Fibre interconnection and data room reference Published 08 May 2025

Use this reference to prepare product questions for FD SOLUCIONES. Check interfaces, capacity, protection and installation requirements against the current product documentation.

KVM fiber extenders allow secure, long-distance remote control of computers and servers with high-resolution video, USB, audio, and serial signal support. OverviewKVM fiber extenders transmit keyboard, video, mouse (KVM), audio, USB, and serial signals over optical fiber, enabling remote access to computers or servers without performance loss. They are ideal for high-EMI environments, secure server rooms, control centers, broadcast studios, medical facilities, and industrial applications.

Fiber optic transmission ensures EMI immunity, optical isolation, and long-distance connectivity ranging from hundreds of meters to tens of kilometers.

Key Features

Distance and Fiber Type: Multi-mode fiber: typically up to 550 meters (1,800 ft) for 4K video. Single-mode fiber: can extend signals up to 70 km (43 miles) depending on the model. Video Resolution Support: Supports resolutions up to 4K 60Hz (4: 4: 4) for HDMI, DisplayPort, DVI, or VGA.

Multi-monitor support available, e.g., dual or quad monitors over a single fiber cable. Signal Types: USB 2. 0/3.

0 for peripherals, HID devices, and touchscreens. Audio (stereo or two-way) and RS232/IR for serial control. Latency and Performance: Zero-latency or near-zero latency transmission ensures real-time control, critical for mission-critical applications.

Scalability and Integration: Some extenders support up to 16 transmitter-receiver pairs via a single Gigabit Ethernet switch. IP-based KVM extenders allow flexible deployment but may not support full matrix switching without specialized models. Security and Reliability: Optical fiber provides secure, hacker-resistant transmission.

Suitable for environments requiring continuous 24/7 operation.
