Fiber Optical Attenuator
 
Company Info
1550nm 1G fiber optic transceiver

The Most Important Feature and Application of Fiber Attenuator

The most crucial spec of an attenuator is its attenuation versus wavelength curve. Attenuators should have the same impact on all wavelengths used in the fiber system or at least as flat as possible. For instance, a 3dB attenuator at 1500nm should also lessen the concentration of light at 1550nm by 3dB or as close as possible, this is also true inside a WDM (Wavelength Division Multiplexing) system.

The Fiber Attenuator Can be used with FTB-104C and FTB-106C whitch are both belong to Sopto FTTH fiber terminal box, FTB-106C is the upgrade version of FTB-104C, they have the same design, size, appearance, constructer, material and function, the only difference between them is the capacity, FTB-104C can be installed in 4 pieces of SC simplex adaptor and FTB-106C can be installed 6 pieces of SC Simplex adaptor.
