History and vision

IX-CAD was founded in 2001 and offers products and engineering design services for high-speed digital applications for Fiber Optic communication.We have long lasting experience and unique Know How which has developed leading edge products over decades:

  • First 10Gbit/s TO-Header for SCHOTT Electronic Packaging in 2001
  • XFP Compliance Test Board kit in 2004
  • 40Gbit/s DQPSK system at CoreOptics (now Cisco) in 2007
  • 25Gbit/s TO-Header in 2009
  • TOSA and ROSA for 100Gbit Ethernet in 2011

With our engineering design services we bring RF and Fiber Optics expertise to small and midsize companies which don’t have the resources or can’t build it up.

Our product portfolio of test and measurement equipment supports companies to test their products for new upcoming markets.

SCHOTT Electronic Packaging – ix-cad GmbH Collaboration

SCHOTT and IX-CAD have a shared vision regarding the need of cost effective, hermetic sealed packages for very high speed applications in the Fiber Optics industry.

This collaboration leverages SCHOTT’s expertise in developing and manufacturing reliable, hermetic packages and combines that expertise with the advanced circuit and electromagnetic simulation capability from ix-cad. SCHOTT and ix-cad have defined a common design flow to achieve highest quality within short development time and with minimum use of resources.
