Introduction
The ST121HDFXA is a long-range HDMI® video extender kit that uses SC ber optic
cable to extend video / audio from an HDMI®-equipped device up to 2600 feet
(800 Meters) to a remote display. The extender supports full High-Denition video
(1920x1200 / 1080p), and includes both the transmitter and receiver, for a complete
ready-to-use digital signage solution.
Not only is this an incredibly long range solution that can extend an HDMI® signal
across or between buildings , but because ber optics transmit data using light rather
than copper, it will not cause or be eected by electromagnetic Interference (EMI).
For convenient, time-saving control of the media source, the HDMI® extender also
oers Infrared (IR) extension, which enables you to control the HDMI® audio-video
source from either end of the connection. The kit also includes optional mounting
hardware for a clean and professional installation.
The ST121HDFXA HDMI® over Fiber Optic Extender kit is backed by a StarTech.com
2-year warranty and free lifetime technical support.
