Wiring project acceptance test and network test in the near future work have a lot of jump line related trouble and problems, some of the "original jumper" is false and inferior handmade products. The cognition of jump line quality control, in the aggregate, or major problem.
End-to-end network equipment of communication link in the standard is defined as the Channel (Channel). Transmission channel of some key parameters such as near end crosstalk (NEXT) and return loss (RL) affected by users as well as equipment jumper is very big. And for many years, the acceptance of work mainly permanent link model to test. When wiring system to provide network application service requires end-to-end performance guarantee, this usually requires the whole wiring link end-to-end Channel Channel certification test. But there is a simple method to simplify secondary certification test, is to link the new add the jumper wire for certification test. In principle when a fixed part of the channel link through a permanent link test, jump line part through special jump line standard test, then the channels through link is sure to certification test, so in practice is no need to spend a lot of manpower and recertification test was carried out on the channel, but only need to adopt the jumper wire for special standard certification test.
The key problem here is to make a special standard of jump line certification test (rather than the general standard of channel test), to test whether the jumper wire up to the standard stipulated in the index, it must use specially designed adapter, Fluke DTX series of jump line test adapter DTX - PCU6S provides a feasible and correct method to check whether jump line conform to the standards prescribed by the performance index.
DTX - PCU6S jumper test option is based on TIA and ISO/IEC standard to test the Cat 5 e and Cat 6 jump line. DTX - PCU6S jumper test suite includes links to DTX DTX - PCU6 / host adapter on the far side of MN adapters and connection to the DTX DTX - PCU6 / SR. Test adapter meet TIA/EIA - 568 - B. The test socket indicators stipulated in the 2-1.
Test parameters include: the wiring diagram, ensure the correctness of the line to connect; Transmission delay, the length and the time delay difference; (one-way) near end crosstalk (NEXT) and return loss (one-way). Accuracy of measurement is based on TIA/EIA - 568 - B. 2-1 and IEC 61935-1 of the regulations, calculated. The worst accuracy is based on the precision of level III strict requirements.
After tests proved that these test adapters in continuous since 15000 can still provide a stable contact resistance. Socket in the gold-plated surface layer after so many plug could be rub off completely, but gold plated layer does not increase or reduce the key near end crosstalk (NEXT) and return loss (RL) parameters of performance. Test only need 9 seconds, then connect the new jumper, insert the clean connection point during the sliding process. So generally do not have any corrosion or long-term contact resistance of aging.
Conclusion:
Jump line of jump line and equipment for data transmission network performance has a crucial influence. To be sure we all hope the installed high-speed data link, such as Cat 5 e/Class D or Cat 6, can support higher bandwidth and reliably provide high-speed data transmission. Unfortunately, in the building wiring system user jumpers were ignored. These jumpers are usually installed in a permanent link or fixed cable link after months or years later to buy separately. And these jumpers may only be based on the price to consider to choose and buy, so ignore the consciousness of the often become the fault source of network application. In the actual test we can quickly complete test users for 6 seconds jump line or equipment jump line of work, for quality and time, the true and false difficult points now jump line market, it is concerned with the quality of jump line unit "shine on a demon mirror".
