INTRODUCTION

The XTENDEX® 4K 18Gbps HDMI Extender via Fiber Optic Cable locates an Ultra-HD 4Kx2K 60Hz 4:4:4 HDMI display, IR, stereo audio, and RS232 up to 6.21 miles (10 km) away from a 4K HDMI source using a single LC singlehood fiber optic strand and 984 feet (300 meters) using OM3 multimode fiber optic cable. Each extender consists of a transmitter that connects to an HDMI source and a local display via the HDMI loop output, and a receiver that connects to an HDMI display.
Features

• Signal transmission via single-strand singlehood or multimode LC fiber optic cable.
  o Using singlehood 9-micron cable, extend to 6.21 miles (10kilometers).
  o Using multimode 50-micron OM3 (or better) cable, extend to 984 feet (300 meters).

• Supports Ultra-HD 4Kx2K resolutions to 3840×2160 and 4096×2160 @30/50/60Hz YUV 4:4:4, HDTV resolutions to 1080p @120Hz, and up to 1920×1200 (WUXGA).

• HDMI features supported:
  o HDMI 2.0
  o 8-bit, 10-bit, and 12-bit Deep Color
  o Dolby Trued, DTS-HD Master Audio, Dolby Digital, Dolby Digital+, Dolby Atmos, LPCM 2/5.1/7.1CH, DTS 5.1, and DTS:X
  o YUV 4:4:4, 4:2:2, and RGB
  o Bandwidth up to 600 Mhz (18Gbps)
  o 3D (1080p @60Hz)
  o HDR

• HDCP 2.2 and 1.4 compliant.

• Supports local and remote HDMI displays.

• Supports audio embedding and de-embedding.
  o Use the switch on the transmitter to select HDMI digital audio or analog stereo audio source.

  • Simultaneously outputs both HDMI digital audio and analog stereo audio.
  • When HDMI audio is selected, the extender passes the embedded digital audio to the HDMI connector and also converts/de-embeds the digital signal to analog stereo audio.
  • When LINE audio is selected, the extender passes the analog stereo audio to the 3.5mm analog audio connector and also converts/embeds the analog signal to digital audio.

• Bi-directional IR control from input and output locations.

• Support full-duplex RS232 up to 115200 baud.

• Plug-and-play functionality – no software needed.

• Low RFI/EMI for sensitive applications.

• Cables can be installed in conduit prior to extender installation.

• Integrated mounting brackets for easy surface/wall mounting.
