Programmable Variable Optical Attenuator

This programmable variable optical attenuator is a next-generation instrument designed for precise control of optical attenuation via the PO port. Featuring an innovative design and advanced circuitry, it provides continuous adjustable attenuation from 0 to 65dB across a wide single-mode wavelength range of 1260nm to 1650nm. With exceptional reliability and stability, it also includes an optical shutter function to enable users to cut off the optical path as needed. This optical attenuator is ideal for testing and debugging during the development and production of fiber communication systems, devices, and instruments. The programmable variable optical attenuator is the perfect solution for professionals in fiber optics who demand precision, stability, and flexibility in their testing environments.
