Categories network cables

Depending on the quality and type, network cables are classified into categories that help us know the characteristics of them.

The categories of network cables most commonly used are:

- Category 5
- Category 5e
- Category 6
- Category 6
- Category 7

As can be seen, category 5e (enhanced or improved) and category 6A (Augmented), are an improvement of categories 5and 6, respectively, which it has improved the top speed and bandwidth.

The higher the category, the higher the speed of maximum data, the maximum 100 meters distance as its standard.

You can see a table which shows the 5 categories, where V is the maximum velocity, D is the maximum and MHz frequency which can work away.

DC jack connector

Inside the different types of connectors for power supply we find one of the most common, the DC jack. Used in most connections in electronic devices such as routers, laptops, printers etc ... is the most used due to its easy assembly and connection. These connectors are mostly used in DC power supplies and installations.
The connector is cylindricalAnd we find its version in male and female format (A). The male connector is composed of the outer and inner metal part, where in each of them the energy travels, normally the inner part is used for the positive pole and the outside for the negative, but may vary according to manufacturer.
This type of connector is found in many diameters, the most common are 3.5mm and 5.5mm. Although we can andThere are several measures in terms of length and outer or inner diameter.
Its installation is simple, we can find several types of connectors, pair to weld or to screw with terminal block, it will depend on the user to choose the most suitable in its installation.
When purchasing the male connector to perform a repair we must know its diameter, length of the connector and internal diameter. If we proceed with aTo new installation only we must make sure that the male and female connector are of the same characteristics.

Communication Series

RS-232 (Recommended Standard 232, also known as EIA/TIA RS-232C) is an interface that designates a standard for the exchange of a series of binary data between a DTE (Data Terminal Equipment) and DCE (Data Communication Equipment , Data Communication Equipment), although there are others in which the RS-232 interface is also used. An equivalent definition published by the ITU is called V.24. The RS-232 is a connectorDB-25 type (25-pin), although it is normal to find the version of 9-pin (DE-9, or popularly also called DB-9), cheaper and even extended to certain types of peripherals (such as serial mouse PC).

When we talk about RJ45 ("Registered Jack" 45) we refer to a telecommunications network interface for wired connection of voice and data equipment.

This connector has 8 pins or connections and may have a specific category depending on the data transfer speed and bandwidth (category 5e, 6, etc.)

The common application is their use in Ethernet network cables under TIA/EIA-568-B standard that defines the arrangement of pins (pinout), but can also be used for other applications.

The crossover cable has one end with EIA-568A scheme and the other one with EIA-568B.



It is a special multi point communication for industrial machinery by its format adapted to long distance and heavy machinery. The connector is used to connect the DB9 serial port or popularly called. One characteristic is that it is able to greatly reduce the noise so that the distance is much greater.



VDC would be the abbreviation for Volt Direct Current which translated would volts direct current. The idea of ??this type is unidirectional current to the load. Direct current is normally produced by batteries, thermocouples, solar cells and a dynamo electric machine type. The direct current can flow in conductors such as wires, but may also flow through semiconductors, insulators ...

The Wifi technology is a wireless communication mechanism between devices. This technology allows you to connect devices such as computers, laptops, mobile etc... to the Internet or communicate with the devices themselves.

Applications can be several, among the most common are the access points, ideal for giving and sharing a connection signal to multiple devices. It is the typical configuration of a home user.
Repeater, ideal to repeat and amplify weak signal.

The power and range between devices basically depends on the antenna and its hardware.

The wireless signals work under a unified standard regulations, the standard that is based on the IEEE 802.11. These include IEEE 802.11b, IEEE 802.11g and IEEE 802.11n working at 11 Mbit/s, 54 Mbit/s and 300 Mbit/s, respectively.
Being any device with a standardized protocol such technology can connect to another using the same technology, making it a kind of universal connection.

The wireless networks are characterized by the ease and convenience of making connections in infrastructure, since it is not necessary to perform network cable installations.
it also allows connecting a lot of devices to a single node.
