Fiber Optic Attenuators

Thorlabs has a wide variety of single mode (SM), polarization-maintaining (PM), or multimode (MM) fixed and variable optical attenuators (VOAs). We offer SM and PM electronic VOAs that provide control of the output power with FC/PC or FC/APC connectors. Our SM and PM manual VOAs are available unterminated or with FC/PC or FC/APC connectors. Our SM fixed optical attenuators are fiber connectors that can be attached to an FC/PC or FC/APC SM fiber patch cable. We also offer variable optical attenuators for MM fibers with FC/PC or SMA connectors and fixed optical attenuators for MM fibers with SMA connectors.
