4K dual-head KVM extender transmitter

The Vertiv Avocent LV5520T-400 extends keyboard, video and mouse signals over CATx or fibre links. It supports dual 4096x2160 displays at 60Hz and provides four USB 2.0 ports plus analogue audio connections. The unit operates without drivers on all known operating systems and includes status LEDs for link monitoring.

Upgrade from single-head

This transmitter replaces older KVM extenders limited to one display or resolutions below 4K. The jump is worth it when a workstation requires two 4K outputs and USB 2.0 peripheral access at distance. It also adds a fibre SFP+ option for longer runs where CATx reach is insufficient.

Dual 4K video with USB 2.0 and audio headroom

The link handles two 4096x2160 streams at 60Hz using adaptive compression at 5Gb/s over CATx or 10Gb/s over fibre. USB 2.0 full-speed channels support keyboards, mice and typical HID devices. Bandwidth runs out with high-throughput USB 3.0 storage or uncompressed video workflows beyond the stated resolutions.

Questions about this item

What physical space and power connection does the LV5520T-400 transmitter need?

The transmitter measures 186 mm wide, 39 mm high and 148 mm deep, weighs 2.73 lbs and ships with a 12 VDC 18 W power supply that accepts 100–240 VAC at 47/63 Hz.

Which cable type and port should be used for the link to the receiver, and what common mistake should be avoided?

Connect either the RJ45 port for 5 Gb/s CATx cable or the SFP+ port for 10 Gb/s fiber; do not plug both at the same time or the link will not establish.

What ongoing maintenance does the transmitter require, and which component is most likely to need replacement first?

No scheduled maintenance is required; the external 12 VDC 18 W power supply is the only field-replaceable part and should be swapped if the unit loses power while the mains supply is confirmed good.
