The DMCF-TX-4K-SFP is a fiber-based transmitter card designed to function as part of a Crestron® 4K video signal extender solution. It is used with a companion receiver (DMF-RMC-4K-SFP or DMCF-RX-4K-SFP ) 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-TX-4K-SFP installs in any slot of a DMF-CI-8 card chassis. Its “DM OUT” port allows for the insertion of an appropriate SFP+ transceiver module to enable compatibility with multimode or single-mode fiber. It also features two HDMI® inputs, one analog audio input, a local HDMI output, and a gigabit Ethernet LAN port.
4K Ultra HD
The DMCF-TX-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-TX-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-TX-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-TX-4K-SFP in a DMF-CI-8 card chassis and connecting its first HDMI input to an available HDMI output on the switcher. An Ethernet LAN connection is also required to enable communication with the associated control system.
SFP+ Configurable DM Port
The “DM OUT” port on the DMCF-TX-4K-SFP is configurable using SFP+ transceiver modules to enable compatibility with multimode or single-mode fiber types. Each DMCF-TX-4K-SFP is sold as a packaged kit containing the transmitter card and one SFP+ module as follows:
- DMCF-TX-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-TX-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-TX-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!)
2x1 HDMI® Auto-Switcher
The DMCF-TX-4K-SFP includes two HDMI inputs for the connection of HD and 4K sources. Switching between the HDMI inputs can be performed automatically using auto-switching mode or programmatically via a Crestron control system.
Analog Audio Embedding
A balanced analog audio input is also included to allow a stereo audio source to be connected and combined with the video signal from either of the HDMI inputs. The analog audio input can be configured to be selected automatically if a digital audio signal is not detected on the active HDMI input.
Local HDMI Output
In addition to its DM output port, the DMCF-TX-4K-SFP also includes an HDMI output to allow the selected video and audio input signals to be fed to a local display or monitor.
Gigabit LAN Connectivity
The DMCF-TX-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 receiver, and allowing the receiver’s LAN port to be used to provide LAN connectivity for the connected display device or some other device.
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 DMCF-TX-4K-SFP provides a gateway for controlling devices through their HDMI connections, potentially eliminating the need for any dedicated control wires or IR emitters.
