Category 8.1 and 8.2If your internet subscription exceeds 100 Mbp, you shouldn't use a CAT 5 cable to connect your modem and router, according to the chart. Use a CAT 5e or newer, at the absolute least, for plans of 200 Mbp and above.
The same RJ45 connector is used by all Cat5, Cat5e, Cat6, Cat6a, Cat7, and Cat7a cables.
a 1000 Mbps connectionIn contrast to Cat5e Ethernet cable, which supports networks up to 1 gigabit (1000 megabits per second), Cat5 supports networks up to 100 megabits per second. Cat5e, on the other hand, is available in shielded varieties and does better at suppressing noise. Observe: 100–250 MHz, 1 GB/100 m.
You should use a hielded RJ45 connector if the cable is shielded. Conversely, use a hielded RJ45 connector if the cable is not shielded. Using a shielded connector on an unprotected cable will have no effect, even if the fitment was good from the start (which is unlikely).
In industrial, engineering, or manufacturing environments where a high level of electrical power is present and data and power transfer is susceptible to electronic interference, shielded cable reduces and insulates the transfer of data or power from "electrical noise" or ambient electromagnetic interference (EMI).
It is best to ground the hield at both ends of the cable when wiring shielded cable for screening. In the past, it was customary to ground only the source end of the shield in order to prevent ground loops. Practice grounding at both ends, but keep in mind that ground loops are a possibility.
Any shielded cable needs to be grounded appropriately. These call for a connector and tools capable of at least adequately grounding the shield on both ends. A difficulty with improperly grounded, hielded wire is that the hield will make the issue that it was intended to solve worse.

The cable shield is typically grounded to the patch panel through the connector. After that, I hooked the panel to the rack, which I then grounded to the TC's telecommunication grounding bar. Avoid grounding the cable shield at the outlet in the work area.
The cable's shield provides protection against electromagnetic interference. It stops disruptive signals from the cable's inlet from traveling to its outlet and disrupting other cables or even electrical equipment. Additionally, the shield makes sure that outside interference stays outside of the cable's insulation.
