Replacement Products

The DXLink HDMI Fiber Receiver features built-in SmartScale® Technology to deliver HDMI with HDCP that is perfectly scaled for each connected display automatically, eliminating the integration challenges that can occur when sources and displays have different optimal resolutions. It accepts audio and video over single mode fiber from up to 10 Km. Mount the low-profile DXLink Fiber Receiver behind a display or above a ceiling mounted projector.

Common Applications

The ideal solution for any destination display or projector designed into an Enova DGX integrated system that requires the distance capabilities and inherent security of fiber – or both; including campus-wide distribution of sources that are shared between classrooms, secure military applications, casinos, arenas and museums. Directly connect LCDs, plasmas and projectors using the HDMI output connection while delivering room audio via the stereo audio output.

  • HDCP Compliance Over Fiber – Transmit HDCP compliant video including HDMI up to 10 Km (over 6 miles)
  • Industry Leading Data Rate – DXLink is leading the way with an optical transport rate of 10 Gbps
  • SmartScale® Technology – Automatically responds to the display's declared EDID information and scales the video to the best resolution and video parameters for that display without manual setup; this prevents inferior video quality when sources are forced to lower resolutions to support the least capable display in the system
  • Secure and Isolated – Fiber inherently provides extra security and electrical isolation making it the transport method of choice for many mission-critical secure environments
  • Field Serviceable Fiber Modules – Easily remove and replace SFP modules in the field


*See Duplex models for bidirectional control over fiber. Simplex models do not support control transport over fiber (such as Ethernet, USB, IR, Serial Control or EDID); although when used as part of a complete Enova DGX solution, control can be provided if a supplemental independent network connection is used. See the "Instruction Manual – Enova DGX Digital Media Switchers" for details.
