Abstract
Various designs of pluggable variable optical attenuator (VOA) are disclosed. A pluggable VOA has an optical fiber adaptor connected to an internal VOA via different fiber optical interface configurations. At least a pair of ports is provided to accept optical fibers or external optical fiber ferrules for optical pluggability. The VOA is controlled electronically or manually. To facilitate a control of the VOA via a hosting system, an electronic device and/or interface is provided. External commands take the control of the VOA and set an attenuation level within a specification when the pluggable variable optical attenuator device is connected to a hosting system.
