    Transparent optical cable low noise vs copper cable specifications and models

    Compare copper and active optical cables for high speed data connections, including differences in distance, signal integrity, power use, and deployment scenarios. Precision geometry controls noise and helps Transparent consistently create audio cables with our desired electrical characteristics. It is the key difference between Transparent and the many audio cables that are available that are merely off-the shelf designs with a brand name printed on. Direct Attach Copper (DAC) and shielded internal cables like SlimSAS and HD MiniSAS use conductive metal (usually copper) to transmit data over relatively short distances. Passive cables are restricted by their conductivity and can only carry a certain amount. When using a totally transparent cable it becomes apparent even for a none technical person that its only fiber and light that is used. The core distinction between the two technologies lies in the physics of data transmission.
