Dynamic variable optical attenuator with dual directional tapping
An attenuator device includes a housing that forms a channel configured to receive an optical fiber. The optical fiber includes a first fused fiber tap for a first signal direction and a second fused fiber tap for a second signal direction. The attenuator device also includes (a) a first bend control region, in series with the channel and aligned with the first fused fiber tap; (b) a first bend-inducing object that moves to selectively contact the first fused fiber tap in the first bend control region to alter a bend radius at the first fused fiber tap; (c) a second bend control region, in series with the channel and aligned with the second fused fiber tap; and (d) a second bend-inducing object that moves to selectively contact the second fused fiber tap in the second bend control region to alter a bend radius at the second fused fiber tap.
