The New DH Labs Premium GLASS MASTER Toslink offers 300 strands of proprietary glass fibers and delivers the widest bandwidth & frequency response in the industry. Glass fiber optical cable is the highest quality digital optical cable medium available, with a significantly higher acceptance angle than standard plastic fiber. To transmit light with the precision of this cable, the fibers must contain glass of the highest purity. The process of making glass with this level of perfection is very demanding, requiring careful control over the materials and processes involved.

Final Testing includes:

• Refractive index profile
  
• Fiber geometry inspection, including core, cladding and coating
  
• Tensile strength
  
• Bandwidth capacity
  
• Attenuation at different wavelengths
  
• Chromatic dispersion & numerical aperture
  

We then add custom machined gold-plated connectors with precision-polished optical-grade lens surfaces at the connection points for reduced jitter. The combined result is the finest optical cable available at any price.
