Network equipment manufacturers and transceiver manufacturers know that variable attenuators are essential components of their test systems. They look for performance, user-friendliness, complete control of test parameters and advanced programming capability. EXFO’s FTBx-3500 Variable Attenuator combines innovative design techniques, high-quality components and meticulous calibration procedure. The power monitoring option allows the attenuator output power level to be set directly. When enabled, this function ensures power stability, even if the source power fluctuates. This option also simplifies test setups, eliminating the need for an external power meter. Flexible, fully programmable and built for both single-mode and multimode applications, the FTBx-3500 features an extremely rugged design allowing 24/7 operation for years without maintenance. The attenuating filter technology used in the FTBx-3500 makes it ideal for multimode BER and transceiver testing. Featuring integrated power monitoring, the FTBx-3500-BI allows you to precisely control the amount of power your receiver (Rx) under test detects, thereby enabling you to achieve proper BER measurements. The FTBx-3500-CI or FTBx-3500-DI enable similar characterization for multimode applications. When calibrating your system, you can choose between two offsets. The first is wavelength-independent and can be used to account for loss in the test setup, if applied to the attenuation or power setting. The second offset acts as a calibration factor, ensuring wavelength-specific correction levels and compensating for loss due to patch-cords and connectors.
