LC/PC Attenautor 10dB 5dB 3dB SMF-28e Fiber, LC/PC Attenuator Female-Male 10dB
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
