1480nm Single Mode In-Line Manual Variable Optical Attenuator
The 1480nm Single Mode In-Line Manual Variable Optical Attenuator (VOA) is a precision device designed to manually adjust optical signal power in single mode fiber systems. Operating in the 1480nm wavelength range, it provides smooth and continuous attenuation with low insertion loss and minimal polarization dependent loss.
Built with SMF-28e fiber, this in-line VOA ensures stable and repeatable attenuation performance, making it ideal for fine power control in optical testing, system balancing, and signal optimization. Its compact and robust design allows easy integration into fiber networks without interrupting the optical path.
