FVA-3800

Rugged and Reliable

The rugged and reliable design of the FVA-3800 is built using components with high mean-time-between-failure (MTBF)specifications. Thanks to minimal maintenance, our attenuators can be used in 24/7 production environments.

Power Stabilization

The power monitoring function is used to set the attenuator output power level. When enabled, this option maintains power stabilityeven when there is a fluctuation in source power. It also simplifies test setups by eliminating the need for an external power meter

Polarization-Maintaining Option

The FVA-3800 is compatible with polarization-maintaining fiber. This eliminates the need to use an external polarization controlleto maintain the polarization of the input signal, which is critical for coherent transmitters, receiver design and testing.

SIMPLE, FLEXIBLE AND USER-FRIENDLY INTERFACE

Front Panel Control

Equipped with an LCD display, the FVA-3800 does not require a PC to set the attenuation range, wavelength or power outputlevel. This makes it fast and easy for users to set all the required parameters.

PC Application for Multi-Instrument Management

EXFOs Test Instrument Manager application, TIM, makes it very easy for users to control and view the status of each attenuatorSimply connect a PC running the application to the FVA-3800 via USB, for single device operation, or connect via Ethernet, fomulti-device operation.

The TIM application is also compatible with the FLS and IQS-2800 ITLA tunable light sources.

Remote ControlStandard USB and Ethernet interfaces enable the FVA-3800 to be remotely controlled from a PC or test station. This allows usersto program their own software solutions for complex procedures or to automate their testing using SCPI commands.

VERSATILE AND COMPACT SIGNAL ATTENUATION SOLUTIONThe FVA-3800 Multiport Benchtop Optical Variable Attenuator is designed for a broad range of applications for users with verydemanding research requirements as well as for those looking for a fast, high-density solution.

It is the most compact instrument on the market. Capable of integrating up to four attenuators in a single unit, users with tightspace requirements are now able to get a no-compromise solution.
