SKU: HPLA

The HPLA Series VOA is based on moving fiber technology with a precision motor featuring low optical loss. This broad spectral band is only limited by fiber intrinsic properties and precision/repeatability for fibers with large core sizes up to 2mm in diameter. It is designed for high precision and high fidelity measurements with little optical mode dependence. Conventional light deflections and blockings affect light transmission characteristics, but fiber-fiber technology overcomes this by eliminating coating and Lens. The HPLA has two built-in optical position sensors so that once the VOA attenuation value is set, it will remain at the value regardless of the environment variations. It has a high repeatability of 0.1dB and a high resolution. Once powered, it is a latching device that can be operated in vibration environments.
The VOA integrates with a USB or RS232 driving PCB with GUI. A wall pluggable power supply is provided.
