The Exfo FTBx-3500 Series Variable Attenuators combine 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 singlemode and multimode applications, the FTBx-3500 Series features an extremely rugged design.
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 the user to precisely control the amount of power the user's receiver (Rx) under test detects, thereby enabling the user to achieve proper BER measurements. The FTBx-3500-CI or FTBx-3500-DI enable similar characterization for multimode applications.
When calibrating the user's system, the user 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 patchcords and connectors.
The Exfo FTBx-3500-BI-EI Variable Attenuator w/Power Monitoring may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
Functions
Attenuates optical signals across a wide wavelength range, typically 1250-1650nm. Provides precise control over attenuation levels with low insertion loss and high return loss. Simultaneously measures optical power levels via integrated power meter. Used for BER testing, margin analysis, and system characterization in fiber optic communication systems. Bidirectional capability supports testing in both transmission directions.
Platforms
Designed for integration within rackmount test platforms, specifically the LTB-8 chassis, this variable attenuator with integrated power monitoring operates on singlemode 9/125 µm fiber over 1250 to 1650 nm wavelength range. It connects via standard fiber optic interfaces and interfaces with test system controllers for precise attenuation and output power control, enabling automated transceiver testing and system verification in continuous 24/7 production environments. Compatible accessories include power meters (e.g., FTBx-1750) and MEMS optical switches (e.g., FTBx-9160) within the EXFO ecosystem, facilitating modular and scalable optical test configurations.
Accessories
FTBx platform chassis, optical patch cords (FC/APC, SC/APC, LC/APC), fiber optic cleaning kit. interfaces: Optical Input/Output (attenuator path), Optical Input (power meter), via interchangeable bulkheads; RJ45 (8P8C) Ethernet for remote control.
