Key Features
- Up to 20km (12.4 miles) over a single LC single‑mode fiber cable. Unlike copper extenders, our fiber solution maintains pure 4K video and USB 2.0 signals with zero degradation, no electromagnetic interference, and virtually no latency – perfect for campuses, data centers, and industrial sites
- It is plug‑and‑play – no drivers, no software, no network configuration. The transmitter and receiver auto‑pair as soon as they are powered on. Works with Windows, macOS, Linux, and any other OS that supports standard USB and DVI
- You can connect a keyboard, mouse, USB flash drive, printer, touchscreen, camera, or card reader. The extender transparently passes USB signals from your local console to the remote computer as if they were plugged in directly. All 4 ports are USB 2.0 (up to 480 Mbps)
- It transmits audio via the DVI channel (if your source supports DVI audio) or a dedicated 3.5mm jack. It also includes RS232 and IR pass‑through for controlling industrial equipment, PTZ cameras, projectors, or set‑top boxes
- Data centers, command centers, medical imaging, broadcast, home office. Unlike copper KVMs (max 400 ft), fiber provides 20 km range, zero latency, uncompressed 4K, and EMI immunity.
