DST-75 V2

The cost-effective 75Ω digital transmission cable


DST-75R V2" is a 75Ω coaxial digital RCA cable with extremely low dielectric loss by "Cordell structure".

The "Cordell structure" is an insulation method that is as close as possible to air insulation, the ideal form of high-frequency transmission, and has a structure in which the center conductor is supported by PE cord wrapped around it in a spiral shape and an air layer is provided around the center conductor.

The center conductor and braided shield are made of "102SSC", a precision conductor of which Oyaide Elec is proud. Oyaide's specialties are incorporated throughout the cable, including a flex PE sheath for both electrical characteristics and flexibility, a copper foil shield with a 100% shielding ratio, and double shielding with a braided shield with a 90% shielding ratio.

As a high cost-performance digital transmission cable, this cable demonstrates its performance to the fullest in the transmission of S/PDIF coaxial digital and composite video for TVs and other devices.


Cordell structure

DST-75R V2" is a refined model based on the first generation DST-75R, with the conductor changed from PCOCC-A to the precision conductor "102SSC".

The structure is inherited from the first generation DST-75R. In other words, it is a 75Ω coaxial cable with extremely low dielectric loss due to the insulation.

The most distinctive feature is the "Cordell structure. This structure consists of a polyethylene cord between the center conductor and the polyethylene tube, with an air layer between the cord and the inclusions.

This results in an ultra-low-loss coaxial cable with extremely low dielectric loss due to the insulation.

Precision conductor ”102SSC”

DST-75R V2 uses the precision conductor 102SSC for the center conductor and braided shield.

  • The 102SSC precision conductor is made of virgin copper only, which does not contain any recycled copper, in accordance with JIS C1011, in order to avoid impurities as much as possible.
  • The peeling process removes 100% of impurities from the surface. To ensure smooth flow of electrical signals through the conductor surface layer, wires are thinned with a natural diamond die to improve the surface smoothness of the strands.
  • Fine wire strands are processed with a processing accuracy of ±1μm, far better than the standard error tolerance of ±8μm.
  • Annealing process twice eliminates mechanical stress distortion of strands. Thorough product control of manufacturing control values, maintenance, and number of shipping days. The conductivity is 102.3% IACS, which is the highest class.
