NEXT

Power sum NEXT (PS NEXT)

Attenuation to crosstalk ratio at the near-end (ACR-N)

4.2 Definition of the testing parameters

4.2.1 Insertion loss

SMZ

Transmitter

Receiver

A B

Core pair

Definition The attenuation is determined by the ratio of the power supplied to the port A and the measured power at the port B as specified below:

B

AV

P

P log 10 = [dB] a

Both the input and the output of the two-port network must be terminated with the nominal impedance.

Influencing variables In case of cables, the attenuation is primarily determined by the cross-sectional area and the conductivity of the copper wires. Especially in high frequency ranges, the attenuation is increased by the dielectric losses of the core insulating material.

The attenuation is dependent on the length, the frequency, and the temperature.

Significance A low attenuation improves the transmission reliability of the cabling system. The attenuations of cables and connecting devices are accumulative although they are largely dominated by those of the cables.

Definition The near-end crosstalk attenuation is determined by the ratio of the power supplied to the port A and the measured power at the port B as specified below:

B

ANEXT

P

P log 10 = [dB] a

Both sides of the specimen must be terminated with the nominal impedance. In the event that the sender and the receiver are located at the same end of the specimen, we are speaking of near-end crosstalk (NEXT) attenuation.

Influencing variables In case of cables, the near-end crosstalk attenuation is primarily determined by the twisting of the cores and (if existing) the paired foil screens.

The near-end crosstalk attenuation is largely dependent on the frequency and – to a minor degree – also on the lengths.

Significance A high near-end crosstalk attenuation improves the reliability of transmissions. Within the cabling system, the reliability of transmissions is primarily determined by the component having the lowest near-end crosstalk attenuation.

Definition The power sum of the near-end cross-talk is defined on the basis of the ratio of the power input at the three pairs A, B and C to the power output at pair D. The power-sum NEXT value of cables can be measured by means of a phase-correlated 4-port power splitter. On the basis of the pair-to-pair NEXT measurements, the power sum can also be calculated according to the following formula:

3

1i

0,1-

10 log 10 = [dB] aiNEXTa

PSNEXT

Influencing factors The power-sum NEXT value of cables is decisively influenced by the stranding and the foil pair shield (if applicable). Power-sum NEXT strongly depends on the frequency used and – only to a minor extent – on the cabling length.

Meaning With regard to network protocols that distribute the bi-directional data load over all four pairs, power-sum NEXT is of great importance for transmission reliability since power-sum cross-talk is expected to impair transmission via the data channel.





4.2.4 Attenuation to crosstalk ratio at the near-end (ACR-N)

Definition The ratio of the level of the incoming useful signal to the noise level at the opposite end of the measured link is referred to as Attenuation-to-Cross-Talk Ratio (abbr. ACR).

ACR may be interpreted as the signal-to-noise ratio with the near-end cross-talk being regarded as the interfering signal or noise.

[dB] a - [dB] a = [dB] ACR VN

Calculation As agreed, the ACR value is calculated for every frequency response of the near-end cross-talk with the two relevant frequency responses of the attenuation.

Alternatively, the minimum value of the ACR calculation may be allocated for every measuring point of the two attenuation values involved. The determination of the double-ended system dynamics thus results in 12 ACR frequency responses for a four-pair specimen.

Meaning The ACR value is of decisive importance to system designers, system manufacturers and operators of data communications equipment since it provides immediate insight into system dynamics and system reserve. The larger the distance between the useful signal and the noise signal over the entire frequency range, the larger the infrastructural reserve.

4.2.5 Power sum ACR-N (PS ACR-N)

Definition The power sum of the ACR reserve is calculated as follows:

PS ACR [dB] = aPSNEXT [dB] – aV [dB]

Meaning With regard to network protocols that distribute the bi-directional data load over all four pairs, power-sum ACR is of great importance for transmission reliability since cross-talk is expected to impair transmission via the data channel.





4.2.6 Attenuation to crosstalk ratio at the far-end (ACR-F)

Definition The equal-level far-end cross-talk (abbr. EL FEXT) is determined by the ratio of the power measured at the remote port B to the power measured at the remote port C. The measuring signal is supplied to the near end of the cable.

