Macbook Pro with light peak

according to reports,Apple is set to unveil a MacBook Pro using Intel's next-generation interconnect, Light Peak.Light Peak was first unveiled by Intel in 2009. The interconnect was initially supposed to use optical technology to transfer data at speeds of up to 10Gbits/sec, but has since been knocked back to copper following price concerns. Intel initially said it could arrive this year.

One manufacturer long rumoured to be looking at Light Peak as a replacement for USB has been Apple, and the latest report from CNet suggests it could arrive with the expected update of the MacBook Pro this week.
The report said Apple was expected to unveil a new high-speed interconnect this week, according to a source close to the company. Whether it is indeed Light Peak, or Apple's own creation, remains to be seen.
Reports last year suggested Apple originally brought the idea of Light Peak to Intel, asking it to develop the technology.
Intel has already unveiled the follow up to Light Peak, which promises speeds of 50Gbits/sec.


Light Peak Overview


Light Peak is a new high-speed optical cable technology designed to connect your electronic devices to each other. Light Peak delivers high bandwidth starting at 10Gb/s with the potential ability to scale to 100Gb/s over the next decade. At 10Gb/s, you could transfer a full-length Blu-Ray movie in less than 30 seconds. Optical technology also allows for smaller connectors and longer, thinner, and more flexible cables than currently possible. Light Peak also has the ability to run multiple protocols simultaneously over a single cable, enabling the technology to connect devices such as peripherals, displays, disk drives, docking stations, and more. . Light Peak components are expected to begin to become available to customers in late 2010, and Intel expects to see Light Peak in PCs and peripherals in 2011.

Existing electrical cable technology in mainstream computing devices is approaching practical limits for speed and length, due to attenuation, noise, and other issues. However, optical technology, used extensively in data centers and telecom communications, does not have these limitations since it transmits data using light instead of electricity. Light Peak brings this optical technology to mainstream computing and consumer electronic devices in a cost-effective manner.
Multi-Protocol Enables new and innovative usage models.
Light Peak consists of a controller chip and an optical module that would be included in platforms supporting this technology. The optical module performs the conversion from electricity to light and vice versa, using miniature lasers and photo detectors. Light Peak also includes a controller chip that Intel will provide. The controller chip provides protocol switching capabilities to support multiple protocols over a single cable. Today, if you want to plug a display into PC one needs a display cable plugged into a display connector. Likewise if one was to plug a projector into a PC a different projector cable and connector are needed. Not so with Light Peak, because the Light Peak controller implements multi-protocol.
The multi-protocol capability the controller implements is an innovative new technology that will enable new usage models like flexible system designs and thinner form factors, media creation and connectivity, faster media transfer and cable simplification. As end users rely more on their PC’s and CE devices as they go mobile, they want smaller and thinner form factors.
