Cable Blog

While most home networking is done through a router with multiple Ethernet cables, you may not need to purchase all that equipment if you only have two computers that need to transfer files to and from each other. You can network two computers directly together using a single LAN cable ?local area network? known as a crossover cable.
1
Measure the distance between the two computers and write down the length. Purchase an Ethernet crossover cable that is slightly longer than the measured length (see Resources below).
2
Power off both computers completely. Connect one end of the crossover cable to the Ethernet network port on the back of one of the computers. Run the cable across to the other computer, and connect the other end into the computer’s Ethernet port.
3
Turn both of the computers back on, and wait for their operating systems to finish loading. Click on the “Start” button on either of the computers and then choose the “Control Panel” option. Scroll down through the list of options, and click on the icon labeled as “System.”
4
Wait for a new window to pop up asking if you want to proceed, and click on the “Continue” button. Scroll down to the “Computer Name” heading, and write down the entry listed under “Workgroup.”
5
Go to the second computer, and access the System menu in the Control Panel. Scroll down to the Computer Name heading, and click on the “Change” button. Type in the work group name you wrote down earlier in the “Workgroup” text box. Click on the “Apply” button.
6
Restart the computer to save the workgroup change. Navigate back to the Control Panel, and click on the “Network and Sharing Center” icon. Choose the “View Computers and Devices” option to gain access to the other computer’s files and folders.

The Xbox 360 HDMI Cable , included with the Xbox 360 Elite system or sold separately, enables a single cable to deliver HD video (up to 1080p) and multichannel surround sound to a TV or an audio/video surround receiver.
Connect to a High-Definition TV

The Xbox 360 HDMI Cable gives you the option of using a single digital AV cable to connect to a high-definition TV.

The Xbox 360 console and HDMI cable work with high-definition televisions including big-screen projection, plasma, DLP, and LCD TVs.
To connect your Xbox 360 console to your high-definition TV (HDTV):

1. Turn off your console.
2. If another AV cable (such as the component HD AV cable) is already connected to the AV port on your console, disconnect it before continuing.
3. Connect the HDMI AV cable connector to the HDMI AV port (not the standard AV port) on the console.
4. Connect the other end of the HDMI AV cable to the HDMI input on your TV.
5. Turn on your console. From My Xbox, System Settings, select the appropriate high definition video setting for your TV.

As odd as it might seem to non-technical people, it does really make a difference what cable you use to connect your PS3 to your TV. The cable helps to define what type of signal your TV receives. Think of it as listening to your CDs on a tinny little $5 plastic speaker, vs listening to your CDs on large, high quality multi-speaker surround sound.

The options for video (TV) output cable connection for your PlayStation 3 are composite and HDMI. Composite is the old style VCR type of cable where there is red and white to carry the right and left stereo signals, and a yellow plug to carry the video. If you use that set of plugs, that is ONLY regular TV quality. That is the maximum level of quality it can carry.

All PS3s ship with this composite cable as their default cable.

HDMI Cable To get a higher level of video quality from your PS3, you need to buy a separate cable – a HDMI cable. This carries high definition video plus audio, all in one rectangular-jack cable. This is sending in essence a bunch of zeroes and ones all in a stream. The transfer rate, if you’re curious, is 5 gigabit per second. In comparison, moving a high def movie signal only takes up 2.2 gigabits per second.

With analog cables, i.e. the older cables that sent sort of a “sound wave” of signal, it really mattered how high quality the cable itself was. Using gold plated connectors, shielded cables and so on could really affect the quality of that sound wave as it travelled from its source to its destination.

With new digital cables, this shielding really doesn’t matter that much. It’s moving 1s and 0s. It’s like a wireless network connection. You don’t worry about “walking between” that signal. It’s ones and zeros moving, which is simple to move around.

So that being said, your main concern when buying a HDMI cable is that it’s long enough to suit your needs. You don’t have to buy multi hundreds of dollars for a high end HDMI cable because it’s “better”. You can buy a standard HDMI cable and get the exact same level of quality.

Note that there is NO reason to get something “specific for a PS3″ here. Both ends of a HDMI cable is a HDMI jack. There’s nothing at all PS3 specific in this cable. You can get any HDMI cable in the world and it will work fine for your PS3 or for any other HDMI application you might use.

If you really want to go solely with Sony products, feel free to pay more for the Sony version of the HDMI cable, which is made by Monster. Monster is a well known name in high end cables. However, if you want to save some money, there are many other options out there for you to choose from.

One of the annoying things about breaking up with your boyfriend of many years is the process of moving on and being able to do things yourself again. There are certain things in my experience that I could have done without, but many things that I could have really used to help me on my daily life. Such is the sad notion of splitting with someone who was a computer genius and would always take care of my home technology system; however, this is the only thing I will miss of him as I do wish I had taken more notice of what he used to do.

