ATEN KX9970FT Review

The ATEN KX9970FT is a DisplayPort 1.2 KVM-over-IP transmitter with fiber networking, supporting 5120x2880 @ 30Hz or 4K at 60Hz, with single-mode fiber reach listed to 10000 m.

This is the fiber transmitter for a single computer with one DisplayPort display. It supports up to 5120x2880 @ 30Hz, and drops to a smoother 60Hz at 4K, so the highest resolution comes with a low refresh rate. Control is by RS232 and LAN, with hotkey switching, audio and an extension reach of 10000 m over single-mode fiber. It needs external power and costs 2479.45. Because it is the transmitter only, you also need a matching receiver at the desk end. It makes sense where the building backbone already uses fiber.

Fiber Networking, Same 5K Resolution

The KX9970FT matches the standard KX9970T's 5K DisplayPort capability but connects over fiber rather than copper Gigabit Ethernet, useful in facilities where the KVM-over-IP backbone already runs fiber between equipment rooms.

Choosing Fiber vs. Copper

Fiber buys distance and immunity to electrical interference over a standard copper network run, at the cost of needing fiber-capable network switches; if your infrastructure is already copper-only, the standard KX9970T (also in this catalog) does the identical job for the same price.

Comparison to Alternatives

Emerald's EMD4000T (also in this catalog) tops out at 4K DisplayPort over standard copper Ethernet for a slightly lower price, a reasonable step-down if 5K resolution and fiber aren't required. The matching KX9970FR receiver is required to complete this transmitter's link.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Expert rating8 / 10

A strong 5K DisplayPort transmitter for fiber-backed IP KVM infrastructure, pick the copper KX9970T instead if your network doesn't run fiber.

Best for

Facilities with an existing fiber KVM-over-IP network backbone
5K DisplayPort workstations needing long-distance network extension
Data centers standardizing on ATEN's KX9970 series

Not for

Copper-only network infrastructure, where the KX9970T is the right pick
Buyers without a matching KX9970FR fiber receiver
4K-or-lower resolution needs better served by the cheaper Emerald 4K line
