ATEN KX9970FT Review

The ATEN KX9970FT is a 5K DisplayPort KVM-over-IP transmitter with fiber network connectivity.

The 'F' marks the fiber-networked variant of ATEN's KX9970 series, pick this over the copper KX9970T if your building's KVM-over-IP backbone already runs fiber, since it costs the same but future-proofs longer network runs between racks.

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

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
