OA1 | Optical Attenuator

The OA1 Optical Attenuator enables precise optical power control featuring high accuracy and superior repeatability.

The OA1 is ideal for lab and production applications including power level adjustment in automated test systems, Bit Error Rate Testing (BERT) of transmitters and receivers, and channel equalization in WDM systems.

The OA1 Attenuator offers 0.01dB repeatability and a dynamic range of up to 100 dB (depending on the model configuration). The OA1 can be controlled via the front panel touch screen, or remotely via USB & Ethernet.

OA1 series attenuators operate from 1300-1700 for singlemode and 750- 1700 for multimode. A power monitoring PD can be added to read the power output of the instrument. The monitoring PD can also be used to auto adjust the attenuation for a constant customized power level.
