JDS Uniphase HA1 – HA1503-046

The JDS Uniphase HA1503-046 is a high-performance optical attenuator engineered for precise power control across telecommunications and data networking systems. This single-mode fiber attenuator delivers attenuation to 100 dB with 0.001 dB resolution and ±0.1 dB accuracy, enabling demanding metrology tasks including bit error rate testing, power meter calibration, and fiber link loss simulation. The device combines wide wavelength coverage, low insertion loss, and exceptional return loss performance with both front-panel keypad control and remote command capability via GPIB and RS232 interfaces.
