First-Class Building Block for Assessing Signal Attenuation
High-quality components and meticulous calibration procedures make the FVA-3150 Variable Attenuator the instrument of choice for repeatable and accurate attenuation settings (up to 65 dB). The FVA-3150 meets system and component manufacturers’ need for component and system loss simulation, instrument calibration, power meter linearity measurement and spectral tuning. Its ultra-low insertion loss enables you to optimize the loss budget.
The FVA-3150 is configured for singlemode or multimode fibers. Use it as a stand-alone instrument or mounted on a 19-inch rack (optional).
Rugged and Reliable
Flexible, fully programmable and built for both singlemode and multimode applications, the FVA-3150 features a truly rugged design that uses only two moving parts—a rotating motor for the shutter and a linear motor for the filter—and state-of-the-art electronics.
The attenuator’s optomechanical assembly was tested at its highest operating temperature, at a very high relative humidity level, and with a continuous incident optical power of 23 dBm at 1550 nm—the equivalent of eight years of operation in typical bit-error-rate (BER) testing conditions. Results showed that an FVA-3150 can withstand 24/7 operation for years without requiring maintenance.
