Variable Attenuators
The OFR Variable Attenuator consists of the Fiber-to-Fiber Coupling System plus appropriate Polarizer and Retarder Modules.

Both Polarization Dependent and Independent Variable Attenuators are possible. In all FiberBench Coupling Systems using OFR PM FiberCables, both the fast axis and the FC receptacle keyway are vertical. Both the plane of polarization and the fiber stress rods are horizontal. A major feature of OFR FiberBench Coupling Systems is stability. Transmittance remains constant after temperature change, shock and vibration far greater than experienced in typical laboratory use.

Variable Attenuators
High Power SM Variable Fiber Attenuator High power model that provides 0 - 40dB attenuation. Polarization independent.	VA-FFB-S-λ--X Includes: FiberBench x2 PAF-X Disconnectable FiberPort x2 PBB Calcite Walk-Off Polarizers x1 RZB-1/2-λ Rotating 1/2 Wave Retarder x2 1m SM fiber, FC connector on one end OFR Alignment VA-FFB-S-λ--Y Same as above but with permanent pigtails input/output * Distal fiber ends can be connectorized please inquire.
High Power PM Variable Fiber Attenuator High power model that provides 0 - 40dB attenuation. Polarization dependent. The attenuator is initially aligned such that linear polarized light enters and propogates through the input retarder and calcite walk-off polarizer with zero displacement and zero attenuation.	VA-FFB-P-λ--X Includes: FiberBench x2 PAF-X Disconnectable FiberPort x1 RZB-1/2-λ Rotating 1/2 Wave Retarder x1 PBB Calcite Walk-Off Polarizer x2 1m PM input fiber, FC connector on one end OFR Alignment VA-FFB-P-λ--Y Same as above but with permanent pigtails input/output * Distal fiber ends can be connectorized please inquire.
High Power SM Variable Fiber Attenuator High power model that provides 0 - 40dB attenuation. Polarization independent. Attenuation is caused by the lateral misalignment introduced by tilting parallel plate.	VAT-FFB-S-λ--X Includes: FiberBench x2 PAF-X Disconnectable FiberPort x1 HW-XY-λ-T Tweaker Plate x2 1m SM input fiber, FC connector on one end OFR Alignment VAT-FFB-S-λ -Y Same as above but with permanent pigtails input/output * Distal fiber ends can be connectorized please inquire.
