850nm Multimode In-Line Manual Variable Optical Attenuator
The 850nm Multimode In-Line Manual Variable Optical Attenuator provides adjustable optical attenuation at 850nm using a screw-driven mechanism for continuous and repeatable control. It is designed for multimode fiber systems and supports OM1/OM2/OM3/OM4 fibers. The device features a maximum insertion loss of ≤0.8 dB, an attenuation range of 0.8–60 dB, and a minimum return loss of ≥30 dB. The polarization dependent loss is ≤0.1 dB. The all-fiber in-line design requires no external power, allowing direct integration into multimode fiber optic systems. It supports a maximum continuous optical power of 500 mW and is suitable for testing, measurement, and system calibration.
