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 dB General Photonics’ 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 Connectors Minimal Activation Loss (AL): 0.01 dB, 0.05 dB Fast Response Digital and Analog Control Compact Size Operating Wavelength Range: 1260 to 1650 nm, 980 to 1310 nm Polarization Control Range: 3 or 4 Channels, 0 to 4π Each Channel Low Polarization Dependent Loss (PDL): <0.05 dB Low Polarization Mode Dispersion (PMD): <0.05 ps Return Loss: >65 dB Optical Power Handling: 1,000 mW Board Dimensions: 100 x 100 x 17.5 mm Applications: Polarization Control; Polarization Scrambling; PDL Measurement; PMD Compensation/Emulation; Fiber Sensor

MEMS-based, Pigtail Style, Broadband; Single/Dual Types; Fiber Type Single Mode; 1240 to 1640 nm; Attenuation up to 45 dB Sercalo Technology’s VP series of MEMS-based, broadband variable optical attenuators (VOAs) achieves very low insertion loss and optimized polarization dependent loss characteristics. The VP series of variable attenuators allows the continuous adjustment of the attenuation with a 0 to 5 V control voltage. The highly reliable attenuation mechanism is based on a micromechanical shutter – moving an obstructing element into the optical beam between two single mode fibers – and features below 2 ms response time and only 0.5 dB insertion loss. The position of the obstructing element can be adjusted by an integrated electrostatic actuator, resulting in a fast and hysteresis free response. The low insertion loss and the fast response time make the VP series of VOAs ideal components for active power tuning in WDM networks. Their miniature package withstands rugged environments and is well suited for direct mounting on printed circuit boards Key Features: Reliable Low Insertion Loss (0.4 dB) Fast Response Time (2 ms) Low PDL Miniature Size Non-latching Remote Attenuation Control EDFA Control Applications: Power Management in DWDM Transceivers; Remote Attenuation Control; EDFA Control
