Abnormal signal attenuation means that the signal has been on the wire, but the signal strength in reducing There are many reasons to cause this problem, the main line connection or the cable is too long. The table below is the technical specifications of the cable length. This is the standard maximum length of a variety of connection. Remember that these standards, if your cable connection does not exceed this standard, you still encounter the problem of signal attenuation, you should check the cable itself. Any unnatural bending or inappropriate terminal will cause signal attenuation.

Ethernet cable summary

Technical specifications of the maximum length of cable type

10BaseT unshielded twisted pair 100 m

10Base2 thin coaxial cable 185 m

10Base5 thick coaxial cable of 500 m

The 10BaseF fiber 2000 m

100BaseT Unshielded Twisted Pair 100 meters

100BaseTX Unshielded Twisted Pair 220 meters

For unshielded twisted-pair crosstalk will surely lead to serious problems as well as signal attenuation. Reduced isolation or barrier between the two signals in two pairs of children the cable signal interference, so it was a cross-talk. Also occur when the same cable used for a variety of connection crosstalk. Standards Organization This phenomenon is called a short circuit. CAT 5e and CAT 6 cables, terminals generally have four pairs of children line. For some connections, I have seen a data connection only two pairs of children line. The other two children line for the data connection. This connection method does have a problem. When this signal is encountered on another line noise signal when the signal is transmitted on these lines, there will be crosstalk. If the USB Data Sync Charger Cable Cord For HTC EVO 4G Sprint is laid on the right, crosstalk, and abnormal signal attenuation would not have happened.

Using the correct connection method and attention to detail, the high transmission frequency should not encounter problems. Only poor-quality connections and facilities will need high transfer rate caused by network anomalies.
