Too strong a signal can damage the cable modem?
The technician from Magenta/Telekom said when installing the cable and socket in my new apartment that he also had to install a signal attenuator, otherwise the signal would be too strong and the modem would be damaged over time…
I've never heard of anything like this happening.
Why is that, if the modems can't handle it?
And shouldn't it break quickly if it does (overvoltage/current)?
At the input is a signal amplifier/LNA when its output signal becomes too high and the power loss becomes too high.
This then leads to an overtemperature and destruction of it. How fast this depends on many factors, but the problem is idr schleichend. So if it becomes defective slowly, its output signal becomes either weaker or more distorted.
At some point, the circuit behind it can no longer process the signal.
This is not a sudden overvoltage or the like, but an overload effect. Compare it with music boxes when the are overdriven at full volume they begin to snore with time and the sound gets worse and worse.
Overvoltage is actually a possible factor. More frequently, however, dampers are not used to protect devices, but simply to ensure that an excessively strong signal is in optimal quality and thus ensures a connection that is as stable as possible without oversteering and thus causing connection interruptions or data losses.
Overvoltage in the sense it does not have to be, but an overdriven amplifier can burn through.
Since LNAs are now working with a few componets to be out-of-the-box, they are also broken by overcontrol.
Hello,
as you write “Magenta”: What country are you from?

Austria.
I thought.
So that overvoltages can damage hardware is as correct as possible. So it must be meant, because an excessive reception signal – I actually hear for the first time. I don’t know if you have other technical standards.
