Description
1310nm SM MEMS VOA
1310nm SM MEMS VOA (Variable Optical Attenuator) is an optoelectronic products designed for attenuating the optical power, it integrates with a MEMS chip inside to adjust the angle of the reflection prism to achieve the optical power attenuation function, it’s widely used in Quantum Communication system, fiber line protection and Optical Testing System. High power version is also available.
