ST Attenuator Female To Male,1dB, 2dB, 3dB, 5dB, 7dB, 20dB Build
Out Atenuator
Description
ST Build out fix 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.
Main application
(1) to control the power level: the output power of the vibration
control in microwave super heterodyne
receiver, to get the best noise coefficient and frequency
conversion loss, then get the best reception.
In the microwave receiver, automatic gain control, improve dynamic
range.
(2) decoupling components: as to the coupling element between the
oscillator and the load.
(3) the relative standard: as a comparison of the relative standard
of power level.
(4) jump attenuator in radar anti jamming: it is a variable
attenuator whose attenuation value can
mutate, usually without introducing attenuation, encountered
outside interference, a sudden
increase in attenuation.
Main features
- Made of attenuation optical fiber, excellent performance
- Simple structure, compact size, easy to install
- Stable performance, high reliability
- Suitable for 1260 ~ 1650nm wide wavelength
- High reflection loss, low insertion loss
