The commonly used formula for integrated wiring RJ-45 head demand: m=n*4+n*4*15% m: indicates the total demand of RJ-45 connector n: indicates the total amount of information points n*4*15% : indicates the demand for the surplus information module left: m=n+n*3% m: indicates the total demand of the information module n: indicates the total amount of information points n*3%: indicates the amount of surplus per floor Quantity: C=[0.55*(L+S)+6]*n L: Distance from the most information point on the floor from the management room S: Distance from the nearest information point of the floor from the management room n: Total number of information points on the floor 0.55: Standby factor 6: Termination tolerance When selecting the slot, the cross-sectional area of ​​the slot = horizontal cable area × 3 1 (the longest line spacing + the shortest line spacing) / 2 = average (average +5 meters) X points = total length total length / 305 (standard per box of meters) + 2 boxes = total number of boxes + the number can also be set by themselves, the first time, would rather prepare more points, do not afterwards 2 Service requires a pair of 4 pairs of unshielded twisted pair
Plastic Package Diode.Among the electronic components, a device having two electrodes allows only the current to flow in a single direction, and many uses apply its rectification function. The Varicap Diode is used as an electronic adjustable capacitor. Most of the diodes have a current directionality that we often call the "Rectifying" function. The most common function of a diode is to allow only current to pass in a single direction (referred to as forward bias) and block in the reverse direction (referred to as reverse bias). Therefore, the diode can be thought of as an electronic version of the check valve.
