With the intelligent building, intelligent building community on the increasingly high demand for broadband cabling, ultra-Category 5 and Category 6 cable has gradually become the mainstream cabling system. Category 5 and Category 5 cables are 100MHz, but they have the ability to communicate in both directions, allowing users to send and receive broadband information simultaneously.
Therefore, Cat5e cable has more improvement in resistance imbalance, insulation resistance, capacitance imbalance and transmission speed than Category 5 cable, and increases the power consumption of near-end crosstalk and the far-end string Sound power and some other indicators, so the process and structure to do some improvement can be achieved. Category 6 cables on the basis of ultra-5 class, but also improve the transmission band, reaching 250MHz, the corresponding indicators have also greatly improved.
Copper cables have been laid, we can only under existing conditions, make use of its characteristics to open up new digital services. The existing HYA cable, although it can also open a number of new services such as ADSL, but the capacity is limited, when the ADSL number increased to a certain extent, there will still be interference problems, but also affect the previously opened business.
