Electronic Variable Fiber Optic Attenuator - EVOA1550F
Electronic Variable Fiber Optic Attenuator
Product Specifications
The Electronic Variable Optical Attenuator with Power Lock, FC/PC, 1250 to 1625 nm by Thorlabs operates in the spectral range of 1250 to 1625 nm and can handle input power up to 200 mW. Featuring calibration set points at 1310 nm and 1550 nm with user-defined options, it ensures high precision with a digital display accuracy of 5% (Typ.). With an attenuation from 1.5 dB to over 25 dB and a return loss of ≥40 dB, it's ideal for tasks requiring precise power control in optical systems.
