Abstract

A method of extending the usable length of a power-over-ethernet cable includes the steps of providing twisted pairs of wires with the conductor of each wire being a 20 AWG or 22 AWG conductor and terminating the cable at an RJ-45 style connector. The connector for the 20 AWG conductors has an insert therein with holes that can accommodate 20 AWG conductors. FEP, PVC or PP insulation may surround each conductor.

Claims

1. A method of extending the usable length of a power-over-ethernet cable comprising the steps of providing the cable with four twisted pairs of wires and no other wires, each wire having a 20 AWG conductor, and terminating the cable in an RJ-45 style connector having an insert therein with holes in it sized to accommodate 20 AWG conductors.

2. The method of claim 1 further comprising the step of providing a layer of insulation around each conductor wherein the insulation is made of a material selected from the group of fluorinated ethylene propylene, polypropylene or high density polyethylene.

3. A method of extending the usable length of power-over-ethernet cable comprising the steps of providing the cable with four twisted pairs of wires and no other wires, each wire having a 22 AWG conductor, and terminating the cable in an RJ-45 style connector.

4. The method of claim 3 wherein the step of providing the cable with four twisted pairs of wires is further characterized by providing a cable lay length less than or equal to about 4.724″

.

5. The method of claim 3 wherein the step of providing the cable with four twisted pairs of wires is further characterized by providing a first pair with a lay length of about 0.5460 inches, a second pair with a lay length of about 0.8996 inches, a third pair with a lay length of about 0.6929 inches and a fourth pair with a lay length of about 0.8047 inches.

6. The method of claim 5 wherein the step of providing the cable with four twisted pairs of wires is further characterized by providing the four pairs cabling lay length of about 3.9370 inches.
