well both attenuation and crosstalk are used extensively in communications especially in data communications.
the difference between the two is how they both affect signal or intelligence run across a media from a point of origin to a destination.
attenuation is the degradation of the signal due to various reasons such as noise introduction, lossy media, distance, and the like.
crosstalk however is the interference of signal to an adjacent one whereby affecting the signal's essence. usually cause by radiation of electromagnetic induction run through a media usually copper.
usually a high frequency transmitted over a wired media causes crosstalks to adjacent ones if proper shielding is neglected, however attenuation may also occur if the signal is projected towards a lossy media over a long distance and with the presence of noise.
both are always introduce in a communication environment but have their differences where one degrades while the other affects signal.
A UTP network cable consists of four 'pairs' of wires. The two wires in each pair are twisted around eachother to help provide immunity to interference. If we consider a signal being sent down one pair in isolation, then the attenuation of the cable is the degree to which the signal gets reduced in magnitude as it travels down the cable and comes out the other end. As mentioned, this causes degradation of the signal because as you get less and less signal then the noise, interference etc also present on the cable becomes more significant and can corrupt the data.
Crosstalk is the extent to which a signal sent down one pair of the cable also appears on another pair. The cross-coupling occurs by electromagnetic induction, and the 'unwanted' signal due to the crosstalk also contributes to the noise on the pair that competes with the wanted signal. The twisting of the pairs aims to reduce the induction, lowering both the crosstalk between the pairs within the cable and interference induced from outside. What determines the attenuation is a little more complex, but basically it's to do with how the construction of the cable matches the frequency being used. The higher the data rate (anf hence frequency of the signal) the 'better' the cable has to be and the tigher the manufacturing tolerances

What is the difference between noise and attenuation?
Noise (as related to a radio signal I suppose) is an unwanted signal being processed by a receiver. Attenuation is a loss of the intended signal before it gets to the receiver (usually due to such things as distance, line of sight obstructions, etc.
What is a good value for dB attenuation?
6 dB is a "good" attenuation.
How do you reduce attenuation effects?
We can reduce attenuation effects bt using repeaters
What is breast attenuation as in nuclear stress test?
breast attenuation correction meethods
Does Fiber Optic lines are immune from crosstalk?
Yes.
Difference between attenuation constant and phase constant?
nothing
What Is The Difference Between Crosstalk And Ghosting?
Crosstalk is the incomplete isolation of the left and right image channels so that one leaks (leakage) or bleeds into the other, looks like a double exposure. The perception of crosstalk is called ghosting Technically, crosstalk is a physical entity and can be objectively measured, whereas ghosting is a subjective term Another way to think about it: 100% crosstalk is where you're not wearing glasses at all.
What is the difference between attenuation and insertion loss?
In CATV system, insertion loss define as loss in directional coupler or TAP connector. typically 1 dBuv, while attenuation is generally describe as loss in transmission (splitter).
What is the meaning of the term crosstalk?
Interference of signals between wire pairs.
What is the difference between noise and attenuation?
Noise (as related to a radio signal I suppose) is an unwanted signal being processed by a receiver. Attenuation is a loss of the intended signal before it gets to the receiver (usually due to such things as distance, line of sight obstructions, etc.
What is the difference between RG11 and RG213 cable?
RG-11/U is 75ohm and is usually triple/quad shielded and typically has a maximum attenuation of 3.65. RG-213/U is common form amateur radion and is 50 ohms and is single shielded with about a 5.95 attenuation.
What is meant by homowavelength?
homowavelength crosstalk is a crosstalk that occur on a single wavelength.
What is the difference between first order low pass filter and second order low pass filter?
in second order filter attenuation to the frequencies in stop band is higher then first order filters.
What are the ratings and certificates for Crosstalk - 1982?
Crosstalk - 1982 is rated/received certificates of: Australia:M Iceland:12
How can you reduce crosstalk?
Reducing crosstalk depends on where the crosstalk is occurring. In adjacent channels on something like, say, a microwave link, polarizing the signals on adjacent channels alternately works pretty well. There are other ways, and lots of other places where crosstalk can appear. Just one was cited.
Which procedure is used to reduce the effect of crosstalk in copper cables?
designing a cable infrastructure to avoid crosstalk interference
