Ethernet Cable secret of high speed internet revealed..!!

In matters of speed and stability goes on the network nothing about Ethernet cable. With the latest generation of Switches and Network Adapters are even up to 10 gigabits per second possible.

WLAN and Powerline have clear the nose if it is about comfort. But the focus is on speed in the home or company network; Ethernet cables are still unbeaten. This applies even more since the former only affordable for professionals and businesses Gigabit networks very cheap price regions have achieved: as network distributors required "switches" are available in the Gigabit Class with eight ports ("ports") already from 33 USD and Gigabit-compatible network sockets bring many notebooks, PCs, Game consoles, set-top boxes and others Network devices from the factory with.

An advantage of the Ethernet technology is also that faster switches are backward compatible: used on a port of a gigabit Switches connected about a printer, the only supports 100 Mbps, the switch hangs up this port the slower pace.

On request, it is even faster: already since 2007 Ethernet is standardized with 10 GB/s. As before, the gigabit technology also achieved so far only used in larger companies and data centers network technology gradually price regions, and they make interesting even for smaller companies and ambitious private users.

High-speed networks are still relatively expensive

Although it costs an eight-port switch on all its Ports 10 GB/s supported, still at least 449 USD. Also, the fast networks make higher demands on the quality of the network cable. Next must for the high Data rate compatible network cards or adapters be purchased separately and cost at least 137 USD, sometimes much more. But for specific Applications can make this investment useful be (see "Ethernet Cable speed infograph").

Also, in the first step, only targeted individual devices with 10 gigabit / s are connected - about a NAS (central storage system) or single high-performance computer. For such solutions there are switches with mixed port equipment from about 280 USD. Especially for networks with many connected Computers can also make sense, but the so-called backbone the connection between two switches in different rooms at 10 GB/s high equip because that increases the overall speed in the network and thus the effective Data rate of each connected network client.

An interesting interim solution is provided by D-Link, Netgear, and other network equipment manufacturers: Support your "multi-gigabit" solutions also the intermediate stages 2.5 and 5 Gigabit / s. On the one hand, this takes into account the fact that some PCs or game consoles only have network connections with these Own data rates. On the other hand, these speeds can also be used with low cable qualities.

One should consider, however, interested parties: how even with gigabit networks is actually between network devices achievable data rate is significantly lower in practice - typically around 400 up to 600 Mbit / s at gigabit and about ten times Value at 10 Gigabit Ethernet. For 2.5 and 5 GB/s, the same applies. In NAS systems plays to the read/write speed of the built-in Storage media matter. But much faster as the previous home networking technology is the new Network class in any case.



10 Gigabit and also multi-gigabit Switches are relatively expensive. In virtually every network it will, however, give multiple devices, which still with maximum 1 GB/s are connected. Instead of costly high-speed, It is recommended to hang ports itself, using a gigabit switch Uplink port to the 10 Gbit Switch to dock and there all slower network devices to connect (see figure below). Who on maximum performance Value sets, chooses for it a Gigabit switch with a 10 Gbps uplink port - this avoids bottleneck effects on the uplink connection.


In the case of several rooms be networked by Ethernet cable, pierced hardly avoid walls. The one used for this Drill bit must be at least 2 millimeters more diameter have as the plug of the to be performed network cable - recommend in practice an 18 or 20-millimeter Drill bit and one accordingly strong drill. When routing the cable, tape your network or SFP-plus connector with tape or tape to prevent gypsum or dust from entering.


For home networks, it may be sound like Overkill: But for Uplink connections is a fiber optic cable one exciting alternative because many 10 Gigabit Switches have for it "SFP +" slots (Small Form-factor Pluggable Plus). Suitable modules for copper Cabling (10 Gigabit Ethernet) are much more expensive than for the same Speed designed Fiber-optic lines. On 10 Gigabit fiber cable with two permanently installed SFP-plus modules and 20 meters in length it already starting from about 101 USD, the Copper variant costs several 112 USD. But beware when laying: fiber optic cable should never be kinked!