Nevertheless, moving on is exciting and I soon learnt how to use a computer properly. It turned out that it was not as bad as one would think it to be. I decided that it was time that I begin learning about all things technological, considering I would be attached to my computer for a long time. I got a little carried away and came across terms like server racks, connectors, switches and patch panels. I never knew what any of these terms meant and decided to put my brain into use by researching this topic of networking.

Not everybody are technologically astute, even though I have been using my home computer for many years, I still need help in setting up the network connection between multiple computers. However, patch panels alone are an important and vital piece of equipment in the world of electrical and communication systems. You may or may not have heard of these, but I will try to give you a clear picture of what it would look to the nonprofessional.

Imagine a grainy film of the 1940′s, possibly during the Second World War and seeing the telephone switchboards. Back then, telephone calls were transferred from switching one wire from one connector and connecting it onto another socket. This method was known as ‘patching through’, which is putting the call through to the other person. These were the earliest forms of patch panels used for communication connections and have since developed into becoming a useful data-transferring device.

At this point one may be thinking how any of this is relevant to them. The point is that patch panels are good for connecting computers together for something called a LAN (Local Area Network). These are great for having people all networked together to transfer data, share files and best of all play games against each other (a great way of getting over the old ex!). These are important for connecting the computer to a network and onto the internet; hence it is good to be knowledgeable.

Note that this is a manual process of interconnecting cables, so you as the user would need to plug and unplug the cables keeping you in control of all of the connections. Of course, we no longer see these cables for connecting phone calls, but new alternatives and devices are still readily used today for communication networking. These are even used in music recording studios, broadcasting studios, telephone connections, computers, audio and video production studios, and other communication studios.

These are extremely cost effective and cheaper than most switching equipments. These also have a good power failing protector, which is handy for keeping this running smoothly and without losing any valuable information. They have also made available wireless patch panels, which works by switching connections simply by using a switch!

Maybe the best way to show you are doing well in getting over your ex, is by showing off your knowledge on how to network computers together and talk about patch panels. It works like a charm!

Possibly one of the most intelligent electrical devices invented for fast connectivity and transference of data is the patch panel. As much as one would normally shrug their shoulders after hearing the name, it is something that is extremely useful and can be used for virtually anything that requires a fast connection. They are typically seen in household connectors, with the shorter cable into the front of the patch panels, and the longer cable connected to the back.

Historically these were seen in black and white movies, where a wonderful image of a female operator was busy switching the cables on a patch panel connecting and transferring telephone calls. To this day these are still used for telephone usage and connecting line communication between people. These are popularly used for transferring data information and connecting up audio and visual equipment.

The patch panels can come with cables of varying lengths, which can also be available with different types of connectors. An example of this is the break box, which has its own connector on the front and other compound connectors on the back that other cables can plug into. Some breakout boxes are made with an even number of connectors on each side, however some are made with a random number of connectors.

These are more commonly used for connecting computers up together for networking computers up together under the same network. They are useful for connecting the computers onto the internet; the Local Area Network (LAN) uses them to connect a number of computers together to use the internet. Similarly they are also used to connect the LAN onto the WAN (wider area network).

The patch panels transmit signals from one cable to another without losing any data during the transmission process. These panels may seem like just another cable but they are one of the best tools for data transference, making them reliable and efficient. It is also easy to change cables from the front, switching them without losing the signal, as the rear of the panel does not differentiate the cable signals from each other.

As technology has developed the panels have come in very useful for many companies and businesses, as they are essential for passing on information. New software’s have been developed to enhance the efficiency of the patch panel, in transferring data. The software monitors, and records, the data that is being transferred, making it easier to keep track of important work being transferred monitoring any problems or issues that may arise.

These are also good for maintenance of the cables and the panels. They track any changes in the core temperature and also any fluctuations in the power supply. The panels are more easily updated and any issues can be resolved swiftly without having to dig too deep into the machine.

The need for reliable long-distance communication systems has existed since antiquity. Over time, the sophistication of these systems has gradually improved, from smoke signals to telegraphs and finally to the first coaxial cable, put into service in 1940. As these communication systems improved, certain fundamental limitations presented themselves. Electrical systems were limited by their small repeater spacing (the distance a signal can propagate before attenuation requires the signal to be amplified), and the bit rate of microwave systems was limited by their carrier frequency. In the second half of the twentieth century, it was realized that an optical carrier of information would have a significant advantage over the existing electrical and microwave carrier signals.

In 1966 Kao and Hockham proposed optical fibers at STC Laboratories (STL), Harlow, when they showed that the losses of 1000 db/km in existing glass (compared to 5-10 db/km in coaxial cable) was due to contaminants, which could potentially be removed.

