Which twisted-pair category can support 10gig ethernet?
The category 6a cable is used in order to support the 10 gig ethernet. Generally, we have different types of networking cables that are present to connect to the different types of devices. The most common cables that are present in the networking are coaxial cables, twisted pair cables, optical cables, parallel and serial cables.
All these networking cables are used for the network topology, hardware, software, and network size. Networking keyboards, connectors, and their specifications belong to the physical layer or layer one of the OSI model. Now let us discuss the twisted pair cable specifically along with the shielded twisted pair and the unshielded twisted pair. Normally, shielded twisted pair(STP) twists appear on the shoulder, the twists appear on the solid cable vs the stranded cable. And let us discuss a brief introduction to the category rated cables.
Most of the modern network keyboards are made from eight wires which are twisted in pairs. And these pairs are twisted to eliminate the cross talk and helps to improve the data transmission performance. These twisted pairs are the four different color-coded that insulated the copper wire in orange, blue, green, brown. In each wire has a solid color and the other one is predominantly white with the color stripe.
We have more wire pair twists per foot which mean we have more resistance to the crosswalk. This also has a higher quality so that these are more expensive. The twists per meter or afoot, we call it the twist ratio. If we have the higher twist ratio, then we have fewer crosswalks but it has the greater attenuation. We need to maintain a balance between minimizing crosswalks and reducing attenuation. These twisted pair cables then can be shielded or can be unshielded. Let us learn the shielded twisted pair in detail.
The below figure represents the structure of the shielded twisted pair. The outer layer, we call it the plastic and the shield. The second layer that is present we call the braided shielding. This is a type of metallic substance that protects the cable from electromagnetic interference or by the EMI. We also have an aluminum foil shielding underneath the braided shielding.
In the figure, the foil shielding wraps an individual set of wires. Some may also contain foil shielding for all the wires that are present while some of the cables don’t have any foil shielding Shielded twisted pair. The shielded twisted pair that consists of the foil shielding have the individual or overall is called the fully shielded twisted pair (FTP).
The individual fielding helps to prevent the EMI and the cross talk from the neighboring wires. Each copper conduct wire is also covered by the plastic insulator. The STP is recommended where EMI is strong. These shielded twisted pairs are mostly used for horizontal cabling. When we compare the STP with the UTP. It has only fewer layers than the UTP. Plastic shield and wire insulators are the two layers of the UTP.
