Home / Mems optical switch attenuation
The MEMS attenuator design achieves highly repeatable optical attenuation over C and/or L bands through a thermally-actuated reflective vane that intercepts light. DiCon's MEMS variable optical attenuator is a high quality VOA based on DiCon's industry proven MEMS mirror technology. These operate by collecting and collimating light from an input fiber and then reflecting this light off of an ultra-stable and reliable, single-axis DiCon MEMS mirror. These products provide the basis for spectrally efficient DWDM transmission utilizing dispersion tolerant modulation, channel monitoring, wavelength switching, remote power control and. These switches exhibit low insertion loss, meaning they cause minimal signal attenuation when routing optical paths. Besides 1 2 and 2 2 switches, rows and matrices of these switches with high port counts are required.
In the evolving landscape of optical communication, polarization-maintaining MEMS optical switches play a crucial role in managing and routing optical signals with precision. These devices leverage
