement system is the most accurate product on the market for analyzing PMD, PDL and other polarization-related properties of light sources and optical materials.Based on Lunas’ patented magneto-optic polarization generation and analysis technology, the PSGA-101-A is specially designed for fiber optic applications and can effortlessly accomplish multiple functions, including polarization state generation (PSG), polarization state analysis (PSA), polarization extinction ratio (PER) measurement, polarization dependent loss (PDL) measurement, and polarization mode dispersion (PMD) measurement, as well as birefringence measurement in spun fiber.Another attractive feature of the PSGA-101 instrument is its large flip-top LCD graphic display design, allowing large viewing area on a compact, portable enclosure. Furthermore, a 2x20 character LCD is also included on the front panel for easy operation of the instrument for applications that do not require a graphic display.The instrument comes with an internal tunable laser for PDL and PMD measurement up to 10 ps. It can also control tunable lasers from third parties via a GPIB port for measurement of larger PMD values. The instrument also features a VGA port for use with an external LCD graphic display of the user’s choice.Key Features:Fixed Crystal Accuracy in a Swept SystemOperating Wavelength Range: 1440 to 1620 nm; 1280 to 1340 nmSOP Generation Accuracy: ±1° on Poincarè SphereAzimuth and Ellipticity Angle Accuracy: <0.25°DOP Measurement Accuracy: ±1%PER Dynamic Range: >40 dBPMD Measurement Range: 1 fs to 10 ps (Internal Laser), 1 fs to 400 ps (External Laser)PDL Measurement Range: 0 to 40 dBUSB Removable Data StorageGPIB Port for Control of Third Party LasersEthernet for Remote OperationMultiple Operation ModesFlip-top Graphic DisplayFront Panel Character LCD DisplayExternal LCD Monitor EnabledCompact and PortableApplications: Optical Component Characterization; Stress Evaluation of PM Connectors; PMD Measurement; PDL Measurement; Polarization State Generation (PSG); PER Measurement; PM Fiber Connector Key Alignment; SOP Measurement; Source DOP Measurement; Birefringence Measurement of Spun Fiber
