Variable Optical Attenuator (VOA)
Variable Optical Attenuator(VOA) This variable optical attenuator features continuously manually adjustable attenuation from zero to 40dB, low insertion loss, high return loss (greater than 50dB) and fine adjustment resolution (less than 0.2dB). It is an all-fiber device and has two models working at 1310nm and 1550nm respectively. Features: - Low insertion loss - Large attenuation range - High resolution - Applications: - Optical communication systems - Fiber component manufacture and test - CATV systems Specifications: Ordering Information: VOA-M-a-c-da: Operating Wavelength, a=1310 for 1310nm, a=1315 for 1310 and 1550nm dual wavelengths, etc. C: Pigtail Type, c=3 for 3mm jacket pigtail, etc. D: Connector Type, d=FA for FC/APC, d=SU for SC/UPC, d=N for no connectors, etc. Available Options: Connector Type: FC/APC, SC/APC, FC/PC, SC/PC, Wavelength: 1310nm, & 1550nm
