FTBx 3500 EXFO Variable Light Attenuator

Fully programmable solution supporting remote control capabilities

Network equipment manufacturers and transceiver manufacturers know that variable attenuators are an essential part of their systems. To do so, they need high-performance, user-friendly solutions with complete control of test parameters and advanced programming capabilities. EXFO's FTBx-3500 variable attenuator combines innovative design techniques, high-quality components and a meticulous calibration process.

VOA with Full Remote Control UI Capabilities

Especially suited for bit-error-rate (BER) testing and system verification, the FTBx-3500 is a variable optical attenuator (VOA) with a fully remote-controllable user interface (UI) and is compatible with EXFO Multilink. It is also capable of providing a VOA for desktop devices, which can be controlled remotely or using a touch screen.

Option: Automatic Power Monitoring

The power monitoring option allows the output power level of the attenuator to be set directly. When enabled, this feature ensures that the power is stable even if the light source power fluctuates. This option also simplifies test setup, eliminating the need for an external power meter.

Durable and reliable

Flexible and fully programmable, the FTBx-3500 is designed for singlemode and multimode applications and features an extremely rugged design that can operate 24/7 for years without requiring maintenance.
