EXFO FVA-60A Variable Optical Attenuator

Lab and Field Versatility This portable variable attenuator performs just as well in a laboratory environment as it does in the field. Superior specifications make it the variable attenuator of choice for a number of applications. For lab or fieldwork flexibility, choose the FVA-60A.

Features

• Up to 70 dB attenuation
• Typical 2.5 dB insertion loss
• Automatic attenuation sequence with Program mode
• Standard Universal Interface

Three attenuation display modes

• Absolute (including insertion loss)
• Relative (in reference to 0.00 dB level)
• x + b (arbitrary value)

Program mode: Cycles through a repeatable sequence of up to 60 attenuation steps, pausing for one second or up to 60 hours at a time. The Program mode is particularly suited to accelerated bit-error-rate (BER) testing.

Fourteen available wavelengths Matches your source wavelength to the nearest 10 nm for unbeatable accuracy.

Variable scanning speed Scans the complete attenuation range at four different speeds according to the selected step size (0.05, 0.20 or 1.00 dB/step and variable step size).

Remote Control Capability Operate the FVA-60A remotely from your PC using the standard RS-232 interface and control codes. Program software solutions are adapted to your testing needs.

Three-Way Powering Goes a Long Way The FVA-60A features three complementary power sources for extended operation: a rechargeable NiCd battery, a 9 V alkaline backup battery and an AC adapter/charger for continuous operation.

Exceptional Specifications High-quality optical components make the FVA-60A Variable Attenuator the standard for performance and flexibility. EXFO’s computer-assisted calibration techniques deliver remarkable specifications:

• ± 0.15 dB linearity
• 0.05 dB resolution
• ± 0.10 dB repeatability

Multiple Applications The FVA-60A enables consistent operation in various manual or automated testing situations.

• BER testing
• System testing and acceptance
• Power meter calibration and verification
• Optical margin analysis
• System loss simulation
• Field, manufacturing and R&D applications
