ATEN THE CE680 IS A DVI Optical KVM Extender That Overcomes Length Restrictions OF ST

ATEN CE680 DVI KVM Extender over Fiber Optic

Overview

The ATEN CE680 is a DVI KVM extender that transmits video, keyboard, and mouse signals over a single optical fiber — purpose-built for deployments where copper-based KVM runs have hit their distance ceiling. The CE680 operates as the remote unit in an ATEN fiber KVM extender pair, receiving DVI video and USB HID signals via a bidirectional SFP (LC) port running at 3.125 Gbps over single fiber. Maximum supported resolution is 1920 x 1200 @ 60 Hz (24-bit), covering standard HD and WUXGA displays without downscaling. The on-unit pushbutton wakeup lets operators bring a connected PC out of sleep without returning to the source. Use this unit anywhere the local/remote distance exceeds what a standard copper KVM extender can handle — control rooms, broadcast production suites, server rooms with remote operator stations, or security operations centers where the workstation must be physically separated from the display and input devices.

Compatibility

The CE680 is the remote (receiver) unit designed for use with the ATEN CE680/CE690 fiber KVM extender family. The paired local transmitter unit is the CE690. Both units communicate over the same bidirectional SFP LC interface. The LC SFP transceiver module governs fiber type and distance — single-mode or multimode reach depends on the SFP module installed. As part of the broader KVM extender product category, the CE680 connects to any DVI-D source via the local transmitter and supports standard USB HID peripherals (keyboard, mouse) at the remote end. Consult the ATEN CE680/CE690 user manual (ce680-690-user-manual-w.pdf, released 2025-12-17) for full pinout, SFP module compatibility, and supported fiber specifications before specifying cable plant. Firmware v3.1.309 (released 2025-10-15) is the current release.

Installation Notes

Humidity operating range is 0–80% RH non-condensing — avoid installations in high-moisture environments such as unventilated equipment closets or outdoor enclosures without appropriate climate control. Rack-mount form factor: ATEN notes that physical dimensions for rack-mount products may be expressed in LxWxH rather than standard WxDxH order — verify orientation in the datasheet before specifying rack space. The bidirectional SFP (LC) port on the CE680 requires a compatible SFP transceiver matched to your fiber plant; the transceiver is not included and must be specified separately based on fiber type and run length. Pair with a suitable ATEN KVM switch or source workstation at the transmitter end to complete the extension link.
