HDMI Over Fiber Converter | 4K KVM Extender up to 80km

Our HDMI over fiber converter series is designed for professional AV, broadcast, industrial control, and medical imaging applications. Unlike traditional copper HDMI cables, fiber optic technology enables uncompressed 4K@60Hz 4:4:4 video transmission over distances up to 300 meters (OM4 multimode) or even 80 kilometers (single-mode fiber).

These fiber optic HDMI extenders support KVM (keyboard & mouse), USB HID, bidirectional audio, RS232/485, IR control, and 10/100M Ethernet on select models. They are fully compliant with HDMI 2.0, HDCP 2.2, and offer plug-and-play installation with no driver or software configuration required.

Whether you need a mini 4K HDMI fiber extender for a conference room or a rugged KVM over fiber solution for a control center, our product line delivers zero-latency, interference-free, and future-proof signal extension.

Frequently Asked Questions

What is the maximum distance of HDMI over fiber?
Depending on the model and fiber type, our HDMI over fiber converters support up to 300 meters over OM4 multimode fiber (e.g., LNK-109KVM, LNK-109M) and up to 80 kilometers over single-mode fiber (e.g., LNK-MH4K-80, LNK-MHRA4K). Some models like LNK-108M reach 500m with OM5 fiber.
Do these fiber extenders support 4K@60Hz 4:4:4?
Yes, models like LNK-109KVM, LNK-109M, and LNK-4KH-1D1U1E1A1R support uncompressed 4K@60Hz with 4:4:4 chroma sampling. LNK-MH4K-80 supports 4K@60Hz 4:2:0 and 4K@30Hz 4:4:4; LNK-MHRA4K supports 4K@60Hz 4:2:0 and 4K@30Hz 4:4:4.
Do I need to install drivers for HDMI over fiber KVM?
No, all our HDMI over fiber converters are plug-and-play. No software or drivers are required for video, KVM, audio, or RS232 extension. Just connect the fibers and power up.
Can I use multimode fiber like OM3 or OM4?
Absolutely. Most of our models support OM3, OM4, OM5 multimode fiber with LC duplex or simplex connectors. Single-mode fiber (SMF) is used for long-distance models like LNK-4KH-1D1U1E1A1R, LNK-MH4K-80, LNK-MHRA4K, and LNK-KVM-HDMI-1D1BA1GO.
What’s the difference between KVM and non-KVM extenders?
KVM models (LNK-109KVM, LNK-4KH-1D1U1E1A1R, LNK-KVM-HDMI-1D1BA1GO) include USB ports for keyboard/mouse extension, allowing remote computer control. Non-KVM models (LNK-109M, LNK-108M, LNK-MH4K-80, LNK-MHRA4K) are pure video and audio extenders. Choose based on whether you need remote peripheral interaction.
