630nm Single Mode In-Line Manual Variable Optical Attenuator
The 630nm Single Mode In-line Manual Variable Optical Attenuator (VOA) is designed for precise optical power control in 630 nm fiber optic systems. It uses a screw-driven adjustment mechanism to provide stable and continuous attenuation. Built with 630-HP single mode fiber, it offers low insertion loss (≤1.5 dB), a wide attenuation range (1.5–40 dB), and high return loss (≥50 dB), ensuring reliable signal control with minimal back reflection. The in-line passive design allows direct integration without external power or additional components. The device supports up to 100 mW continuous optical power and is suitable for applications within the 610–650 nm wavelength range, including laboratory testing and precision optical systems.
