SC Flange Attenuator

SKU 8a82dd4954bd Categories ,

This series of Flange attenuator has the same appearance as a regular fiber optic adapter.
It achieves attenuation of optical signal by setting up an attenuation film inside a fiber
optic adapter to ensure incomplete touch with fiber connectors. Due to this principle,
the Flange attenuator is a great fiber optic attenuation solution for fiber optic patch
cords in an optical link.
As a trusted and dedicated manufacturer of fiber attenuators, we can supply a wide
selection of adapter type Flange attenuators. These fixed optical attenuators are only
suitable for fiber optic connectors with PC type ferrule end face. The attenuation value
can be 1, 3, 5, 7, 10, 15 and 20dB, and thus our fixed attenuators are applicable for optical
signal with wavelength ranging from 1250nm to 1600nm.

  • Excellent Changeability and Directivity
