What is the top of the light?
Light Peak is a computer cable technology designed by Intel® to replace a large number of different connections found on computers and personal electronics. Initial revisions support data speeds of up to 10 gigabits per second and future versions have managed to handle up to 100 gigabites per second. Existing connection technologies can be supported and transferred via the cable using electrical or optical technology. Light Peak was rebrated in 2011 as Thunderbolt ™. The company was hoping to replace general accounting connections, such as a universal serial bus (USB) and more specific technologies such as a high -resolution multimedia interface (HDMI) with a single physical interface, eliminating the need for different cables. This could allow a laptop to have a single cable interface with Thracity to connect to accessories such as external hard drives and scanners, as well as monitors, projectors or TVs.
To support multiple devices at once, Light Peak was designed with a much higher bandwidth than competing technology. The initial version of the technology supports up to 10 gigabits of data per second and Intel® claimed that this could eventually be extended to 100 gigabits per second. For comparison, USB 3.0 has a maximum theoretical data speed of 4.8 gigabits per second. The light peak also supports a fully duplex connection, ie data can be sent and received at the same time. Daisy can also be attached to the device, allowing one port to connect to multiple devices without using a hub.
Existing connections such as PCI Express and DisplayPort can be sent via a bright peak connection, so one cable can connect a computer to a high -resolution TV (HDTV). The controller chip would encapsulate these protocols and send them through a light top cable to the target device where the protocols are returned to their native state. As part of this LZ settingsE Existing software use without new devices. The physical connector is the same as using Mini DisplayPort and existing displays can be used in compatibility mode.
In February 2011, the first computers and devices compatible with this technology were announced, rebrated as Thunderbolt ™. Although timely light demonstrations of the maximum light had optical fiber cables driven by small lasers, the first products equipped with Thunderbolt ™ use traditional electrical signals compared to copper cabling. Both connection types are supported under the new standard, each offering clear benefits. Connection only for electrical value is cheaper and can provide external devices of up to 10 watts, but are limited to 9.8 feet (3 meters). More expensive optical cables can support much longer distances but cannot power the device.
