Update: The cable has made its way on to the online US Apple Store and it is indeed US$49.

Following yesterday’s Thunderbolt firmware update that brought “performance and stability fixes”, Apple has released the ‘Apple Thunderbolt cable’ that allows users to connect and daisy chain multiple Thunderbolt capable devices. The 2m long accessory is simply a cable that features the Thunderbolt connector on both ends. It is priced at $55 in Australia, £39.00 in the UK but has not yet made it into the US Apple Store – although based on similarly priced accessories it will be roughly US$49.

Thunderbolt technology supports blazing-fast data transfer with two independent channels of 10Gbit/s each. Use the Apple Thunderbolt cable to connect your Thunderbolt-equipped peripherals to your new iMac or new MacBook Pro.

As explained in our Thunderbolt editorial a few months ago, the Thunderbolt specification works by daisy chaining multiple devices together – allowing just one cable from the Mac to actually connect a number of devices together. This Thunderbolt accessory cable is that cable that can connect multiple Thunderbolt capable devices together.

The other piece of Thunderbolt news is that Sony has announced details of its new 13.1-inch VAIO Z that features Thunderbolt, except they are calling it Light Peak (the old name of the specification). Interestingly it features a ‘Power Media Dock’ that includes an external GPU and optical drive – all connected by Light Peak. It is certainly an interesting use of the Thunderbolt specification, and with its speeds that external GPU will certainly make that laptop much more powerful when connected.
