Comparing VGA, Video Graphics Array, cables and Toslink cables will mostly focus on differences as the only similarity is transmitting electronic signals. That’s the only thing they do in a similar fashion, mostly there are differences here about function and design on these cables.
Some other common names used for VGA cable is the mini D15, RGB and D sub 15. The purpose of these is to give a type of the connector end of the cable, which has three rows of five pins for each one. Using these connector combinations and cables are for transmitting Red Green Blue Horizontal Vertical sync analog video signals and other similar data information. Generally these cable and connectors are implemented in use of connecting a VGA monitor to a computer.
VGA itself refers specifically to the video display type that was first distributed commercially on IBM computers in 1987. However, today a VGA cable may be used to connect a variety of video production hardware with an equally varied amount of video display hardware, the signal being limited to analog video only. As technology improves, VGA hardware connection types are slowly giving way to more sophisticated display technology and connectors such as the HDMI or High-Definition Multimedia Interface cables and connectors that are used for simultaneously transmitting both digital high definition video and digital audio.
One of the differences is that the Toslink cable is only for transmitting digital signals. This cable is created by Toshiba, and is a registered trademark of that company, the name is derived from Toshiba-Link. But there’s a generic name, EIAJ optical, from Electronic Industries Association of Japan. It was created by Toshiba to link their CD player to their PCM audio stream receiver technology. Toslink carries only digital signals through its fiber optic construction, while VGA is only analog video signals.
The optical fibers in a Toslink cable may consist of a variety of constituents ranging from thin plastic optical fiber to high-quality glass, depending on the application. Generally, they have a maximum length of about 15 feet although technical specifications may list a maximum length possible of up to 33 feet. Although many people believe the red colored light transmission in the cable originates from some sort of laser, it actually is produced by a single red LED or light emitting diode.
