Black Box ServSwitch DVI-D USB KVM-over-Fiber Extender

Meet a premium KVM solution built for data centers, control rooms, and mission-critical server rooms. The Black Box ServSwitch DVI-D USB KVM-over-Fiber Extender is engineered to deliver crystal-clear DVI-D video, USB keyboard and mouse control, and reliable KVM switching over optical fiber. Designed to maximize distance without sacrificing image quality, this extender pushes the boundaries of remote workstation access, enabling administrators to manage systems from safe or convenient locations while preserving full, responsive user experiences. With compatibility for 1080p at longer ranges and 1080i at even greater distances, it’s a versatile choice for demanding IT environments that demand clarity, security, and scalability.

• Long-distance, high-fidelity video: Extend DVI-D video up to 1000 meters at 1080p with crisp, flicker-free imagery, perfect for data centers and control rooms where the operator workstation sits far from the host computer. For 1080i, reach up to 2000 meters, ensuring flexible deployment across large facilities while preserving sharp lines and color accuracy.

• Integrated USB KVM control: Transparent USB hub support lets you share keyboard and mouse across the extender pair, enabling seamless KVM access without sacrificing performance or reliability. It supports standard HID devices and keeps input latency to a minimum for responsive operation.

• Fiber-based security and isolation: By transmitting KVM signals over single-mode fiber, the system provides excellent EMI/RFI isolation, reduced risk of electrical interference, and enhanced security in environments with heavy electrical noise or sensitive equipment nearby.

• Robust, enterprise-ready design: Built for 24/7 operation in busy IT environments, the ServSwitch extender features durable enclosures and a footprint designed for rack-mount or shelf installation, delivering steady performance under demanding workloads.

• Plug-and-play deployment with scalable architecture: Designed for quick setup, this extender easily fits into existing KVM cascades or standalone configurations. Add additional units or cabinets to scale as your infrastructure grows, without compromising performance or manageability.

• Security and isolation: Fiber-based link provides strong electrical isolation and resilience against ground loops and electromagnetic disturbances, enhancing system reliability in sensitive installations.

how to install Black Box ServSwitch DVI-D USB KVM-over-Fiber Extender

• Plan your topology: Determine the host computer location (transmitter unit) and the display/console location (receiver unit). Verify fiber cable routes and workplace safety guidelines for cable routing and power access.
• Connect the video path: Attach the host computer’s DVI-D output to the transmitter’s DVI-D input. Connect the receiver’s DVI-D output to the display’s DVI-D input, ensuring clean, screw-capped connections for reliability.
• Establish USB control: Plug the USB keyboard and mouse into the transmitter’s USB ports or the designated USB pass-through ports, depending on your model variant. Confirm that the host system recognizes HID devices after setup.
• Link the fiber: Connect the single-mode fiber cable between the transmitter and receiver units. Use the correct connectors and follow the recommended alignment steps to minimize insertion loss.
• Power and test: Apply power to both transmitter and receiver units. Power-on the host and display, then test KVM control by moving the cursor, typing, and confirming video integrity across the extended distance. If needed, run basic resolution and color calibration to ensure optimal image quality.

Frequently asked questions

• What resolutions are supported by the extender? The system is designed to extend 1080p at 60 Hz up to 1000 meters and 1080i up to 2000 meters over single-mode fiber. For other resolutions, refer to official product documentation to confirm compatibility and performance over extended distances.
• How far can I extend DVI-D and USB signals? Up to 1000 meters for 1080p video and up to 2000 meters for 1080i video, with USB keyboard/mouse pass-through maintained across the fiber link.
• Is external power required? Yes. External power supplies are recommended for reliable operation of both the transmitter and receiver when deployed in a KVM-over-Fiber configuration.
• Does it support plug-and-play without drivers? Yes. The KVM-over-Fiber extender is designed to work with standard USB HID devices, offering driver-free usability for common keyboards and mice, while DVI-D video remains compatible with standard displays.
• Can I cascade or extend beyond the stated distances? While the extender is engineered for long-distance fiber links within the specified ranges, cascading multiple units typically requires a careful network design and may involve repeaters or additional hardware. Always refer to the official installation guide for recommended configurations.
• What environments is this extender suited for? Data centers, control rooms, industrial environments, campus facilities, and any application requiring secure, high-quality remote management of servers or workstations over fiber.
