ATEN KX9970FR Review
The ATEN KX9970FR is the fiber-networked receiver counterpart to the KX9970FT, decoding 5K DisplayPort video at the remote end.
Buy this alongside the KX9970FT transmitter, not on its own, same price as its partner unit, which is typical for matched KVM-over-IP transmitter/receiver pairs.
The Remote Half of the Fiber Pair
The KX9970FR decodes the KX9970FT transmitter's 5K DisplayPort signal at the remote workstation, over the same fiber network connection, completing a matched pair built for facilities with fiber already run between rooms or racks.
Identical Pricing to Its Transmitter
Both halves of this pair are priced the same, which is common for ATEN's KX9970 line, unlike some vendors that price transmitters and receivers differently, budgeting for this pair is simply double the single-unit price.
Comparison to Alternatives
The copper-based KX9970R (also in this catalog) does the same 5K decoding job over standard Gigabit Ethernet instead of fiber, at the same price, choose based on your network backbone. Emerald's EMD4000R caps at 4K for a slightly lower cost.
