SFT-A In-Line attenuator Wavelength Independent

The SFT-A In-Line attenuators provide a fixed level of attenuation and feature excellent return loss in wide range of working wavelengths. Low cost and performance determine them for universal using in optical networks.

The SFT-A attenuator can be used as attenuation patchcord – cable 2.8 mm or secondary coated fiber 0.9 mm and primary coated fiber installed inside the splice cassette.
