670nm Single Mode In-Line Manual Variable Optical Attenuator
The 670nm Single Mode In-Line Manual Variable Optical Attenuator provides adjustable optical attenuation at 670nm using a screw-driven mechanism for continuous and repeatable control. It is built with 630-HP single mode fiber and offers low insertion loss, a wide attenuation range (typically up to 40 dB), and high return loss to ensure stable signal performance. The all-fiber in-line design requires no external power and can be directly integrated into fiber optic systems. It supports optical power up to 100 mW (depending on fiber specifications) and is suitable for laboratory testing, optical measurement, and system calibration.
