10G Dual Link Fiber KVM Extenders | 4K@60Hz 4:4:4 over Fiber
About 10G Dual-Link Fiber KVM Extenders
VigilLink's VLEX-DH10GF fiber extender pair delivers 4K@60Hz 4:4:4 video with KVM over dual-link 10G fiber optic cable — providing distance and EMI immunity that Cat cable HDBaseT extenders cannot match. Sold as a matched transmitter (VLEX-DH10GF-TX) and receiver (VLEX-DH10GF-RX) pair, this system is designed for installations where runs exceed HDBaseT limits, where fiber infrastructure already exists between locations, or where broadcast-grade electrical isolation is required between source and display environments.
Fiber transmission is inherently immune to electromagnetic interference from industrial equipment, RF systems, fluorescent ballasts, and high-voltage cabling, making the VLEX-DH10GF pair the preferred choice for broadcast control rooms, secure government facilities, healthcare, and manufacturing environments.
Choosing the Right 10G Fiber Extender
VLEX-DH10GF-TX (Transmitter): Connects to the HDMI source and KVM input devices at the local end, converting the signal to 10G dual-link fiber for transmission to the remote receiver. Install at the source rack, workstation, or AV head end.
VLEX-DH10GF-RX (Receiver): Connects to the remote HDMI display and local USB peripherals at the far end, reconstructing the full 4K@60Hz 4:4:4 signal from the fiber link. Install at the remote display location or operator workstation.
Frequently Asked Questions
What is a dual-link fiber KVM extender and how is it different from HDBaseT?
A dual-link fiber KVM extender transmits HDMI video, keyboard, video, and mouse signals over fiber optic cable rather than Cat copper cable. Fiber provides complete EMI immunity, supports longer cable runs with no distance-related signal degradation, and electrically isolates source and display — features that Cat cable HDBaseT cannot provide. The VLEX-DH10GF pair uses 10G dual-link fiber to deliver 4K@60Hz 4:4:4 with KVM.
What fiber cable type does the VLEX-DH10GF pair require?
The VLEX-DH10GF TX/RX pair uses IEEE 802.3ae-compatible SFP+ modules with dual-optical fiber (LC-style or pre-terminated crossover cable). With OM3 multi-mode fiber, the system reaches 300m; OM4 multi-mode reaches 550m; single-mode fiber extends to 30km. Both the transmitter and receiver must be fitted with matching SFP+ modules. Maximum transmission distance depends on the specific SFP+ modules used — consult VigilLink for module recommendations for your installation distance.
What KVM functionality is supported over the fiber link?
The VLEX-DH10GF pair extends keyboard, mouse, and USB-HID peripheral signals alongside HDMI video, allowing full workstation operation from the remote receiver location. This is suited to operator stations where the computing equipment must be in a separate locked or environmentally controlled room.
Can I use the VLEX-DH10GF-TX or VLEX-DH10GF-RX independently?
No. The VLEX-DH10GF-TX and VLEX-DH10GF-RX are a matched pair and must be used together to complete the fiber extension link. The transmitter converts HDMI and KVM to the fiber signal; the receiver reconstructs it at the remote end. Deploying only one unit does not create a functional extension.
What are the typical installation environments for 10G fiber KVM extenders?
Broadcast control rooms (where RF interference is present), secure government and defense facilities (requiring electrical isolation), healthcare facilities (infection-control compliance requiring rack-mounted workstations), manufacturing plants (high EMI from motors and variable frequency drives), and campus or multi-building AV systems where fiber already runs between buildings.
