The EXFO FTBx-3500 Variable Attenuator is a precision optical attenuation module engineered for high-reliability testing in lab, production, and manufacturing environments. Designed to support both singlemode and multimode applications, this variable optical attenuator delivers exceptional performance, control, and programmability — ideal for transceiver testing, bit-error-rate (BER) validation, system verification, and automated test systems.

Features

• Fibre Compatibility: Singlemode and multimode variants.

• Attenuation Resolution: ~0.002 dB typical for precise control.

• Low Insertion Loss: Typical 1dB

• Fast Transition Speed: Quick response times for efficient test cycles.

• Robust Connectivity: High return loss and isolation ensure signal integrity across test configurations.