C

BELFEXT

P

P log 10 = [dB] a

All pairs of the EUT are terminated with their characteristic impedance.

Influencing factors The EL FEXT value of cables is decisively influenced by the stranding and the foil pair shield (if applicable).

EL FEXT strongly depends on the frequency used.





4.2.7 Power sum ACR-F (PS ACR-F)

Definition The power-sum EL FEXT value can be calculated on the basis of the pair-to-pair EL FEXT measurements according to the following formula:

3

1i

0,1-

10 log 10 = [dB] aiELFEXTa

PSELFEXT

Meaning With regard to network protocols that distribute the bi-directional data load over all four pairs, power-sum EL FEXT is of great importance for transmission reliability since cross-talk is expected to impair transmission via the data channel.





4.2.8 Return loss

R = Z

Differential-mode termination

Definition The return loss represents the ratio of the power supplied to the EUT to the power reflected by the EUT.

output

input

RP

P log 10 = [dB] a

The EUT end is terminated with the characteristic impedance in order to absorb any non-reflected power. The EUT and the test-value transmitter must have the same rated impedance in the broadband range.

Influencing factors The return loss value of cables is decisively influenced by the homogeneity of the conductors and the core of the cable. Mechanical load during the manufacturing or installation of the cables may impair the return loss.

The parameters return loss and characteristic impedance correlate.

Meaning A high degree of return loss improves the transmission reliability. A low degree of return loss may lead to an unwanted overlap of returning signal components.





4.2.9 Propagation delay

SMZ

SMZ

Baluns

Transmitter

Receiver

A B

Pair of Cores

Definition The velocity of propagation v of cables is stated in relation to the maximum velocity of propagation of electromagnetic waves in the vacuum co. The parameter "Nominal Velocity of Propagation" (abbr. NVP) is defined as follows:

NVPv

oc

The delay is the period of time the signal requires in order to travel through a cabling link with a length of l. The delay is calculated on the basis of the NVP value (Nominal Velocity of Propagation) of the cable and the velocity of light c0 according to the following formula:

cNVP

l

0

Influencing factors The delay of cables is decisively influenced by the dielectric loss of the core insulation material. This material-induced loss may be minimised by selecting various compounds and by varying the degree of foaming.

The impact of colour addition on the NVP value is not to be neglected since the colours vary strongly in their dielectric constants, which are considerably higher than in the basic compound.





Influencing factors

(continued) The velocity of propagation does not depend on the cable length and may be calculated on the basis of the measurement of the length-dependent group delay. The reference length used for calculation is the cable length and not the lay length of the twisted pairs. Different lay length values in the four pairs lead to different NVP values.

Meaning In order to ensure distortion-free signal transmission, the velocity of propagation must not fall below a lower limiting value, which is determined by the system requirements. The velocity of propagation has to be virtually independent of the frequency within the signal bandwidth in order to avoid a divergence of the spectral signal components.

High-bit rate network protocols that use parallel data transmission via the four pairs, moreover, require a highly consistent velocity of propagation in order to avoid synchronisation errors. Future normative standards will define this so-called "delay skew".

4.2.10 Delay skew

Definition The delay skew of cables with a length of l marks the time difference between signals travelling along the individual transmission links at the propagation velocity vi,j.

= li j

i j

v v

v v

Influencing factors The delay skew of cables is decisively influenced by the dielectric loss of the core insulation material and the various lay length values.

Meaning The delay skew will be an important parameter for a distortion-free data transmission in balanced cables in view of future network protocols.





4.2.11 Coupling attenuation

Definition Coupling Attenuation is the relation between the transmitted power through the conductor and the maximum radiated peak power, conducted and generated by the excited common mode currents. The measurement is independent of the bandwith and shall be measured form 30MHz up to 1GHz.

Influencing factors The Coupling Attenuation is primarily determined by the mechanical structure of the component. The Coupling Attenuation is very much dependent on the frequency.

Meaning The better the effectiveness of the Coupling Attenuation is, the smaller is the value of the noiseresistance.
