No longer a new technology in principle, but still pretty new in implementation, fiber optics are bringing a new communication revolution silently. These extreme fragile optical cables can transfer a huge amount of data over large distances with a very high bandwidth at a very small loss. The optical cables are not cheap, but their mass manufacture has now made them cheaper than ever.
Optical technology uses a reflective surface inside the optical cables to carry light signals inside the cable. The light signal is not weakened even over large distances that’s why these cables do not require as many repeaters as a conventional cheap cable would require. That’s why optical fibers can are used to carry huge amounts of data between distances as large as continents cheap. These days all the Internet data between countries and continents are carried exclusively in fiber optic cables.
But fiber optical cables are not just used for mass data transfer purposes alone. These days there are thinner fiber optic cables used to transfer high-bitrate multimedia data even in home devices. The fiber optic cables have also been used in network devices for amazingly high transfer rates. But the fiber optical cables are not as cheap as the conventional data cables and that’s why they are not so widely adopted yet.
But many new devices make use of optical fiber technology to sustain the high data rate transfer they need. That’s why the optical fiber cables are being mass manufactured today, and they have become cheaper. They’re not dirt cheap yet, but given time the prices will be more affordable.
The most popular consumer implementation of optical technology is in HDMI standard. The HDMI standard is the high-definition multimedia communications standard that is being widely adopted in PCs, blu-ray discs, game consoles and other multimedia devices for the home. The HDMI cables are copper optic cables that can handle high-definition video and multi-channel audio, offering data transfer capabilities that were earlier impossible. Because they are based on copper optical tech, the HDMI cables are not cheap.
HDMI optical interface is being pushed by a consortium of technology companies that has leaders like Sony, Philips and Hitachi. The consortium partners have made wide use of HDMI interface in their own devices, and are promoting the interface among other manufacturers too. A common communication interface will help in standardization and will make HDMI cables cheap, benefitting the customer.
The best source for cheap HDMI cables is the Internet. Most electronics stores have a very high markup on the price of the cables and if you shop from an exclusive fiber optical cable source, you can get the cables at a much lower price. That’s why most buyers of optical cables prefer getting cheap cables online instead of paying more offline.
If you’re going to shop online for cheap optical cables, try to look for a source that offers free shipping. That will cut down your cost even lower.
