About Dual-Head 10G Fiber KVM Extenders
VigilLink's VLEX-DH10GF series delivers dual-head 4K@60Hz 4:4:4 video and USB 2.0 keyboard/mouse extension over a single 10G SFP+ fiber link — enabling remote workstation operation at distances that are impractical or impossible with copper HDMI or USB cabling. The VLEX-DH10GF-TX transmitter connects to the host computer's dual HDMI outputs and USB ports at the source end; the VLEX-DH10GF-RX receiver connects to the two monitors and USB peripherals at the operator console. Together, they form a complete point-to-point KVM extension solution that carries full-bandwidth, uncompressed 4K@60Hz 4:4:4 on both video channels simultaneously, along with bidirectional USB 2.0 for keyboard, mouse, and supported peripherals.
The 10G fiber backbone supports both multimode fiber (up to 300 meters) and single-mode fiber (up to 10 kilometers or beyond depending on SFP+ module selection), making the VLEX-DH10GF-TX/RX pair applicable to everything from cross-building secure server room installations to campus-scale and broadcast facility deployments.
Choosing the Right 10G Fiber KVM Extender Configuration
VLEX-DH10GF-TX (Transmitter): Installed at the host computer location. Connects to the source computer's two HDMI video outputs and USB host port, then transmits both video channels and USB data over the 10G SFP+ fiber link to the receiver. Required at the computer/server end of every VLEX-DH10GF installation.
VLEX-DH10GF-RX (Receiver): Installed at the operator console location. Receives the dual 4K@60Hz 4:4:4 video and USB data from the transmitter over fiber, then outputs to two HDMI monitors and accepts USB keyboard and mouse from the operator. Required at the display/peripheral end of every VLEX-DH10GF installation.
SFP+ Fiber Module Selection: The VLEX-DH10GF-TX and VLEX-DH10GF-RX accept standard 10G SFP+ optical modules (sold separately). For distances up to 300 meters, standard 850nm multimode SFP+ modules are used. For campus or facility-scale distances to 10 kilometers, 1310nm single-mode SFP+ modules are used. Confirm the fiber type installed in the facility before specifying SFP+ modules.
Frequently Asked Questions
What is a dual-head fiber KVM extender?
A dual-head fiber KVM extender carries two independent video signals — plus keyboard and mouse control — from a host computer to a remote operator console over a fiber optic link. "Dual-head" means both video outputs of a dual-monitor workstation are extended simultaneously over the fiber, so the operator sees both screens and has full keyboard/mouse control at the remote position.
How far can the VLEX-DH10GF extend over fiber?
Distance depends on the SFP+ optical module installed. Multimode fiber with standard 850nm 10G SFP+ modules supports up to 300 meters. Single-mode fiber with 1310nm SFP+ modules extends to 10 kilometers. For distances beyond 10 kilometers, consult VigilLink with specific site requirements. SFP+ modules are sold separately and must match the fiber type installed.
Does the VLEX-DH10GF transmit compressed or uncompressed video?
The VLEX-DH10GF transmits uncompressed 4K@60Hz 4:4:4 video on both channels simultaneously over the 10G fiber link. There is no video compression, frame dropping, or color subsampling — the signal arriving at the receiver is bit-for-bit identical to the source output. This is essential for color-critical work in broadcast, post-production, and medical imaging applications.
What USB devices work over the VLEX-DH10GF USB extension?
The VLEX-DH10GF supports USB 2.0 HID devices — keyboard and mouse — over the fiber link in both directions. USB 2.0 bandwidth supports most standard peripherals, though high-bandwidth USB devices such as external storage drives may not be supported depending on the specific product revision. Verify USB compatibility for non-HID peripherals in the individual product documentation.
Can I combine the VLEX-DH10GF with a KVM switcher to extend multiple computers?
Yes. Placing a VigilLink KVM switcher (such as the VLKV-H2041 or VLKV-H202D) upstream of the VLEX-DH10GF-TX transmitter allows the operator at the remote console to switch between multiple computers over the fiber link. The KVM switcher selects the active computer source, and the VLEX-DH10GF carries that source's dual-monitor video and USB to the remote operator position.
