With every passing day, new scientific and technological advancements are being incorporated into a wide range of household devices such as walkmans, portable DVDs, CD players, Digital Audio PCs, and MP3 players to name a few.

Consumer audio cables are the primary means through which consumers are being provided the advantages of new innovations in audio features and the leading to improvement in sound quality. They are used to enhance the quality of audio output by transmitting the respective sound frequencies and signals between the input and output device.

A consumer home audio cable is categorized on the basis of the manufacturing company as well as the specific device for which they are used. Stereo audio cables have become an essential part of household audio devices as they enable the user to connect any kind of portable stereo device to multimedia speakers.

The standard stereo audio cable has two 3.5mm male connectors on each end along with 29-gauged stranded conductors with a drain wire. The conductors are usually shielded with aluminum foil to reduce interference to the maximum extent possible. Apart from high quality sound, stereo audio cables also provide maximum utility in terms of conversion of audio from PC sound card and miniature audio devices to output devices with enhanced sound features.

For professional musicians and technicians who deal with complex equipment there is the Professional Studio Mono ¼” to ¼” Male Guitar Cable. The cable is mainly used to connect microphone level outputs to recorders, amplifiers and mixing consoles that can incorporate an unbalanced line. It has 18 A WG twisted pair connection for the transmission and output of the finest quality sound. And triple insulation is ensures accurate signal transfer and to reduce dielectric loses to the maximum extent possible and the nylon sleeve provides protection as well as durability.

A Straight Patch cable or Ethernet cable is one consisting of 8 pins and thus 8 wires. Both ends of an Ethernet cables are fitted with RJ45 or GG45 male connectors that allow them to be used in networking. I will now explain the different types of straight patch cables…

The categories are referred to as Catx. The ‘x’ is replaced by a number which will define the performance of the cable with accordance to the norms set by the Electronic Industries Association (EIA).

You should firstly be aware that the categories are backward compatible. This means that category 6 components can be used in a network using category 5. However, the whole performance would be that of a category 5.

The spectral Bandwidth for the Cat5e, Cat6 and Cat7 cables are as follows: 100MHz, 500 MHz and 600 MHz respectively. The attenuation as well as the impedances is also improved as you switch to Cat7. 22dB is a typical attenuation for Cat5e while 19.8 dB is a typical value for cat6 cables.

The cables also have different diameters. Cat5 ones would be of about 5.5 mm while Cat6 ones are approximately of 5.8mm. That point should be considered when wiring through pipes or channels. This is not only because of the use of larger copper wires but also due to the fact that internal separators are also used. The later divides the pairs and thus reduces noise.

To be able to cater for less noise than Cat6, the Cat7 cables make use of shielding. Individual wires and the cable as a whole have been fitted with additional shields. If GG-45 or Tera connectors are used at both ends, you would be able to transmit information on a 10 GB network at a frequency of 600 MHz.

Well, it means Registered Jack and forms part of the Code of Federal Regulations in the USA. To get a better image, the RJ45 is a bit bigger than the telephone jack. Got it? The RJ45 connector is used for linking telecommunication as well as computer equipment. You should also be aware that the RJ-45 consists of 8 wires of different colors and thus of 8 pins. A cable with RJ-45 at both ends is referred to as an Ethernet cable.

The wires are of eight fixed colors and follow the EIA/TIA 568A and 568B standards. The colors are white, green, orange, blue, orange and brown.

You should also be aware of the fact that plugs and jacks are termed modular connectors which can be distinguished from the telephones one. The main difference is that the telephones connectors are that they are linked to the walls.

If the wiring of your computer network is functioning allows you to communicate at the speed of 10/100 Mb/s, only the 1-2 and 3-6 pins are used to transmit information. However, if the network is running on a 100Mb/s, all the pairs and wires are used to transmit information.

When you connect your terminal to a hub, switch or router you should use a straight cable. However, if you use a crossed cable to connect two computers together, a crossed cable should be used unless you are on a Gigabit connection. This would spare you buying a hub. In a crossed cable, the wiring is as follows: the transmission pair of one RJ45 end is connected to the reception pins of the other end. T568A and T568B are two alternatives of the crossed cable.

The ISO has defined the RJ-45 connector as 88766. This has enabled the modular RJ-45 connector to be used as an international one.

The ever increasing demand for high definition sound and audio devices has lead to the rise of corresponding cables and accessories with a whole range of functions and utilities. Electronic audio devices such as DVD players, walkmans, MP3 players, home theatre systems and Ipods are being adapted to the needs and requirements of the user.

