1310nm Single Mode In-Line Manual Variable Optical Attenuator
The 1310nm Single Mode In-Line Manual Variable Optical Attenuator provides adjustable optical attenuation at 1310nm using a screw-driven mechanism for continuous and repeatable control. It is built with SMF-28e single mode fiber and features a maximum insertion loss of ≤0.5 dB, an attenuation range of 0.5–60 dB, and a minimum return loss of ≥50 dB for stable signal performance. The polarization dependent loss is ≤0.1 dB. The all-fiber in-line design requires no external power, allowing direct integration into fiber optic systems. It supports a maximum continuous optical power of 500 mW and is suitable for laboratory testing, optical measurement, and communication system calibration.
