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 singlemode 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 singlemode or multimode LC fiber optic cable.
oUsing singlemode 9-micron cable, extend to 6.21 miles (10kilometers).
oUsing multimode 50-micron OM3 (or better) cable, extend to 984 feet (300 meters).
Supports Ultra-HD 4Kx2K resolutions to 3840x2160 and 4096x2160 @30/50/60Hz YUV 4:4:4, HDTV resolutions to
1080p @120Hz, and up to 1920x1200 (WUXGA).
HDMI features supported:
oHDMI 2.0
o8-bit, 10-bit, and 12-bit Deep Color
oDolby TrueHD, DTS-HD Master Audio, Dolby Digital, Dolby Digital+, Dolby Atmos, LPCM 2/5.1/7.1CH, DTS 5.1,

oBandwidth up to 600 Mhz (18Gbps)
o3D (1080p @60Hz)
oHDR
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.
