Do you know the difference between a fiber optic jumper and a copper cable?
In the general wiring, the selection of optical fiber has replaced copper wire to become the main connection equipment.Many people think fiber optic lines have shorter delays than copper cable, so what's the difference between fiber optic jumpers and copper cable?
1,How about fiber optic delay?
Since there are many applications of optical fiber, let's first look at optical fiber delay.
Physics, the speed of light in a vacuum is 3 times 10 to the 8th meters per second, and it slows down in air.So when an optical signal travels down an optical fiber link, it waits for five steps: the electrical signal is converted into the two signals that produce the optical signal;An optical signal is generated by an optical fiber;The light signal becomes an electrical signal producing two.
2,How about copper cable delay?
The signal quality of copper wire is not as good as optical fiber, especially in the long distance transmission process, the signal is easy to be interrupted by the surrounding environment.The longer the distance, the worse the attenuation.The client is often lost, the page is wrong, and the user is slow to open.
3,In theory, the delay difference between the fiber and the copper wire travels faster in the copper wire.However, under the requirement of long distance, less signal processing and repeated processing are required, fiber optic delay is low, copper wire is susceptible to external interference, loss and delay is large.In fact, we do not need delay to describe optical fibers and networks, they are both described in terms of distance and speed, and different distances and speeds have different delays.For example, it takes 8ms to serialize 150-byte packets over a 1.5Mbps link, whereas 10Gbps is only 1.2us, and the latency at high speeds is lower.
4,The delay difference between optical fiber and copper wire is affected by speed and distance.Short distance can choose copper wire as the transmission medium, the cost is far lower than optical fiber;For long distance transmission, optical fiber can be selected as the transmission medium, which has more stable performance.Fast (FS) provides different lengths of optical fibers and copper wires to meet the needs of different conditions.
Generally, the transmission distance of copper wire is not more than 100m, while the transmission distance of optical fiber can be up to 100km (single-mode optical fiber), which is much greater than the transmission distance of copper wire.
The maximum transmission rate of copper wire can reach 40Gbps(such as class 8 network cable, DAC passive copper cable), and the maximum transmission rate can reach 100Gbps(such as OM4 optical fiber jumper), far exceeding that of copper wire.
The operations such as making a copper connector and connecting a device port are simple, but the operations such as cutting and welding an optical fiber and connecting a device are complex and demanding.
8,Price and cost
When the length of optical fiber and copper wire is the same, the price of optical fiber is generally 5 to 6 times that of copper wire. The price of optical fiber insertion devices (such as optical fiber couplers) is also much higher than that of copper wire. Therefore, in terms of price cost, the price of optical fiber is much higher than that of copper wire.
Twisted pair in computer LAN can be divided into two categories: unshielded twisted pair (UTP) and shielded twisted pair (STP). The STP is wrapped by a metal material to reduce radiation and prevent information from being eavesdropped. It also has a high data transmission rate, but it is expensive and complicated to install.UTP does not have metal shielding material, only one layer of insulating rubber wrap, the price is relatively cheap, flexible network.In addition to some special occasions (such as the electromagnetic radiation is serious, the transmission quality requirements are higher) in the wiring use of STP, we generally use UTP.
