Benchtop Digital Multichannel Variable Attenuator

Feb. 5, 2019

OZ Optics Limited, a global supplier of fiber optic products for all applications, has introduced a new line of bench-top test instruments. These instruments feature premium performance, making them ideal for component and device testing. Touch screen interfaces, built-in memory and USB 2.0 communication/controls give the user the functionality to streamline and automate the measurement process, while offering unprecedented accuracy.

Bench-top multichannel variable attenuators feature a capacity to control optical power for up to 4 independent channels. The unit is available not only for telecommunication wavelengths, but also for wavelengths from 350nm to 2050nm, and works with singlemode, polarization maintaining and multimode fibers. A computer interface enables users to access or remotely control the unit through a PC. Reliable and repeatable test results are ensured through the use of the built-in power meter and power stabilization function that sets and maintains output power stability, even when there are input power fluctuations. This makes it ideal for bit error rate testing, trouble shooting receivers and other active fiber optic components, simulating long distance fiber transmission, design of fiber optic transmitter/receiver circuitry, power meter linearity checks, and power setting. With up to 60dB dynamic range (for SM and PM fiber applications) and a broad list of features, the Benchtop Digital Multichannel Variable Attenuator is a vital tool for optical systems.
