SKU: HPNA

Engineered for precision laboratory metrology, the HPNA Series VOA measurement grade Variable Optical Attenuator delivers 0.05 dB repeatability and 65 dB attenuation with minimal signal distortion and maintains 55 dB high return loss for single mode by utilizing a true optical absorption mechanism. Unlike conventional mechanical blocking, mirror reflection, or micro-bending methods that alter spatial profiles, this absorption-based architecture preserves launch modal distribution without introducing mode-filtering artifacts — making it ideal for accurate multimode and single-mode device characterizations — while ensuring stable, input intensity-independent attenuation across wide dynamic power ranges. Compatible with SM, MM, or PM fiber, the VOA includes a USB- or RS232- controlled PCB with a GUI and a wall-pluggable power supply.
