The developement of AfterDark. Project Constellation FIBER Black Modernize SFP Network Card 

AfterDark. is looking for solution on best sounding for audiophile. The new collection is introduced - Project Constellation FIBER. The inspiration for the Project Constellaton FIBER Collection comes from the abstract of early developemt with the use of optical fiber, SFP Modules to enhance the listening and sounding for audiophile.  The optical isolation was motivated by some of the innovative ideas to eliminated the physical EMI noise and reproduce the music in more density with details.  

Today, AfterDark. has become an innovative design force, as it did at the beginning, a stimulating opportunity, the place where research and experimenting give life to precision devices that reflect my idea of Black Modernize design, exotic and essential material, to enhancing soundings. 


Based on the Intel 1GbE network controller I350, this SFP Adaptor addresses the demanding needs of the next-generation music server by providing unmatched features, and flexibility for LAN and Roon RAAT networking, and proven reliable performance. 

We would like to introduce the best compatible for Finisar SFP modules, this is certified to work well for Audio Server or Roon Server. This Ethernet Card is one of the very best SFP card which only generate moderated heat with custom made of  block of heat sink. Which is one of the important factor for Music Servers.    

Why we choose Intel I350 Network Adaptor ?

  • Build with Intel I350 v2 Chipset,
  • The Black Modernize Edition will optimised the firmware inside the BIOS is compatible with most SFP for Audio Application, Intel QuickData Technology, universal SFP port for best compatibility.
