The possibilities of light peak technology interested many users and participants in the market. Flexible optical cable is capable to transfer information with the speed of 10 Gbit/s to the distance of up to 100 m. Moreover, one physical channel can be used for the transmission of information simultaneously on several protocols.
We start the Story about the prospects of Light peak introducing from the photographs of some devices, which support USB 3.0 interface, which were demonstrated on IDF fall 2009. Associate explains, that asus company on its motherboard P7P55D deluxe realized USB 3.0 support using the discrete controller, on the PCI express x1 interface.
Thus, user can hold this USB 3.0 controller in the box until required . Let us recall that SATA-600 support by asus company will be realized analogously.
With the hard disks, using SATA-300 interface, the USB 3.0 controllers can communicate with the aid of special adapters - the appropriate product was demonstrated by Fujitsu company .
Associates also attempt to explain, why Intel does not hurry to inject USB 3.0 support on its chipset. The additional crystal area, necessary for the realization of USB 3.0 controller become small only after transfer on 45 nm technology. However, Intel will release chipset on 45 nm technological not earlier than 2012, when processors will be released on 22 nm technology.
Already with the introduction of USB 3.0 engineers encountered limitations, superimposed by the possibilities of copper cable - it was necessary to decrease the maximum length of cable from five to three meters. Sooner or later, as consider USB-IF committee , high-speed wire interfaces will pass to optical connection.
USB-IF looks at light peak technology, but does not see in it a threat for USB 3.0. Related Products :
