Comprehensive cabling system in the choice of network cable is very important, in the computer network, video surveillance systems and other systems in the network cable selection is the same? When to use gigabit network cable, when to 100 megabit network cable?
Internet information and communication era, people rely on the network more and more serious, the speed of the network directly affects our daily life. Do you know that network cable is also divided into different rates? For example, hundred megabit cable, gigabit cable. So in what kind of scenarios generally use 100 megabit cable, what kind of scenarios use gigabit cable, this article will explain in detail.
How to differentiate between Gigabit and 100 Gigabit cables?
Gigabit network cable and 100 megabit network cable are generally distinguished according to the specification markings or parameters on the cable.
(1) Gigabit network cable
Generally speaking, the transmission rate of Cat6 Category 6 cable is 1000 Mbps, while the transmission rate of Cat6a Super Category 6 cable and above is more than 10 Gbps, so Cat6 Category 6 cable is called Gigabit cable.
(2)100Gbps cable
Usually the main transmission rate of Cat5e Category 5 cable is between 100 Mbps~1000Mbps, which can be used for Gigabit transmission under certain conditions, but the effect is not good, while Cat5 Category 5 cable has a main transmission rate of 100 Mbps, so Cat5e Category 5 cable and Cat5 Category 5 cable are called 100 Gigabit cable.
But in fact we need to know, the network cable specifications to ensure that the electrical transmission performance, rather than network speed, the actual network speed is not only related to the cable, but also with the terminal equipment has a great relationship.
How to choose between Gigabit and 100 Gigabit cables
Gigabit Ethernet cables and 100Gb Ethernet cables can play different roles for different network transmission needs. When the required transmission rate is mainly 1000 Mbps, then use Gigabit cable; when the maximum required transmission rate is not more than 1000 Mbps, then use 100 Gigabit cable. The following are examples of Gigabit cables and 100Gbps cables:
(1) Cat6 Category 6 Gigabit Network Cable - Horizontal Cabling Solution
When horizontal cabling of Gigabit network is required, Cat6 Category 6 Unshielded (UTP) Ethernet Gigabit cable can be chosen, which is designed with card groove protection and RJ45 connector to transmit Gigabit network stably.
(2) Cat5e Ultra Category 5 100 Gigabit Network Cable - Ethernet Fiber Optic Transceiver Cabling Solution
Cat5e Category 5 Ultra 5 Unshielded (UTP) with Card Gutter 100 Gigabit Ethernet cable is specialized for connecting Ethernet media transceivers and Ethernet switches.
Can Gigabit Ethernet cables and 100Gb Ethernet cables be used together?
In the 100 Gigabit network, Cat5 Category 5 100 Gigabit cable in the process of transmitting network signals, only 4 cores, while in the Gigabit network, Cat6 Category 6 cable in the process of transmitting network signals using 8 cores, Cat5 Category 5 cable's four cores can not be achieved at the same time as the Gigabit network transmission of transmitting and receiving, that is, four cores can only be realized in the Gigabit network to receive data or send data, which can not be done at the same time, but the network port specifications are the same, so the Cat5 Category 5 cable and Cat6 Category 6 Gigabit cable can not be completely common. At the same time, but the specifications of the network port are the same, so Cat5 Category 5 100 Gigabit Ethernet cable and Cat6 Category 6 Gigabit Ethernet cable can not be completely common.
Cat5 Category 5 cable has not gradually no longer be used, today's 100 megabit cable mainly refers to Cat5e Category 5 cable, Cat5e Category 5 cable and Cat6 Category 6 cable are 8-core twisted-pair cable, so you can use Cat6 Category 6 cable for 100 megabits of transmission, you can also use Cat5e Category 5 cable for gigabit transmission under certain conditions, they can be common.
However, it is worth noting that the crystal head of Gigabit Ethernet cable and the crystal head of 100 Gigabit Ethernet cable can not be used universally, they have different sizes of copper cores, so the size of their internal holes are also different.
Summarize
In fact, from the above we can see that Gigabit Ethernet cable and 100 Gigabit Ethernet cable is a more rough division, really want to sub-divide or need to Cat5, Cat5e, Cat6, Cat6a, etc. to divide, and then based on the parameters to analyze and buy.
