Description
Technical field
This utility model relates to field of cables, a kind of six type shielding cables.
Background technology
Electric wire in order to transmit electricity (magnetic) can, information and realize electromagnetic energy conversion wire product, the electric wire of broad sense
Being also referred to simply as cable, the cable of narrow sense refers to insulated cable, and it may be defined as: the aggregation being made up of following part；One
Or many insulated wire cores, and the clad that each of which is likely to be of, total protective layer and outer jacket, cable also can have additional
Do not have insulation conductor.In order to transmit electricity (magnetic) energy, information and the wire product realizing electromagnetic energy conversion.The electricity of broad sense
Line cable is also referred to simply as cable, and the cable of narrow sense refers to insulated cable.
The transmission frequency of six class cables is 1MHz～250MHz, and six type routing system is overall attenuation crosstalk ratio when 200MHz
(PS-ACR) should have bigger surplus, it provides 2 times of bandwidth surpassing five classes.The transmission performance of six type routing is the highest
In surpassing five class standards, it is best suited for the transfer rate application higher than 1Gbps.Six classes and the important difference surpassing five classes
It is: improve the performance in terms of crosstalk and return loss, for the highspeed network applications of a new generation's full duplex,
Excellent return loss performance is epochmaking, but the cable tensile strength of existing use is low, and overall using effect is not very
Good.
