Mechanically adjustable/dual wavelength (1210nm & 1550nm windows) 70-V Series variable optical attenuators (VOAs) have low backreflection <-55dB and meet attenuation requirements from 1 to 30dB. The 70-V Series is the ideal product for such applications as signal power reduction in point-to-point networks or signal power equalization between fibers in multifiber systems. The variable attenuator located 1 meter from the end of the cable). VOAs can also be custom configured to meet any specific pigtail length and connector requirements. Insertion loss of 1 to 30dB, operating temperature -40' to 85'C, resolution 0.1dB (1 to 10dB) and 0.5dB (10 to 30dB).
