In high-speed Ethernet-based computer networks of 1 Gbps or more between directly connected servers, switches, and computer networks, a Category 7 cable (Cat 7 cable) is a shielded twisted pair cable.

Computer networks that can send data at speeds of one Gbps, 1000 Mbps, or more typically employ Cat 6 cables. The following traits apply: consists of four sets of copper wires, each of which is used in data transmission.

CategoryTwisted-pair copper cable, which is used to transport data in network applications, comes in a variety of forms and is frequently referred to as an ethernet, LAN, and/or patch cable. The cable's grade and capabilities are indicated by the number after the prefix [Cat," which stands for Category.

10/100 MbpsCAT5, CAT5e, and CAT6.The cable's capacity is indicated by its number designation: Cat 5 is limited to 10/100 Mbps speeds with a bandwidth of up to 100 MHz, Cat 5e to 1000 Mbps speeds, and Cat 6 to 10 gigabits for a bandwidth of up to 250 MHz.

The Primary Benefits of Fiber over Copper (UTP)Broader Spectrum and Quicker Speed: Fiber optic cable can provide much higher speeds and incredibly high bandwidth. The biggest benefit of optical fiber cable is the sheer volume of data that can be transferred per element.

Benefits of the UTP include:It is an unshielded cable from another network medium that is less expensive and more affordable.
It is intended to lessen EMI, RFI, and crosstalk.
Because of its compact size, installing the UTP is simpler.
It is especially effective for local network connections, such as those at home and in small businesses.

While CAT5e is required for networks with speeds of 100 Mbps or more, CAT3 will operate just fine for networks with speeds of the now-almost-extinct 10 Mbps. CAT3, CAT4, and CAT5 cables are actually made of four pairs of twisted copper wires, and because CAT5 has more twists per inch than CAT3 it can travel farther and faster.

There are two types of Ethernet cables: UTP and STP. UTP stands for Unshielded Twisted Pair while STP is for Shielded Twisted Pair. Because STP is protected and less likely to interfere with other cables, it should be preferred. UTP can be utilized, however since it offers no protection and is less expensive, it is better used indoors.

This is because an Ethernet connection from the same router is almost always faster than a Wi-Fi connection. It's true that radio waves move quite quickly. However, using an Ethernet cable allows data to be sent and received by your devices extremely instantly. This is especially valid if your connection is fiber-optic.

o why 100m? It was related to the electrical interface and the fundamental qualities listed in the standard. One of the concepts behind switched pair wiring was to use existing cabling, and a maximum length of 100 meters was set once parameters like attenuation, crosstalk, etc. were determined.
