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.
- Return loss: UPC > 50 dB, APC > 60 dB
- Attenuation according to definition
- Low ripple broadband design for operation at wavelength range 1250 to 1650 nm
- Fiber (primary coated) or cable version
- Patchcord with connector according to specification
