mVOA Variable Optical Attenuators

980-1650 nm; 3, 4 Channels; Polarization Control Range 0-4π Each Channel; IL <0.05, <0.6 dB; PDL <0.05 dB; PMD <0.05 ps; AL <0.01, <0.05 dB; RL >65 dBLunas’ PCD-M02 polarization controller module integrates an all-fiber dynamic polarization controller with a miniature piezo driver card, so that the SOP of the signal can be directly controlled either by a 0 to 5 V analog control signal or a 12-bit TTL digital control signal.The 3- or 4-channel polarization controller module features an on-board high voltage DC/DC converter, so no external high voltage power supply is required. 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
