About this deal
That’s because it’s less prone to interference and the length limit of the Ethernet does not apply to the fiber optics cable which can go for miles. An “F” followed by “TP” would mean that there is a layer of foil over the cable itself, but the twisted pairs (TP) of wires inside are individually unshielded. When you start looking at specific Ethernet cables to match your needs, you’ll quickly notice that they’re divided by “Cat” numbers.
Even simple bends around a corner or over the edge of a desktop can cause the copper wires inside to break over time. Compared with the traditional round Ethernet cable, the flat Ethernet cable is more suitable for use in homes, offices, cafes and other places. The cable’s 100% base OFC conductors are wrapped in an HDPE jacket and a second aluminum foil shielding layer.If you have a slower connection — perhaps 10 or 20 megabits per second — you’re good with anything Cat 5 or newer (more on this below). Some designs also wrap all shielded wires like a burrito using an added layer of braided material or foil. In the US, the NFPA's National Electrical Code (NEC) guidelines requires CMP or CMR cabling for plenum or risers and compliance may be a contractual or legal requirement.
The big takeaway from OFC is that you want a cable that uses pure copper, and OFC is close to that level.As a result, our cables are known for not just meeting the market standards but also exceeding them. For a time, this unshielded twisted pair (UTP) cable was the most common form of wiring for voice telephone systems in homes and offices. Ethernet cables with thin wires are maybe easier to install, but also limit the maximum length and are more prone to damage. Yet its overall design and high performance make it ideal for local area network gaming, streaming media from a local server, and moving files to and from a network-attached storage device. In fact, it’s worth remembering that most broadband routers still don’t deliver 1Gbps Wi-Fi, so a Cat5e cable still isn’t a bottleneck.