The development of lasers in the 1960s solved the first problem of a light source, further development of high-quality optical fiber was needed as a solution to the second. Optical fiber was finally developed in 1970 by Corning Glass Works with attenuation low enough for communication purposes (about 20dB/km), and at the same time GaAs semiconductor lasers were developed that were compact and therefore suitable for fiber-optic communication systems.

After a period of intensive research from 1975 to 1980, the first commercial fiber-optic communication system was developed, which operated at a wavelength around 0.8 µm and used GaAs semiconductor lasers. This first generation system operated at a bit rate of 45 Mbit/s with repeater spacing of up to 10 km.

On 22 April, 1977, General Telephone and Electronics sent the first live telephone traffic through fiber optics, at 6 Mbit/s, in Long Beach, California.

The second generation of fiber-optic communication was developed for commercial use in the early 1980s, operated at 1.3 µm, and used InGaAsP semiconductor lasers. Although these systems were initially limited by dispersion, in 1981 the single-mode fiber was revealed to greatly improve system performance. By 1987, these systems were operating at bit rates of up to 1.7 Gb/s with repeater spacing up to 50 km.

The first transatlantic telephone cable to use optical fiber was TAT-8, based on Desurvire optimized laser amplification technology. It went into operation in 1988.

TAT-8 was developed as the first undersea fiber optic link between the United States and Europe. TAT-8 is more than 3,000 nautical miles (5,600 km) in length and was the first transatlantic cable to use optical fibers. It was designed to handle a mix of information. When inaugurated, it had an estimated lifetime in excess of 20 years. TAT-8 was the first of a new class of cables, even though it had already been used in long-distance land and short-distance undersea operations. Its installation was preceded by extensive deep-water experiments and trials conducted in the early 1980s to demonstrate the project’s feasibility.

Third-generation fiber-optic systems operated at 1.55 µm and had loss of about 0.2 dB/km. They achieved this despite earlier difficulties with pulse-spreading at that wavelength using conventional InGaAsP semiconductor lasers. Scientists overcame this difficulty by using dispersion-shifted fibers designed to have minimal dispersion at 1.55 µm or by limiting the laser spectrum to a single longitudinal mode. These developments eventually allowed 3rd generation systems to operate commercially at 2.5 Gbit/s with repeater spacing in excess of 100 km.

The fourth generation of fiber-optic communication systems used optical amplification to reduce the need for repeaters and wavelength-division multiplexing to increase fiber capacity. These two improvements caused a revolution that resulted in the doubling of system capacity every 6 months starting in 1992 until a bit rate of 10 Tb/s was reached by 2001. Recently, bit-rates of up to 14 Tbit/s have been reached over a single 160 km line using optical amplifiers.

The focus of development for the fifth generation of fiber-optic communications is on extending the wavelength range over which a WDM system can operate. The conventional wavelength window, known as the C band, covers the wavelength range 1.53-1.57 µm, and the new dry fiber has a low-loss window promising an extension of that range to 1.30 to 1.65 µm. Other developments include the concept of “optical solitons, ” pulses that preserve their shape by counteracting the effects of dispersion with the nonlinear effects of the fiber by using pulses of a specific shape.

In the late 1990s through 2000, the fiber optic communication industry became associated with the dot-com bubble. Industry promoters, and research companies such as KMI and RHK predicted vast increases in demand for communications bandwidth due to increased use of the Internet, and commercialization of various bandwidth-intensive consumer services, such as video on demand. Internet protocol data traffic was said to be increasing exponentially, and at a faster rate than integrated circuit complexity had increased under Moore’s Law. From the bust of the dot-com bubble through 2006, however, the main trend in the industry has been consolidation of firms and offshoring of manufacturing to reduce costs.

Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals. Due to much lower attenuation and interference, optical fiber has large advantages over existing copper wire in long-distance and high-demand applications. However, infrastructure development within cities was relatively difficult and time-consuming, and fiber-optic systems were complex and expensive to install and operate. Due to these difficulties, fiber-optic communication systems have primarily been installed in long-distance applications, where they can be used to their full transmission capacity, offsetting the increased cost. Since the year 2000, the prices for fiber-optic communications have dropped considerably. The price for rolling out fiber to the home has currently become more cost-effective than that of rolling out a copper based network. Prices have dropped to $850 per subscriber in the US and lower in countries like The Netherlands, where digging costs are low.

Since 1990, when optical-amplification systems became commercially available, the telecommunications industry has laid a vast network of intercity and transoceanic fiber communication lines. By 2002, an intercontinental network of 250,000 km of submarine communications cable with a capacity of 2.56 Tb/s was completed, and although specific network capacities are privileged information, telecommunications investment reports indicate that network capacity has increased dramatically since 2002.
