## Long description

The StarTech FD121‑KVM‑EXTENDER is a fiber optic DisplayPort KVM extender kit that includes both transmitter and receiver. It extends DisplayPort video and USB HID signals over multimode fiber up to 300 m (984 ft) using pre‑installed SFP+ modules, supporting UHD resolutions up to 3840×2160 at 60 Hz (4:4:4). The compact black steel units provide point‑to‑point extension without the need for drivers or network configuration, making them suitable for remote console extension, control rooms and AV installations requiring low‑latency, high‑quality video and peripheral connectivity.
Advantages
This KVM extender delivers full 4K@60Hz DisplayPort video with EDID pass‑through to preserve optimal display compatibility and color sampling. The built‑in USB HID interfaces offer three ports for keyboard, mouse and other input devices, enabling remote control of a host system or KVM switch. The fiber connection reduces electromagnetic interference and supports stable, long‑distance transmission. The units accept a wide AC input and provide a 5 V adapter output, while the rugged steel housing supports reliable installation in professional environments.
Suitable for
Remote console extension for control rooms and server racks
AV installations and digital signage requiring 4K video over long distances
Workstations that need centralised PC control with keyboard and mouse at a remote desk
Environments with high EMI where fiber reduces interference
Point‑to‑point links between KVM switches, consoles and PCs
Key specifications

How to use
Install the transmitter at the source device and connect its DisplayPort output and USB ports to the host or KVM switch. Install the receiver at the remote console and connect its DisplayPort output to the display and USB ports to the keyboard and mouse. Connect the transmitter and receiver with multimode fiber and the pre‑installed SFP+ modules. Power both units using the included power adapters. The extender operates point‑to‑point without drivers; EDID pass‑through preserves display settings automatically. If needed, replace the SFP+ modules with compatible MSA‑compliant modules for different fiber types or extended range.
Usage recommendations
For best performance, use certified multimode fiber and maintain clean SFP+ module endfaces. Verify DisplayPort cable quality from source to transmitter and from receiver to monitor. When deploying in high‑density or industrial environments, allow adequate ventilation around the steel enclosures and route fiber runs away from sharp bends to preserve signal integrity.
