The process of learning is like a process of charging a capacitor. A person is like a capacitor. If you don't stress it, you won't be charged, but if the pressure is too high, the capacitor will be broken down.
The teacher is a capacitor, just started charging, and then discharged, and passed on his knowledge to the students without reservation. The difference is that the teacher's power can never be exhausted, and the capacitor almost completely discharges all of his energy.
Don't be an inductor when you are a capacitor. The inductor always blocks the historical trend, but it always looks pale and weak. When the current increases, hindering him, when he also impede current is reduced, but ultimately can not pull back, I grew up determined to do capacitor!
Some people's lives are like the current along the diode, almost no hindrance. Elementary schools, key junior high schools, key high schools, key universities, large enterprises, high salaries, and the beauty behind them are inexhaustible.
Some people, like the current against the diode, have a lot of difficulties and are stuck when they are not careful. Maybe there is only one way, that is, let your own voltage be infinite, puncture it. When faced with pain, you have two choices, either by pain or by stepping on the foot, even though the process itself is very pain.
Some people are triodes, able to enlarge and magnify what they have learned, and make a great contribution to society. Some people are resistance, nothing but energy.
Divide an optical jumper into two to become two optical pigtails.
The optical jumper refers to the optical connection line with the optical fiber movable connector installed at both ends of the optical fiber or optical cable. It is usually used for fiber patching or switching in distribution equipment or between optical equipment, and the length is usually no more than 10 meters.
It is a popular and common saying in the industry that when the connecting wire is an optical cable (indoor optical cable), it is called an optical fiber jumper, and when the connecting wire is an optical fiber, it is called an optical fiber jumper.
In mobile communications, coaxial cable jumpers have special product standards, while optical jumpers are different. Optical jumpers do not have special product standards. Because the attenuation of optical fibers is very small, and the length of optical jumpers is not long, the optical fiber attenuation is negligible. Therefore, the optical fiber movable connector standard is also used as the optical patch cord standard in practice. Some content of the optical fiber movable connector is different from the optical patch cord. However, in the long run, the industry has already considered the optical fiber movable connector standard That is, it is the standard for optical patch cords.
