Here we can see, “what kind of ethernet cable do i need”

A key component in wired home networks is — wires! More correctly, cables. Twisted-pair coaxial cable is the commonest sort of home network wiring used today (and for the foreseeable future). Twisted-pair Ethernet cables are wont to connect:

  • DSL/cable routers or modems to computers
  • DSL/cable routers or modems to wireless access points
  • DSL/cable routers or modems to hubs or switches
  • Computers to hubs or switches
  • Computers to other computers
  • Other devices (such as network printers) to computers, hubs, or switches

What’s the difference between a wire and a cable? A wire may be a single conductor (typically copper) which will be solid or stranded. On the other hand, two or more insulated wires grouped during a sleeve or jacket (typically plastic) form a cable. (If each wire isn’t insulated, then it’s technically still a wire.)

Twisted pairs and RJ-45 connectors

Twisted-pair Ethernet cables contain eight copper insulated wires during a plastic sleeve. Two wires are twisted together during a pair for the completion of 4 pairs, and then the four pairs are twisted together to make the cable. The twists and pairs affect certain performance characteristics of the cable, like crosstalk, attenuation, and electromagnetic interference (EMI).

Crosstalk occurs when an electrical signal transmitted over one wire negatively affects the electrical signal transmitted over another wire. Attenuation is that the gradual loss of intensity of an electrical signal because it travels over the wire. EMI is noise (unwanted electrical signals) generated between the wires by the varied electrical signals transmitted.

A clear plastic jack, referred to as an RJ-45 connector, is attached to both ends of the twisted-pair coaxial cable. An RJ-45 connector looks almost like a phone jack (which is understood as an RJ-11 connector).

Categories of twisted-pair cables

There are several categories of twisted-pair cabling, but only three are commonly used for Ethernet networks: Category 5 (Cat5), Category 5e (Cat5e, or Cat5 Enhanced), and Category 6 (Cat6). The performance characteristics of Cat5, Cat5e, and Cat6 are as follows:

  • Cat5: Supports accelerates to 100 Mbps at 100 MHz, with a maximum cable of 328 feet (100 meters).
  • Cat 5e: Supports accelerates to 1,000 Mbps (or 1 Gbps) at 100 MHz, with a maximum cable of 328 feet (100 meters).
  • Cat6: Supports accelerates to 1,000 Mbps (or 1 Gbps) at 250 MHz, with a maximum cable of 295 feet (90 meters).

Unshielded versus shielded cables

Twisted-pair Ethernet cabling also can be unshielded (common) or shielded (not so common). Unshielded twisted-pair (UTP) cabling is employed in both large enterprise networks and little home networks. In addition, it’s relatively inexpensive and far more flexible than shielded twisted-pair (STP) cabling.

STP cabling is costlier and less pliable than UTP cabling. As a result, it’s utilized in industrial and other noisy environments susceptible to high electromagnetic interference (EMI). The individual pairs of wires in STP cables are wrapped in foil or another metal shielding, and an outer metal shielding can also cover the whole group of twisted pairs (beneath the outer sleeve).

Straight-through versus crossover cables

In most cases, you’ll use straight-through twisted-pair Ethernet cables to attach the devices to your network. However, crossover cables are sometimes required to connect two computers directly (if one among them features a network adapter that’s quite a couple of years old), to attach rock bottom (or old) network switches that don’t have an uplink port or to attach some sorts of specialized network devices.

Length and color of networking cables

When choosing cables for your network, you furthermore may get to consider length and color:

  • Length: Twisted-pair Ethernet cables are standard lengths like 3, 5, 7, and 10 feet. Longer lengths are available, and you’ll even have custom cable lengths made. the space between your various network devices and your network switch or router will determine the length you would like. Don’t forget to incorporate enough length to run cables along walls, under rugs, and around corners as necessary.
  • Color: Twisted-pair Ethernet cables are available in all kinds of colors. These decisions are often based purely on your tastes and preference. Blue is probably the foremost common, but you would possibly also consider white, gray, or another color that doesn’t clash together with your walls and carpet. Finally, you’ll want to stay with one color for all the cables on your network.

User Questions:

1.Which is the best flat or round Ethernet cable?

Due to these reasons, flat ethernet cables have less durability and high maintenance costs than round ones. Flat wires are less sustainable than round ones, and that they don’t have any protective filler around them. … Hence, it’s better to settle on the present flat coaxial cable than round networking.

2.Is it bad to bend an ethernet cable?

Never bend a coaxial cable with a radius, but one inch—the diameter of 1 / 4 . a pointy bend or a kink will reduce the cable’s throughput. Also, never run patch cords along the ground where they will be stepped on. … Remember the quarter rule about bending cables.

3.Can a damaged coaxial cable hamper the internet?

Yes. Ethernet cables are transmission lines. Therefore, damaged or otherwise out-of-spec ethernet cables can allow signals outside to interfere with the intended balanced signals on the cable, potentially destroying packets.
