Ars Technica’s researchers have taken a look and published a report, why the Thunderbolt cables are so expensive. Researchers have also found the technology behind Thunderbolt cables has improved which could help to reduce the price either at the end of this year or at the beginning of next year. Basically, an expensive semiconductor called silicon germanium which was been used to make Thunderbolt cables, that’s why its price is high.
John Mitchell, marketing manager of Intersil said that his company has a solution to the problem which is currently in the pipeline. The company will bring ‘Active Cable IC Solution for Thunderbolt Technology‘. The company Intersil assumes that Active Cable IC Solution for Thunderbolt Technology could be the only complete solution for the manufacturers who sell ICs for Thunderbolt. And it is expected that this technology could reduce the cost of Thanderbolt cable manufacturing process.