The invention of optic fiber technology has revolutionized the manner in which data is transmitted. Optic fiber networks now span the length and breadth of the globe making it possible to transfer data at high volumes and speeds, resulting in enhancing the efficacy of all data related applications. Optic fiber technology has contributed to shrinking the globe.

In the recent past it has certainly become evident that fiber-optics are steadily and surely taking the place of copper wire as a more efficient media for transmission of communication signals. They interconnect the extensive distances separating local phone networks and also provide the backbone for various other network systems. The other applications include cable television services, office buildings, university campuses, electric utility companies and industrial plants

Though optic fiber is a physical media and more expensive, as compared to radio waves, it is more reliable and secure and is extensively used in national networks that require a high degree of secrecy. Most local Area Networks are completely dependant on optic fiber. After data is transferred over phenomenal distances using a mix of various media, that includes satellite communication, optic fiber is generally used for end point connectivity.

Optic fiber does not suffer from bandwidth and congestion problems like radio communication does, and hence there is no limit to the spread of any network, as long as it is affordable and physically feasible.

Fiber Optics therefore score over competing media in the following areas
SPEED: networks using Fiber optics operate at very high speeds - at gigabit rates.

BANDWIDTH: large data carrying capacity.

DISTANCE: Signals can be transmitted over greater distances without the need for “refreshing” or strengthening.

RESISTANCE: Greater resistance from electromagnetic noise such as motors, radios, and other proximal cables.

MAINTENANCE: maintenance of Fiber optic cables costs much lesser.

Many of us face the common problem of network liabilities and difficulties of setting it up to attain a hassle free condition. For those who are in the business of setting up of LAN, WAN or other networks can themselves understand the pressure of maintaining it properly.

There are many types of equipment and items for network build up. One of them is the patch panels. A patch panel provides as a junction for the incoming and outgoing connections of a LAN. It is a board of network ports assembled and connected to each other. They are also used in the telecommunication industry.

In a LAN setup, computers get connected to each other and to the internet by the help of patch panels. During network liabilities it is easy to align and realign the patch cords, which setup the connection to the patch panel. The entire circuit can also be reconfigured. This is the main utility of having a patch panel.

Network administrators and cable communication experts can easily alter the path of chosen signals without the aid of switches by the help of a patch panel.

Apart from the use of a patch panel, a relay rack is the other most sought after item in the networking and cable communication industry. Generally they are 2-post or 4-post steel structure used for installing computer, cables, network equipments etc. Some of them have pre-installed cable management facilities.

Nowadays a relay rack is manufactured with various other optional accessories. They have EIA standard mounting holes for mounting. Wall mountable and open server installable relay racks are much common nowadays.

They save a lot of space by accommodating various equipments in an organized fashion. With easy installation procedures it doest cause any trouble in network organization. No doubt they save a lot of your valuable money and time.

Patch panels are panels that are usually used for connectivity purposes. It is a very functional and common house cable connection. A shorter patch cable can plug or connect into the front side, whereas the rear end will occupy the connection aspects of a longer cable that is permenant. The congregation of hardware is placed in such a manner so that a number of circuits involved are typically of similar type, and then appear on jacks for supervising the interconnection, and checking the circuits in a conducive and convenient manner.

Patch panels offer the freedom to allow the technicians to alter the path of the selected signals very quickly, without bearing the cost of the various dedicated switching equipments. This was primarily employed by telephone exchanges of early times, where the telephone switchboards & a huge room full of those telephone operators were ever-present. Theese are not only employed in the telephone and data services but also in other audio, video appliances. Patch bays are used during installations where they become a significant aspect in order to connect & reconnect the various hardware devices.

Another important & quite prevelant device is the Relay Racks used for mounting various electronic modules in a “Rack” that measures to about 19inches. Equipments which are designed in such a way so as to be placed in a rack are said to be rack mounted chassis. Due to their origin as mounting techniques or arrangements, employed for rail line signaling relays, they are still frequently known as relay racks, but the 19-inch rack composition has prevailed constantly while the technology that is mounted within it has advanced and has been altered to entirely different fields. This standard rack arrangement is popularly used throughout the entertainemnt, music, telecommunication industries.

So, the above two features described briefly are quite important in the connectivity aspects and processes in the modern days. They are not only useful but also easily attainable & convenient for any technician or even for the common man.
