How fast is gb ethernet

Visual data, as you may know, is extremely data-heavy. So among the best uses for gigabit ethernet is to ensure that transferring or streaming video data is as smooth and frame-rate-perfect as possible.

Even better, a gigabit connection allows you to split off an incredibly high-speed internet into multiple tasks and devices without slowing any one device or streaming session down. Gigabit ethernet is also highly valuable if you do an extensive amount of file transfers inside your internal LAN network of computers. For businesses and private tech owners alike, gigabit offers serious speed capabilities both as a unified transfer channel and split into multiple ethernet sources within the network.

Now for how Gigabit ethernet actually works inside a normal Cat5e or Cat6a cable. In addition, you already know that Cat5e and Cat6a cable each have 8 wires in 4 pairs. Keep that in mind as we move forward.

PoE, for a quick refresher, stands for Power over Ethernet. It uses those same pairs of wires in Cat5e and Cat6a cable to transfer small amounts of electricity to low-powered devices like web cameras, wireless access points, LED lights, and VOIP phones. In other words, it saves you the trouble and expense of rigging up a second powered cable for a device when the small amount of electrical transfer through a Cat6a will do. PoE is powered by installing a PoE injector into the data line which simply pushes electricity down the wires in addition to the data that is already flowing.

Nifty, right? This leaves the other two spare pairs of wires to be used for PoE power. Data travels down one path, power travels down the other. Back when PoE was first introduced, this was the safest way to do things. But internet technology has come a long way since then.

And thankfully so. Whoever has lived long enough to experience a 56k modem would just as soon face a zombie apocalypse before going back to dial-up internet speeds. Which begs the question, how the heck can Gigabit Ethernet — which uses all four pairs of wires — also power PoE devices?

This raw capacity is that of the actual link itself. However, note that this is still not an accurate representation of what your customer can expect in the real world.

Other factors will influence the real-world throughput. Note that for Wireless links such as Microwave, Radio, Millimeter Wave or Free Space Optics, the Airside Interface often uses different coding and modulation than the network side interface.

This difference is often due to limitations in the amount of RF spectrum available for example, a 40MHz, 56MHz, 60MHz, 80MHz or even MHz channel from the regulatory body and channel planning, the modulation used for example, up to QAM or QAM which affects both transmit power and receiver sensitivity, aggregation features such as MIMO or XPIC, and especially for longer links, the corresponding Link Budget between the two ends which includes the Antenna Gain at both sides, plus any losses caused by transmission waveguides, connectors, plus atmospheric fade effects.

Note that only some wireless technologies such as Free Space Optics FSO are capable of fully transparent transmission using the exact same modulation used on Fibre Optic networks, so the full 1.
