The JDS Uniphase OLA-55M is a motorized optical level attenuator for single-mode fiber systems engineered for testing, installation, maintenance, and production environments. This device combines optical attenuation with integrated power metering, enabling direct setting of output power levels and automatic compensation for input power fluctuations through Level Controller Mode. The attenuator eliminates the need for external power meters during power level adjustments, streamlining field and lab workflows.
