What is an optical USB?
Optical USB is usually used to indicate Universal Serial BUS (USB), which uses optical technology such as optical optics, to improve data transfer speed. This term is sometimes used to indicate USB 3.0 technology; However, there are somewhat contradictory reports of the use of optical technology in standard USB 3.0 specifications. Optical USB can also refer to the use of optical technology in cables and USB connectors, such as extension cables and optical USB hubs.
USB cables and ports are usually used to connect various computer devices and hardware. This may include printers and scanners, as well as cameras, mobile phones and data storage devices such as external hard drives. One of the main limits with most USB technology, which was implemented at the beginning of the 21st century and at the end of the 20th century, is the basic limit of data transfer rate due to the nature of the USB cables. Optical USB would improve the output of optical fiber cablesEN with standard copper cables usually used in USB connectors, allowing much greater data transfer speed.
Initial reports regarding USB 3.0 release in 2008 suggest that optical technology is probably used to significantly improve data speed. However, the following reports seem to have a lack of optics of the fiber as part of the USB 3.0 standard, which means that the optical USB does not have to be its own part of USB 3.0. In 2010, the first commercial USB 3.0 products were available to consumers and the early analysis of these products showed improved data speed, but it seems that USB optical technology does not seem to be present.
However, there are various other uses for USB optical technology that could be introduced, such as the use of optics fiber in USB extensions to prevent signal loss. One of the main disadvantage of USB 3.0 technology is that PR cableso USB 3.0 would have a shorter maximum length than other types of data cable. Cables and hubs can be used to increase this distance, but these cables would have to be designed to prevent signal loss. The USB optical cables would probably be able to extend this distance and maintain signal strength.
HUBS used to allow multiple users to connect to a single USB 3.0 device could also use USB optical technology, but it does not seem to be an industry standard. While the USB 3.0 has improved data speeds compared to previous versions, it could potentially increase even more by fiber optics. This type of improved performance would probably be the option used by some manufacturers and does not seem to be part of the standard USB 3.0 specifications.
