SFP+ Configurable DM Port
The “DM IN” port on the DMCF-RX-4K-SFP is configurable using SFP+
transceiver modules to enable compatibility with multimode or single-mode
fiber types.[2] Each DMCF-RX-4K-SFP is sold as a packaged kit containing
the receiver card and one SFP+ module as follows:
DMCF-RX-4K-SR PAK KIT – Supports duplex multimode fiber at up to
1000 ft (300 m) using OM3, or 1300 ft (400 m) using OM4
DMCF-RX-4K-BX PAK KIT – Supports simplex single-mode fiber at
up to 6.2 miles (10 km) using ITU-T G.652.D fiber, Crestron model
CRESFIBER8G-SM-P or equivalent
DMCF-RX-4K-S PAK KIT – Supports legacy CresFiber® 8G Multimode
fiber at up to 650 ft (200 m) (Only for retrofit applications where
Crestron CRESFIBER8G-NP or CRESFIBER8G-P is already installed;
not for new installations!)
>> Requires a DMF or DMCF series transmitter
The DMCF-RX-4K-SFP is a fiber-based receiver card designed to function
as part of a Crestron® 4K video signal extender solution. It is used with a
companion transmitter (DMF-TX-4K-SFP or DMCF-TX-4K-SFP [1]) to support
point-to-point signal extension, and may also be used to add 4K fiber input
capability to a DigitalMedia™ switcher (see “DM® Switcher Integration”
below for details) .
The DMCF-RX-4K-SFP installs in any slot of a DMF-CI-8 card chassis.[1]
Its “DM IN” port allows for the insertion of an appropriate SFP+ transceiver
module to enable compatibility with multimode or single-mode fiber.[2] It
also features a built-in 4K/60 scaler, HDMI® and analog audio outputs, a
local HDMI input, and a gigabit Ethernet LAN port.
4K Ultra HD
The DMCF-RX-4K-SFP enables uncompressed 4K/60 video signal
extension over fiber optic cable. Support for 4K video ensures support for
the latest generation of computers and monitors with native resolutions
beyond 1080p and WUXGA. The DMCF-RX-4K-SFP can handle
uncompressed Full HD 1080p, Ultra HD, 2K, and 4K video signals with
support for Deep Color and HDCP 2.2. Audio capabilities include support
for high-bitrate 7.1 audio formats like Dolby® TrueHD, Dolby Atmos®, and
DTS-HD Master Audio™ as well as uncompressed linear PCM.
DM® Switcher Integration
The DMCF-RX-4K-SFP works integrally with a DM-MD series matrix
switcher to facilitate routing of 4K video and control signals over fiber
optic cable. Setup requires simply installing the DMCF-RX-4K-SFP in a
DMF-CI-8 card chassis and connecting its HDMI output to an available
HDMI input on the switcher. An Ethernet LAN connection is also required to
enable communication with the associated control system.[3]
| 800.237.2041
Local HDMI® Input
In addition to its DM input port, the DMCF-RX-4K-SFP also includes an
HDMI input, which can be used to connect any HD or 4K source. Switching
between the DM and HDMI inputs can be done automatically using autoswitching mode or programmatically via a Crestron control system.
Analog Audio De-Embedding
A balanced analog audio output is included to allow stereo audio signals
to be extracted from the digital output and fed to a separate audio
switcher, processor, or amplifier. The output volume is adjustable via a
control system.[4]
4K/60 Scaler
Built-in Crestron 4K/60 scaling technology ensures that input sources
of any resolution or frame rate can be routed and displayed reliably. The
DMCF-RX-4K-SFP accepts any input resolution from standard definition
NTSC 480i to ultra high-definition DCI 4K, and scales it beautifully to any
output resolution up to DCI 4K (4096 x 2160 @ 60 Hz). Interlaced sources
are converted to progressive scan using motion-adaptive deinterlacing.
Intelligent frame rate conversion enables support for 24p and PAL format
sources. Fully automatic operation eliminates any complicated setup.
Dynamic Text Overlay
Dynamic text overlay capability allows for labeling of the video image, or
can be used to display instructions, schedules, alerts, or other messaging.

Gigabit LAN Connectivity
The DMCF-RX-4K-SFP includes a gigabit Ethernet port for integration
with a Crestron control system via the local network. Ethernet is also
transported over the fiber interface, eliminating the need for a separate
LAN connection at the transmitter, and allowing the transmitter’s LAN port
to be used to provide LAN connectivity for a local computer or
other device.[3]
DMCF-RX-4K-SFP provides a gateway for controlling devices through
their HDMI connections, potentially eliminating the need for any dedicated
control wires or IR emitters.
CEC Embedded Device Control
DigitalMedia offers an alternative to conventional RS-232 or IR control
methods by harnessing the CEC (Consumer Electronics Control) signal
embedded in HDMI. Through its connection to a control system, the
