1480nm Polarization Maintaining In-Line Manual Variable Optical Attenuator
The 1480nm Polarization Maintaining In-Line Manual Variable Optical Attenuator (VOA) is a precision optical device designed for accurate power control while maintaining the state of polarization (SOP) in polarization-sensitive fiber systems. Operating in the 1480nm wavelength range, it provides smooth and stable attenuation with low insertion loss and high return loss.
Built with PM1550 polarization maintaining (PM) fiber, this in-line VOA ensures high extinction ratio and minimal signal distortion during attenuation, making it ideal for applications requiring strict polarization control. Its compact structure and reliable manual adjustment mechanism allow precise optical power tuning without interrupting the transmission path.
