German term or phrase: Planungsdämpfung

Aus einem Leistungsverzeichnis, Bereich "Glasfaserkabel"

Planungsdämpfung
Die Dämpfung muss kleiner sein als die
Planungsdämpfung A welche vom AN nach folgender Formel
zu bestimmen ist: A = ?L + ?s k + ?c n

hierbei sind:
A Planungsdämpfung [dB]
? ?Dämpfungsbelag der Faser [dB/km]
L Länge der Faserstrecke [km]
?s Mittelwert der Spleissdämpfung [dB]
k Anzahl Spleissverbindungen
?c Mittelwert der Steckerdämpfung [dB]
n Anzahl Steckverbindungen

English translation:intended attenuation

Explanation:
IEV number 312-06-06

--------------------------------------------------------------------------------

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.
DE Dämpfung

B.1. Anforderungen an LWL-Strecken
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.
http://www.bur.uzh.ch/dienstleistungen/downloads/RL236_UKVVe...

ISO/IEC 11801 enthält keinen englischen Begriff für Planungsdämfung, dafür aber eine Definition der Dämpgung(sarten):
3.2
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.

Bie Planngsdämfung handelt sich um die voraussichtlich vorhandene oder rechnerisch ermittelte Dämpfung.

For intended attenuation profile see Fig. 6:

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.

FIG. 3 illustrates a design attenuation characteristic of a typical telephone transmission line, in accordance with a CCI recommendation.

(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.

2 hrs confidence:

circuit loudness rating

Explanation:
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(s):

CLR Circuit loudness rating: the loudness loss between two electrical interfaces in a connection or circuit

2 hrs confidence:

link loss budget

Explanation:
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.

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