標準的POE交換機傳輸和供電距離

眾所周知，以太網標準規定傳輸距離最遠是100米，超過100米可能會發生數據延遲、丟包等現象，因為信號在雙絞線中傳輸時，彼此之間相互干擾，還會受到外界電磁波的干擾，同時由於導線之間產生寄生電容和寄生電感的原因導致信號衰減和畸變，距離過長後累積的信號衰減將不能保證信號穩定地傳輸欢迎www.xbaixing.com。

事實上，網線也能超過100米的有效傳輸，質量好的能達到120米左右，也就是無氧銅超五類網線，或以上網線類型x_b_a_i_x_i_n_g_c_o_m。這種網線能降低自身干擾，也避免串聯和外界帶來的干擾小百姓网www.xbaixing.com。

因此，POE交換機供電傳輸距離，說白了就是取決於網線的質量x+b+a+i+x+i+n+g+c+o+m。質量好的網線，其電力信號傳輸可以超過100米，甚至可達到150米来自www.xbaixing.com。

Standard POE switch transmission and power supply distance

As we all know, the Ethernet standard stipulates that the transmission distance is up to 100 meters. If it exceeds 100 meters, data delay and packet loss may occur. Because the signals are transmitted in the twisted pair, they interfere with each other and are also subject to external electromagnetic waves. Interference, and signal attenuation and distortion due to parasitic capacitance and parasitic inductance between the wires, the signal attenuation accumulated after the distance is too long will not guarantee the signal transmission.

In fact, the network cable can also transmit more than 100 meters, and the good quality can reach 120 meters, that is, the oxygen-free copper super five network cable, or the type of the Internet cable. This kind of network cable can reduce its own interference and avoid the interference caused by the series and the outside world.

Therefore, the transmission distance of the POE switch power supply is simply determined by the quality of the network cable. A good quality network cable can transmit more than 100 meters or even 150 meters.
