When reducing cross-talk, refer to that this interference becomes smaller on surface, but NEXT (dB) value can be got higher, this is because closely Hold the calculation formula of cross-talk are as follows: NEXT=10log10 (P1/P2) (dB), wherein

P1 is the input power of the input signal of proximal end interfering line pair

P2 is the input power for the output signal that proximal end is disturbed line pair

When under the premise of P1 input power is constant, if it is possible to it reduces by crosstalk line to the signal value of receiving, i.e. P2's Input power, this P1/P2 ratio will become larger, then the value of NEXT also can be bigger, thus it is usually anti-in the sense that general push away, i.e., It is smaller to suffered interference by crosstalk line when dB value is higher.

Test value according to near-end crosstalk NEXT is higher, that is, the performance for representing user terminal is better principle, application People after actual measurement 80 have plus isolation bar and network module (PCS) without isolation bar after, obtain following test result:

As seen from the above table: adding the ratio that test value is got higher after isolation bar to obviously increase, and no longer have test value The network module of lower (such as 2-5dB and 5-6dB).And from observing and predicting before reinforcement, take any portion, hence it is evident that visible host side with The worst line in slave end to not being the 1st, No. 2 line-the 4, No. 5 lines (i.e. orange line to 12 with blue line to 13, in slave end NEXT (dB) test value is 5.8), be exactly the 3rd, No. 6 line-the 7, No. 8 lines (i.e. green line to 14 with brown line to 15, in host side The test value of NEXT (dB) is 10.0).Detailed forecasting data is as follows:

Pass through	Host	SR
			Worst line pair	36-78	12-45
NEXT(dB)	10.0	5.8
			Frequency (MHz)	235.5	106.5
Limiting value (dB)	35.8	41.4

Due to the 1st, No. 2 line, the 4th, No. 5 line pair or the 3rd, No. 6 line, the 7th, No. 8 line line pair between it is equidistant, to make line Road compensation is difficult, therefore must set about from the structure that this is isolated, then is experimentally confirmed: by reinforcement technology of the invention, Any portion is taken from observing and predicting after reinforcement, hence it is evident that visible host side and the worst line in slave end are to the 1st, No. 2 line-for being no longer fixation 4th, No. 5 line and the 3rd, No. 6 line-the 7, No. 8 lines, but the 1st, No. 2 line-the 4, (i.e. orange line is to 12 and blue line pair for No. 5 lines 13, be 7.4 in the test value of slave end NEXT (dB)) and the 1st, No. 2 line-the 7, (i.e. orange line is to 12 and brown line pair for No. 8 lines 15, be 8.2 in the test value of host side NEXT (dB)).Detailed forecasting data is as follows:

Pass through	Host	SR
			Worst line pair	12-78	12-45
NEXT(dB)	8.2	7.4
			Frequency (MHz)	238.5	246.0
Limiting value (dB)	35.7	35.5

This is because increase muscle bit main purpose of the invention is to increase when under the premise of P1 this input power is constant Ledger line can also reduce the signal value by crosstalk line to receiving, the i.e. input power of P2 to spacing, reach this P1/P2 ratio The result to become larger.

The size of cross-talk or formed again with a upper line to it is earlier or later with next line to adjacent related, in other words It says, more early adjacent i.e. representative interference is bigger, and the first and second isolation bars 241,242 are exactly to increase a upper line to (orange line To 12 or brown line to 15), from penetrating type terminal 61 to the length being mutually adjacently a little.
