ESVOA Series

Electrostatic MEMS Variable Optical Attenuator

The Lumentum Agile Optical Components family includes modulators, switches, attenuators and tunable filters. These products provide the basis for spectrally efficient DWDM transmission utilizing dispersion tolerant modulation, channel monitoring, wavelength switching, remote power control and dynamic channel selection. They support a wide range of flexible functionalities at lower operational expenses for the Agile Optical Network. In addition, we have a complete line of tunable lasers assemblies and sub-assemblies in our Agile Transmission Module family.

Lumentum Electrostatic MEMS Variable Optical Attenuators (ESVOA) focus on key network optical power management applications. Lumentum offers ESVOA series attenuators in normally open and normally closed states. ESVOA series attenuators fully comply with the Telcordia 1221 reliability program. Key features include a small size, low wavelength dependent loss (WDL), and high reliability.

The ESVOA series attenuator achieves highly repeatable optical attenuation over C and/or L bands using an electrostatic rotatable mirror. Applied voltage/power actuates the mirror to rotate, changing the light coupling between the input fiber and the output fiber of the ESVOA series attenuator.
