EN attenuation
ratio of the input to the output values of quantities of the same kind in a device or system
NOTE – When this ratio is less than unity it is usually replaced by its reciprocal, the gain.

Anforderung: Verkabelungsstrecke der Klasse LWL, gemäss ISO/IEC 11801
Zusätzliche Anforderung:
ñ Dämpfung kleiner als Planungsdämpfung.
ñ Das Gesamtverkabelungssystem (Stecker, Panel, etc.) muss dem Standart ANSI/TIA/EIA-568-B3.1
Fiberklasse OM3 entsprechen.

attenuation (insertion loss, composite loss, operational attenuation and S21)
ratio of the unreflected square root of power P0 into a cable assembly to the square root of power P2 into the load.

A design procedure was newly developed for the control of the TO phase shifters, which could be used to accurately control the intended attenuation profile in one adjustment.

We find that an input microwave power of PRF = −31 dBm corresponds to n = 1 which is consistent with an intended attenuation of approximately 105 dB in the input coaxial line.

(a) For proper shielding effectiveness, it is recommended that the
manufacturer's advertised design attenuation be specified when it exceeds 50 decibels, rather than using the shielding effectiveness-versus-frequency curve shown in figure 8-4.

circuit loudness rating
This is a term from telecommunications, which I assume your text is about?
I've had all these 'loudness rating' terms in a translation about VoIP recently, so I think this must be the one. Unfortunately I cannot quote from it now because I have it on another PC...

Example sentence:

link loss budget
This link says:
A fiber optic link budget, also known as a "loss budget," indicates the total acceptable amount of optical power loss (expressed in decibels) that a fiber optic link can have. These losses result from cables, connectors, splices, couplers and equipment in the installed system. Loss budgets are typically determined in the network design stage.
and this is how I would phrase it in USA English.
You might want to look around the site for more vocabulary.

: This is essentially the same as Bernd's second recommendation with reference. Since Bernd was 3 min. and you 2 hrs. I'd have to agree with him, if he had only listed it as the answer.

Da ich bei meinem ersten Versuch meinen eigentlichen Favoriten erst als "Zweitnennung" gepostet habe, nehme ich diesen zweiten Anlauf.

Die Planungsdämpfung wird berechnet aus der Dämpfung der Faser, der Dämpfung von Spleissen und den Dämpfungen von Steckerübergängen. Das Einhalten der Planungsdämpfung ist eine Kontrolle für die fachgerechte Verarbeitung und Verlegung.
