All You Need to Know About Digital Optical Cables

Wednesday, April 7th, 2010

Do you know what a digital optical cable is? Do you know what this cable does? Don’t worry; a lot of people have heard of this type of cable, but do not know a lot about it. These are some things that you may want to know about the digital optical cable?

1. What exactly is a digital optical cable?

This cable is a fiber-optic technology that transmits sound signals. This audio cable is made up of multiple strands of glass that send digital information to receivers. The cable is also commonly called a Toslink, which means Toshiba-Link. Toshiba, the electronics company, originally invented this technology before CD player manufacturers borrowed the idea.

2. What electronics use a digital optical cable?

Digital optical ports are found in certain music players, and are common in CD and DVD players and video game consoles. Basically, this cable is used for entertainment and home theater purposes. However, this audio cable is also used for applications such as car navigation and audio, and office or factory automation.

3. How is this cable different from a coaxial cable?

The digital optical cable uses on and off pulses of light in order to transmit an audio signal. It carries the same signal from the beginning of the cable to the very end. Since light can be refracted without losing or changing the signal, the signal will arrive at the receiving end in its purest form.

The coaxial cable is similar to the RCA cable, except it focuses solely on sound. This particular kind of cable sends out electrical signals using a copper wire. However, dealing with factors such as copper wire and electricity causes the signal passing through the cable to degrade a little.

4. Is the Toslink cable expensive?

Yes. A digital optical cable is more expensive compared to other similar options. While traveling through the cables, the pulses of light retract more quickly and clearly compared to other types of cable. The quality of signal obtained from this type of cable is superior to other cables. For this reason, you’ll find that this audio cable costs more per foot than other cables.

5. Why should I purchase a Toslink cable?

An average person won’t really notice a big difference between coaxial and digital optical cables. A lot of audio equipment is made to support both kinds of connectors. However, the digital optical cable would be a good choice for someone very finicky about the definition and clarity of sound. Audiophiles, in particular, choose this audio cable.

All You Need to Know About Laptop Power Cords

Wednesday, April 7th, 2010

With today’s technology-laden world, it is highly probably that you own a laptop, or at least know someone who does. Every laptop owner or user knows what a laptop power cord or adapter is. Do you?

Here are some useful bits of information that you should know about power cords:

1. The power cord is an essential accessory for the laptop.

Obviously, the adapter is the one thing that can charge your battery. A fully charged battery on a laptop will last an average of about 2 to 5 hours. You will eventually need to use the laptop power cord to charge your computer’s battery. Without a power cord, your laptop is pretty useless.

2. A laptop power cord is useful for people who travel.

Power cords are extremely useful for people who travel often. If you need to work on your computer while out of town, you don’t need to print out all the documents that you need to go through. Neither will you have to rely on your short battery life. You simply need to find a socket, plug in your computer and use your laptop as much as you like.

3. You need to change your power cord if it will not charge your laptop.

You may find that your laptop has no power, even if your computer is plugged to the wall. You may need to replace your laptop power cord. Sometimes, the adapter shorts, which prevents your battery from charging. You’ll know that you need to change your power cord when the light on it is not illuminated, even while it is plugged into a socket.

4. Some users have more than one laptop power cord.

Some users own two or more power cords. You may find it hard to believe, but it is true. As mentioned earlier, the adapter is the most important laptop accessory. Imagine the chaos if you had to give a sales presentation to your boss, only to find out that you forgot your laptop power cord at home? You could use one charger at home and leave it there. Then, you could place another charger in your laptop bag to be used when you are outside the house. A power cord doesn’t weigh much, and it doesn’t take up a lot of space.

5. Not all power cords are the same.

You might discover that your power cord fits on a friend’s laptop of a different brand. Remember that this isn’t always the case. Although some power cords do fit in other laptops, they may not work properly. Laptop models use adapters of different sizes and wattages. It is always best to use the prescribed power cord for your computer in order to avoid damaging it.

All You Need to Know About Optical Toslink Cables

Wednesday, April 7th, 2010

If you’ve ever surfed the Internet or shopped around for audio equipment, you may have come across an unfamiliar term like Toslink. Some of you may know that Toslink is an audio cable—but there’s plenty more to learn about this particular cable:

1. Toslink stands for Toshiba-Link.

The optical Toslink cable is a brainchild and registered trademark of the established electronics company, Toshiba. Toslink stands for Toshiba-Link, although it’s generic name is EIAJ optical.

The Toslink cable was originally created to connect a CD player to a receiver for PCM audio streams. Shortly afterwards, CD player manufacturers adopted this innovation.

2. The Toslink cable is used for audio equipment.

Most likely to use an optical Toslink cable are pieces of equipment that carry a digital audio stream between components. This audio cable supports many different physical standards and media formats. Examples of such equipment are CD players and DAT recorders.

Computers generate a lot of electrical noise, and the Toslink cable was designed to eliminate ground loops, as well as isolate the sender and the receiver. The digital transmission of sound or data is not affected by electromagnetic noise.

3. The Toslink cable is a fiber connection system.

This audio cable may either be made of inexpensive or higher quality fibers. The basic Toslink may use 1mm of inexpensive plastic optical fiber. On the other hand, the Toslink cable can also use multiple strands of plastic optical fibers of higher quality. Quartz glass optical fibers may also be used. Ultimately, it depends on the desired application and bandwidth.

The Toslink is usually limited to a length of 5 meters. Without a signal booster, it has reliable transmission at a technical maximum of 10 meters in length.

4. The optical Toslink cable is made up of four components.

The Toslink cable is composed of the transmission module, the receiving module, the optical fiber cable and the optical connectors. The transmission module turns electrical signals into optical signals. The receiving module, on the other hand, converts the optical signals back into electrical signals. The optical fiber cable serves as the physical transmission line. The optical connectors, as the name denotes, connects the transmission module and the receiving module to the optical fiber cable.

5. You can connect a Toslink cable to a Mini-Toslink jack.

A mini-Toslink jack looks very much like a 3.5 mm stereo minijack except that they are 0.5mm longer, and the tip has a finger connection. The mini-Toslink jack is common among portable minidisc players and Apple computers. You can purchase an adapter to connect your optical Toslink cable to the mini-Toslink jack.
