Patch cords (patch cords) are called electrical or fiber optic cables that allow you to connect or connect electrical devices. These products are most widely used in the field of design and creation of local area networks. To connect switches, connect workstations to network equipment, patch cord 5e manufactured by industrial or artisanal methods is often used here. The course also fiber optic patch cords.
Patch cord - what is it? How does it work?
To connect disparate network components, you need to use special cables. So, to connect a PC to a DSL router or switch, you will need to prepare a network patch cord. What it is? This is a segment of shielded or unshielded UTP cable with a length of 1.5 m or more, with RJ-45 connectors fixed on both sides of the cable with a crimping tool.
Such cables can be used to connect virtually any component of a network environment. An exception is devices that only support fiber optic interfaces. In some local networks, there are still switches for devices working through a coaxial cable. To date, they have almost disappeared.

The CAT 6 cable has additional protection and prevents collisions in the network due to electrical interference and other factors. It is certified for use on Gigabit Ethernet networks. The main reason why category 6 wire is not ubiquitous is the high price. Yes, and most network tasks can be completely solved using a CAT 5 or CAT 5e cable.Gigabit Ethernet Support, UTP Cable Quality Issue

In general, one of the main elements of any modern computer network is patch cord. What does this mean in practice? The fact that the stable operation of the entire network will largely depend on the quality of this product. For example, poor protection against electrical interference can lead to a large number of errors and a decrease in the data transfer rate. This cannot be allowed. You need to carefully monitor the quality of the UTP cables that are used in the local network.Fundamental differences of patch cords of categories 5 and 6

This product is a regular twisted pair cable segment with an RJ-45 connector at each end. Using it, the wire is inserted into the corresponding connector on the switch or on the network card of the computer. Data is transmitted in the frequency range up to 100 MHz. Such patch cords are recommended for use in structured cabling systems (SCS). So in a scientific way are called local computer networks. Twisted pairs of categories 5 and 5e do not have a layer of additional protection, therefore, can only be operated in closed rooms.-? , ? , 0,52 . . , . UTP , .

Why use a cross patch cord? What does it give? Previously, these cables were used to connect computers to each other. Today, this decision is largely outdated. There is no longer any need for cross-connect options for connecting individual PCs without switching equipment. Modern network cards have learned to independently determine which cores are used to transmit signals, and which are being received. Therefore, the tasks that this network equipment should solve will be equally well performed with any type of cable.
