About the FOX II T/R DP 4K Transmitter and Receiver
The FOX II T/R DP 4K Transmitter and Receiver are an ultra-high performance fiber optic
extender set for long haul transmission of HDCP-compliant DisplayPort video, audio, and
RS-232 and IR control signals over fiber optic cabling. The transmitter and receiver can
extend DisplayPort signals up to 30 km (18.75 miles) for the singlemode model (see
Cable Transmission Modes
Transmitter
The FOX II T DP 4K transmitter accepts DisplayPort video, at a resolution of up to 4K
(4096x2160 at 30 Hz). The video input can also include embedded audio. The transmitter
also loops the DisplayPort input through for a local monitor.
The transmitter can accept an analog audio input on either a 3.5 mm mini jack or a 5-pole
captive screw connector. The transmitter automatically detects whether embedded audio
is present on the DisplayPort input. If none is detected, the transmitter selects the analog
audio for the unit to embed in the digital video stream and transmit to the receiver. An SIS
command selects either audio.
The transmitter accepts a one-way (transmitter-to-receiver) RS-232 and IR communication
signal input (for applications such as projector control). The transmitter can receive an
optional return (receiver-to-transmitter) stream of serial RS-232 and IR communications from
a controlled device, such as projector responses.
The transmitter converts the DisplayPort video, the selected audio, and the RS-232 serial
communication into a proprietary data stream and outputs it as an optical signal via fiber
optic small form factor pluggable (SFP) modules on a single LC connector to a compatible,
Extron FOX II fiber optic receiver. It also can receive an audio return channel.
The transmitter has a built-in color bars test pattern to assist in setting up the display
equipment.
Receiver
The FOX II R DP 4K receiver accepts a proprietary optical signal on a single LC connector
from a compatible fiber optic transmitter. The receiver is compatible with all existing Extron
FOX II, FOX, FOXBOX, and PowerCage FOX VGA, DVI, and HDMI transmitters.
The receiver outputs DisplayPort video, digital audio (embedded in the DisplayPort output),
analog audio, and RS-232 and IR commands and data.
If the receiver is appropriately configured and has a second fiber optic cable installed, it also
can receive RS-232 and IR returns from controlled devices and send them to the transmitter
via a proprietary optical signal.
The video output of the receiver is a lossless DisplayPort image up to 4K
(4096x2160 at 30 Hz), including 1080p/60 with Deep Color.
Both Units
The transmitter and receiver have many controls, including audio adjustments, that are
available under RS-232 and USB port SIS control. Both units have video, audio, fiber light
status, and lost-light alarm indicators.
