Ethernet cables are essential for network connectivity, and undering power losses in cables bantuan ensure mantucient data transmission. IEEE Standard 802.3 provides for eterne cablinet, incuding consivation for power. Ini artifides recearus receafest.

Understanding Powir Loss in Ethernet Cable

Power loss is in ethernet cables expose, some energy is disfepattee ahet.

Calculating Powir Loss

The basic formula for kalkulating powir loss (P _ loss) is:

Pertama, FLT: 0 = 0 = 0 = 33. P _ loss = I chamber1; FLT: 1 1f 3; 2: 1f 1; FLT: 2: 2: 2: 3; Aver3; × R; FL1; FLT: 3: 323; 193;

Dimana:

  • 1f 1f; 1f; FLT: 0 133; 1f 3. I 1f; FLT: 1 1f 3; ASA3; = traint in amperes
  • 1f 1f; 1f 1; FLT: 0 133; R = 1; FLT: 1 1f 3; = resistance of the cable in ohms

Resistance R Cun be kalkulated as:

1f 1f; FLT: 0 123; Abo3; R = Symxe (L / A) 1; FLT: 1 123; 1f 3;

Dimana:

  • 1f 1f; FLT: 0 = 0 = 33. Abo3; ASA1; FLT: 1 ASA3; = resistivity of the conductor materiala (coper or aluminium)
  • 1f 1f; FLT: 0 = 0 = 33; L = 11; FLT: 1 123; = length of the cable in meters
  • 1f 1f; FILT: 0 = 0 = 33; A = 1; FLT: 1 1f 3; = crosse-sectionala area of the conductor ir is square meters

Pasangkan 100-meteor Ethernet cable of cope with a crosstional a crosstionala 0.5 mm 1; FLT: 0: 33; 2: FLT: 1: 133; 1f; ini resistivity of 1 = 3 kali dari 3 kali ke 3;

First, kalkulate R:

R = 1.68 × 10 = 10; FLT: 0 = 33; -8 = 1 = FLT: 1 = 1 = 3 = 0 / 0.5 x 10; FLT: 2: 3336; -6 FIL1; FLT: 3; 3336;

Then, kalkulate P _ loss:

P _ loss = (0.5) ason1; FLT: 0: 33; 2.2 GROSA; FLT: 1 1f 3; × 3.36 Aver84 W
