MEMS VOA动态可调光衰减器 VOA光衰减器

  动态可调光衰减器 MEMS VOA光衰减器   Product Description L-series VOA is a VOA product family using the MEMS chip with a movable mirror on the silicon. The mirrorattenuates the laser light power by coupling the input beam onto the output fiber. The applied voltageto the device controls the mirr or tilt angle, thus the desired attenuation amount. 微机电可调光衰减器 MEMS VOA 是一种新型的低成本、小体积的电磁驱动微机电系统可调 光衰减器 , 可用于密集波分复用系统中各信道的动 态增平衡。 Features Applications   Low insertion loss - Channel on/off switch - Low polarization dependent loss - Channel equalization - Miniature design - Receiver protection - Low power consumption - Power equalization in OADM/ROADM - High shock & vibration immunity - Power equalization in VMUX - Telcordia 1209 & 1221 compliant - EDFA GAIN-TILT control Specifitions Parameter Unit Specification Configuration   Bright Dark Wavelength Range nm C band 1525 - 1570 L band 1570 - 1610 Attenuation Range dB 25/40 25/40 Repeatability dB 0.1 0.1 Atteruation Slop dB/ V 20 20 nsertion Loss dB 1 1 Return Loss dB 45 45 Polarization Dependent Loss 0dB 0.2 0.2 0dB ~ 10dB 0.4 0.4 10dB ~ 20dB 0.8 0.8       Flat-ness     Broad Application       band 0dB 0.2 0.2 0-10dB 1.0 1.0 10-20dB 2.0 2.0   Narrow Application 0dB 0.25 0.25 0-10dB 0.5 0.5 10-20dB 0.5 0.5 Wear-out Cycle 10 10 Response Time ms 5 5 Total Optical Power mW 500 500 Dimension mm 16×Φ5.4 (L×D) Fiber Type   Corning SMF-28(9/125μm)   Fiber Marking   Input port: Red   Output port: Clear Operating Temperature ℃ -5~70 Storage Temperature ℃ -40~85 Power Consumption mW 10 L Package Attenuation Type Wavelength Range Attenuation Range Drive Voltage Ripple Connector Type   1 TO46 B Bright C 1525-1570nm 25 25dB min L 6.5V N Narrow band 1 FC/UPC     D Dark L 1570-1610nm 30 30dB min H 15V B Broad band 2 FC/APC       S 850nm 40 40dB min X Customized  X Customized 3 SC/APC       H 1060 X Customized     4 LC/UPC       D 1310&1550nm       5 None X CustomizEd 微机械可调光衰减器（MEMS VOA）是采用静电驱动微反镜方案制作的可调光衰减器器件。本产品质量可靠、性能稳定，体积小。 产品通过Telcordia GR-1221-CORE试验，符合RoHS要求
