Rose CRK-2DFSUD2D Review

Rose CRK-2DFSUD2D dual-head DVI single-mode fiber KVM extender, up to 10 km, 1920x1200 per head.

Part of Rose's CrystalView DVI Fiber line: a dual-head DVI and USB extender over single-mode fiber, reaching up to 10 km, with a local port so the computer can also be used at its own end.

DVI Over Fiber

The unit carries two DVI heads plus USB over single-mode fiber, up to 10 km, far beyond what copper CATx extenders reach.

Comparison to Alternatives

Versus Rose's CrystalView HDMI and DisplayPort fiber extenders (CRK-2DTX series), this is the DVI option at 1920x1200 per head; pick the HDMI or DisplayPort models for 4K.
