They use less power because they skip the energy-intensive conversion between light and electricity. And they're transparent to data format, meaning the switch doesn't care whether the light signal carries voice, video, or raw data, or what encoding scheme it uses. It just. Fiber-optic switches control light paths within fiber optics, ranging from simple on/off types to complex matrix configurations like 64×64. Every time that light needs to change direction or jump. Your fiber layer doesn't need to sip power all day. Passive-latching optics use energy only while switching, then sit at ~6 W in standby—often reclaiming ~85–90% of “always-on” draw versus motorized cross-connects that hold power to maintain paths (assume ~50 W; validate on site). They differ from traditional electrical switches by manipulating light paths rather than electrical currents. They are used in a wide range of applications, including telecommunications, data centers, industrial automation, and military and aerospace.
