Spot supply: 48V0.5A, 24V1A, 18V1A, 15V1A, 12V1A optional
U. rules: POE port = power supply (45 pin 78 pin cathode) + data (1236 feet)
LAN port = data (1236 pins)
POE port: connect the bridge AP CPE equipment WAN interface
LAN port: connect to the router switch or directly connect to the computer host network interface
The use of distance: the quality of the network cable, power supply voltage and the ability to adapt to the voltage of the electrical equipment. Generally speaking, the copper wire and the 12V power supply under the condition that the distance is 10-30 meters. The higher the voltage, the better the quality of the network, the more effective power supply distance.
For general networks is only to 1236 transmission data (Web data), 4578 idle, so many in the production of cable businesses in the production of cable are 4 is wire non pure copper wire, such as this line with POE power supply will lead to large power supply voltage drop.
II because the very fine wire, mass residuals not neat, there are individual copper clad aluminum wire, wire resistance is very large, loss is severe. The actual test results: general cable at the time of 12V 10 meter lower V. So the voltage of about 12V and a distance of 20 meters
How to distinguish the quality of the network:
1. Material from the husks: hand thrust about cable with skin, soft like hollow point is a kind of relatively poor quality, the better the feels quite full.
2 to determine the cable tension: if the elastic skin is very large, is actually not very good, hard pull easily lead to inner core snapped.
3 depth copper core see ingredients: with scissors or wire pliers cut a short section of the line to see if the wire core appearance is copper, but the inner core is silver steel core, it is relatively poor, 1 dollars a meter. If inside the outside are yellow copper, that is relatively good, 2-3 yuan a meter.
In addition, but also look at the thickness of the copper core, some materials, copper core is relatively small, and some of the more rough.
Ultra five types of cable to see more than a few on the line. 6 categories, 7 categories with shielding function, but also to see how the shielding layer of the network. Some of the 8 cable is wrapped in the outer sheath, and there is a network of each pair of lines are wrapped with a shield, which is the difference.
Cable equipment to do the line standards:
Through 568B, mainline, straight line, 568B standard: both ends of the line order, from left to right line sequence is: orange and white. Orange. Green and white. Blue. Blue and white. Green. White and brown. Brown)
