SC FC LC MU Inline Attenuator, Fixed In-line Fiber Optic Attenuator SM 1Meter Range:1~40dB
Description
Attenuator is in the specified frequency range, a kind of circuit for introducing a predetermined
attenuation.The unit by the decibels which introduced attenation and ohmic characteristic of its
Impedance. Attenuators are widely used in the cable television system in order to meet the
requirements of multi port for electric level such as the amplifier input, output level control,
branch attenuation control.
