What is a fiber optic attenuator?
An attenuator is a device that is used to reduce signal amplitude by a known amount without introducing distortion. Attenuators are installed in fiber optic systems to keep the power level within the limits of the receiver’s detector.
Do I need a fiber attenuator?
Generally, multimode systems do not need attenuators as the multimode sources, rarely have enough power output to saturate receivers. Instead, single-mode systems, especially the long-haul DWDM network links, often need to use fiber optic attenuators to adjust the optical power during the transmission.
What is 5dB attenuator?
This Fiber Optic Attenuator, Fixed – LC/UPC 5dB is necessary to prevent over saturating an optical receiver when the optical power is too high. Using attenuators will ensure low bit error rates and prevent damage to receiving components. LC male-female, 5db…
How does a variable optical attenuator work?
Optical attenuators usually work by absorbing the light, like sunglasses absorb extra light energy. They typically have a working wavelength range in which they absorb all light energy equally.
What does attenuator mean?
Definition of attenuator : a device for attenuating especially : one for reducing the amplitude of an electrical signal without appreciable distortion.
Can single mode fiber be too short?
The LX single-mode SFPs I use are similar, in that the receive power threshold is above the maximum output power range, so they work just fine with a short fiber, or up to 4 kilometers.
What is a variable attenuator?
A variable attenuator is a circuit that decreases the strength of the input signal either continuously or step by step without appreciable signal distortion while substantially maintaining constant impedance match.
What is the function of attenuator?
Attenuators are electrical components designed to reduce the amplitude of a signal passing through the component, without significantly degrading the integrity of that signal. They are used in RF and optical applications.
How do you get attenuation?
The amount of attenuation in a given network is determined by the ratio of: Output/Input. For example, if the input voltage to a circuit is 1 volt (1V) and the output voltage is 1 milli-volt (1mV) then the amount of attenuation is 1mV/1V which is equal to 0.001 or a reduction of 1,000th.
Why would you use an attenuator?
Attenuators are generally used in radio, communication and transmission line applications to weaken a stronger signal. Resistive attenuators are used as volume controls in broadcasting stations and also can be used for matching circuits of different resistive impedances.
What are the types of attenuator?
Types of Attenuator
- Fixed Type. In Fixed type attenuators the resistor network is locked at a predetermined attenuation value.
- Step Type. These attenuators are similar to fixed attenuators.
- Continuously Variable Type.
- Programmable Type.
- DC Bias Type.
- DC Blocking Type.
- Optical Attenuators.
