CATV SC Attenuator 10 dB Optical Fiber Single Mode SM, SC FC LC ST MU
Fixed optical fiber attenuator is made of high precision standard dust. Refined. It use for a variety
of optical fiber transmission line, high precision attenuation, stable and reliable performance.
Performance characteristics have no relationship with wavelength change, can realize the adapter
and attenuator both functions.
Due to its attenuation accuracy, high additinal loss,it is used in optical distribution frame, optical
fiber network system, the low speed optical fiber transmission system.
Optical fiber attenuator divide into flange adapter (coupler) type and Female to male or Variable
(VOA) type, according to connectors, can have MU, SC, ST, FC, LC etc..
From the microwave network point of view, attenuator is a two port lossy microwave networks.
It belongs to pass type microwave components.
