Intel said on Monday that optical cables for its Thunderbolt portare scheduled to arrive later this year and will allow for longercables and eventually faster speeds. The world's largest chipmaker issued a statement on Monday confirming its plans to release the new cables this year, IDG News Service reports. Current Thunderbolt cables utilize copper with a maximumeffective length of six meters. Intel spokesman Dave Salvador told the publication that opticalcables will support data transfers over distances of tens ofmeters. As the technology develops, they will also make broaderbandwidth a possibility. However, one downside to the opticalcables is that connected devices will require their own powersupplies. The current generation of copper Thunderbolt cables can provide upto 10 watts of power, but power over longer optical cables wouldsuffer from an "impedance-induced power drop," according to thereport. Intel declined to provide more detailed timing on when the newcables will arrive and how much they will cost. First-generationThunderbolt ports will, however, be compatible with the new opticalcables. Last week, the chipmaker indicated that it intends to support the PCI-Express 3.0 protocol. Thunderbolt currently works withPCI-Express 2.0 technology. PCIe 3.0 is capable of moving data at 8giga transfers per second, a step up from the 5 gigatransfers persecond speed of PCIe 2.0. Intel and Apple released Thunderbolt little more than a year ago with the unveiling of the Early 2011MacBook Pro. The technology couples Intel's work on a "Light Peak"optical connector with Apple's Mini DisplayPort standard to achievetwo channels of 10Gbps transfers in both directions,simultaneously. Apple added Thunderbolt to most of its Mac lineup throughout 2011.Available Thunderbolt accessories have remained relatively sparse,though. The company released a Thunderbolt Display last July and several external drive options ( 1 , 2 ) exist for the technology. Apple's official $49 Thunderbolt cable was released last June. Itmeasures 2 meters in length and can connect twoThunderbolt-equipped Macs. A subsequent teardown of the cable revealed that it implements transceivers at either end of the cable toimprove reliability when transferring data at high speeds.
