A Cat6 patch lead or cable, also known as a straight-through cable, is used for connecting devices of different types, like a computer to a switch or hub. Cat6a shielded twisted pair cable has a shield in cables to prevent electromagnetic interference (EMI) or radio-frequency interference (RFI) from affecting the performance of the cable. It also prevents cable signals from interfering with surrounding cables and equipment. Properly installed Cat6a shielded cables automatically curb EMI and crosstalk, helping to ensure data integrity and high-speed performance. The Cat6a shielded cables must be grounded to work. For everything else, unshielded should be perfectly fine. Just be sure that even if you’re buying unshielded cables, you buy ones that are built to a high standard. That is cables with a solid copper core, not copper-clad aluminum, and if you want some additional rigidity in the cable (and some protection against crosstalk) get one with a spline too. For the ultimate in shielded cabling, however, you should consider the latest and greatest Ethernet cable technology: Cat8 cables. These offer the highest network performance, managing up to 40 Gbps over 100ft, or up to 10Gbps over 300ft. Unlike other categories of cables, however, they are mandated to come with foil wrappings on the individual twisted pairs, so you’re guaranteed to get a high-quality shielded cable with a Cat8 cable from Cable Matters. Alongside that foil wrapping, they also include braided shielding. That does raise costs slightly, but not significantly so.
F/FTP: A shielded cable with a foil shield around the entire cable, and foil shielding around each twisted pair. This provides effectively 100% shielding against EMI, but the foil is vulnerable to physical damage over time. The main advantage of Cat 6 cable over previous generations is its capability to support Gigabit Ethernet (up to 1000 Mbps) and higher network speeds. It has more stringent specifications for crosstalk and system noise compared to Cat 5e cable, which allows for better performance and less signal degradation over longer distances. Applications The choice of shielded vs. unshielded cables is at least relatively straightforward: if you are concerned about the sanctity of your data on your network, get shielded cables. If your network is in a busy location with lots of other electronic devices, particularly heavy machinery and air conditioning units, then get shielded cables. If aren’t sure whether you need shielded cables or not, just play it safe and get shielded cables. SF/FTP: A shielded cable with both a braided shield and foil shield around the cable, with foil shielding around the individual twisted pairs. This is the highest level of Ethernet shielding available, with strong external EMI protections, warding against crosstalk, and a durable braided shield to help prevent future damage to the shielding.This should make the shielded vs. unshielded cables debate an easy one to solve. If you need EMI protections, you’re going to need shielded cables. However, if you can get away with it, you’ll save money, and installation headaches by going with unshielded cables instead. When choosing Ethernet cables for your home or business network, evaluate the environment & cost to select the appropriate shielded or unshielded cables that meet your network needs.
S/UTP: A shielded cable that uses a braid, or screen, around the entire cable. This doesn’t provide as much protection as foil shielding, but it is more durable. It’s also more traditional, and quite commonly found in older shielding cables. It can add considerable extra weight to the cable, though, which can make managing it a little more complicated.

Do I need STP Cat6a cable? If one or more of the following common scenarios applies, then the shielded cable is suggested: S/FTP: A shielded cable with a braided shield around the entire cable, and foil shielding around each twisted pair. This is the most common form of shielded cable because it provides nearly 100% protection while remaining strong and flexible. The cost problem is compounded by requiring additional shielded hardware at the ends of the cables to fully protect against EMI, and some networks will require additional grounding wires to provide full protection. Whatever the source of the EMI, though, STP cables are designed to protect against it far better than unshielded cables. They achieve that through various methods of construction which provide better levels of protection. At the core of the cabling, all unshielded and shielded cables are built with twisted pairs of copper wiring. Those pairs are twinned deliberately to reduce crosstalk between them and the other pairs, but shielded cables go much further than that.
Unshielded cables, on the other hand, don’t have any of that. They’re more affordable, are easier to install, and are much lighter to work with. That makes them easier to carry around, and in extreme bulk, makes them cheaper to ship between locations, too. Shielded cables can have shielding for each of the twisted pairs individually, shielding for all of the cables together, or both. Typically this comes in the form of foil or braided shielding, and there are lettered designations for each type. In addition, shielded cable, while not excessively heavy, can become weighty if you are running a lot of cables in one area. Heavy cabling run above a ceiling or behind a wall has been known to cause structural damage. It might seem that shielded cables are probably the best way to go, especially if data integrity is incredibly important to your network. And to some extent, that’s true, but there are some other factors worth considering that could make your choice of shielded vs. unshielded cables a little harder to make. SF/UTP: A shielded cable that has a braided shield around a foil shield, both of which protect the cable as a whole, while the individual twisted pairs are still unshielded. This is an effective combination of shielding for external EMI, which does less to protect against crosstalk between the internal wires.You may already have decided that you need Category 6 Cable. Buying Cat6 cable means you will be able to receive up to 1 Gbps Ethernet transmission. Plus, Cat6 is essential for 1000 Base-T style networks. So far, so good.
