What is the difference between optical fiber jumper and copper wire

What is the difference between optical fiber jumper and copper wire ？ During generic cabling , The difference between optical fiber jumper and copper wire in delay , Today we will introduce in detail , Friends in need can refer to

Generic cabling , Optical fiber has replaced copper wire as the mainstream connection equipment . Many people think it is because the delay of optical fiber line is shorter than that of copper wire , What is the difference in delay between fiber patch cords and copper wires ？ Let's take a look at the detailed tutorial .

1、 What is delay ？

The delay is literally , It just slows down , This is due to speed limitations in the physical system , The waiting time of a signal from one place to another , It is divided into Network delay 、 Audio delay 、 Wan latency Etc . A key factor affecting the delay is the signal speed of the transmission medium , Optical fiber and copper wire are two transmission media , Their distance and bandwidth determine when to use them .

2、 What is the delay of the fiber ？

At present, optical fiber is widely used , Let's take a look at the delay of optical fiber .

Physics knowledge , The speed of light in vacuum is 3*10 Of 8 Cubic meters / second , Under air conditions , The speed of light will be slower . therefore , When an optical signal propagates in an optical fiber link , There are five steps to wait ：

• Electrical signals are converted into optical signals to produce two ;
• An optical signal is generated through an optical fiber ; 0 Optical signals are converted into electrical signals to produce two ,

Here's the picture :

3、 How about copper wire delay ？

The signal quality of copper wire is not as good as that of optical fiber , Especially in the long-distance transmission, the signal is easy to be interrupted by the surrounding environment , The longer the distance , The more severe the attenuation . It often causes the client to lose 、 Page error 、 The user opens it slowly .

4、 The delay difference between optical fiber and copper wire is theoretically , Signals travel faster through copper wire , But in the long-distance demand , Less signal processing and repetition , The delay of optical fiber will be low , Copper wires are susceptible to external interference , Big loss , The delay is also larger . actually , We do not use delay to describe optical fiber and communication networks , Are described in terms of distance and speed , The delay varies with distance and speed . for example , stay 1.5Mbps Serial one on the link 150 Byte packets require 8ms, And in the 10Gbps I just need 1.2us, There will be less delay at high speed .

5、 Summary that is to say , The delay difference between optical fiber and copper wire is affected by speed and distance . At shorter distances , Copper wire can be selected as the transmission medium , The cost is much lower than that of optical fiber ; In long-distance transmission , Optical fiber can be selected as the transmission medium , More stable performance , at full speed （FS） Supply different lengths of optical fiber and copper wire , Meet the needs of different situations .

The above is a detailed introduction to the difference between optical fiber jumper and copper wire in delay , Hope you enjoy it
