EXFO FVA-60B Optical Variable Attenuator

The Exfo FVA-60B Variable Attenuator performs just as well in a laboratory environment as it does in the field, offering three attenuation display modes. This handheld variable attenuator performs just as well in a laboratory environment as it does in the field. Superior specifications (±0.15 dB linearity from 2.5 to 70 dB, 0.05 dB resolution and ±0.10 dB repeatability) make it the variable attenuator of choice for various applications. For lab or field work flexibility, choose the Exfo FVA-60B Variable Attenuator. The Exfo FVA-60B offers three attenuation display modes: Absolute (including insertion loss), Relative (in reference to 0.00 dB level) and 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). Operate the Exfo FVA-60B remotely from your PC using the standard RS-232 interface and control codes. Program software solutions are adapted to your testing needs. The Exfo FVA-60B 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. The Exfo FVA-60B enables consistent operation in various manual or automated testing situations, such as BER testing, system testing and acceptance, power meter calibration and verification, optical margin analysis, system loss simulation, as well as field, manufacturing and R&D applications.

*This is a Web introductory price for one calibration of the EXFO FVA-60B. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Amplified Spontaneous Emission Source (ASE)
ASE, a process where spontaneously emitted radiation (luminescence) is amplified. In lasers and particularly in high-gain erbium-doped amplifiers, amplified spontaneous emission is usually an unwanted effect. It tends to limit the gain achievable in a single stage of a fiber optic amplifier to the order of 40–50 dB.

Dynamic Range
In a transmission system, the ratio of the overload level to the noise level of the system, usually expressed in dB. Ratio of the highest to lowest detectable signal of a system, expressed in dB.

Optical Power
Optical Power is usually measured in "dBm", or decibels referenced to one miliwatt of power. while loss is a relative reading, optical power is an absolute measurement, referenced to standards. You measure absolute power to test transmitters or receivers and relative power to test loss.

Relative Wavelength Accuracy
When randomly changing the wavelength and measuring the differences between the actual and displayed wavelengths, the relative wavelength accuracy is ± half the span between the maximum and the minimum value of all differences.

Wavelength
Wavelength is a term for the color of light, usually expressed in nanometers (nm) or microns (m). In Fiber Optics the wavelenghts mostly used are in the infrared region where the light is invisible to the human eye.
