PSG-001 Polarization State Generator

1310, 1550 nm; IL <0.5 dB; Switching Speed 100 µs; Polarization Rotation 45°, 90°; ER >18 dB; RL >55 dBLunas’ PSW-002 is a solid-state polarization switch that can quickly and repeatably rotate the state of polarization (SOP) of incoming light by a fixed angle, either 45° or 90°. Both single mode (SM) and polarization maintaining (PM) fiber pigtailed versions are available.With the PM option, the PSW-002 device functions as a TE to TM converter, switching the SOP between being aligned with the slow and fast axes of the PM fiber, or between the slow axis and 45° from the slow axis. With the SM option, the device simply rotates the polarization ellipse either 45° or 90°.The device can be used for polarization sensitive OCT, polarization sensitive OTDR or OFDR, PMD monitoring, polarization modulation, polarization detection, and polarization metrology. An optional driver board simplifies switch control by allowing the user to control the output SOP using TTL levels.Key Features:Switching Speed: 100 µs TypicalNo Moving PartsLow Insertion Loss (IL): <0.5 dBOperating Wavelength: 1550 ±30 nm or 1310± 30 nmPolarization Rotation: 45 ±0.5° or 90 ±0.5°Rotation Angle Temperature Dependence: -0.1, -0.2°/°CReturn Loss (RL): >55 dBSwitching Current: <130 mASwitching Voltage: 2.5 VLatching Current: ~80 mALatching Voltage: 1.5 to 2 VExtinction Ratio: >18 dB for PM ModelFiber Type: PM Panda, SMF-28 or CompatibleDimensions: 40 x 17.5 x 13.5 mm (Optical Head), 38 x 38 x 15 mm (Board)Applications: Polarization-diversified Detectors and Sensors; PMD Monitoring, Polarization Modulation; Polarization Detection; Polarization Metrology; Coherent Communication

The card can be configured to accept either a ±12 VDC power supply or an optional external 160 V power supply.As a polarization controller, the PCD-M02 can convert any input polarization state to any desired output polarization state. As a scrambler, it can randomize the output polarization state. This module offers the low insertion loss, low back reflection, and low activation loss needed for test and measurement applications, combined with the compact size needed for system integration or handheld devices.Key Features:Minimal Insertion Loss (IL): <0.05 dB Without Connectors, <0.6 dB With ConnectorsMinimal Activation Loss (AL): 0.01 dB, 0.05 dB Fast ResponseDigital and Analog ControlCompact SizeOperating Wavelength Range: 1260 to 1650 nm, 980 to 1310 nmPolarization Control Range: 3 or 4 Channels, 0 to 4π Each ChannelLow Polarization Dependent Loss (PDL): <0.05 dB Low Polarization Mode Dispersion (PMD): <0.05 ps Return Loss: >65 dBOptical Power Handling: 1,000 mWBoard Dimensions: 100 x 100 x 17.5 mmApplications: Polarization Control; Polarization Scrambling; PDL Measurement; PMD Compensation/Emulation; Fiber Sensor
