Search Tips...

Keyword Search
Our search engine uses any or all keywords typed in the text box to give you product search results.
For instance, typing in kvm will give you a broader set of results than kvm switch cables.

Note, however, that keywords in quotes are treated as a single phrase and will not be evaluated individually.

Booleans (AND, +, OR, NOT, -) are not supported.

Also, some keywords will not return results, and may automatically correct to a similar keyword.

Part Number Search Selection
Select this Search in the drop down box to search by part number instead of keywords.

Wild Card Search
The * character is only supported in a limited capacity. Using whole words is the best approach whenever possible.

"New Search" Radio Button
Search the entire section that you are currently in.

"Search Within Results" Radio Button
Enter keywords or a part number to limit your results within the previously searched results.


Other features

A list of all matching product categories or resources will appear in the upper left corner of the results page, when applicable, to help you further narrow your results, if you desire.

Use the "sort by" drop-down menu on the results page to sort by "most popular" and price (low to high or high to low)
in the store section.

  • Description

    ServSwitch Brand Fiber KVM Extender, II (Multimode)


    Quick Facts

  • Send data up to 400 meters (1312.3 ft.) over 50-µm multimode cable.
  • Provide resolution up to 1280 x 1024.
  • Because it uses fiber optic cable, this extender is perfect for industrial and high EMI/RFI environments.

  • Further Details

  • Rackmount in our 19" Rackmount Tray (RMK250A).
  • Support an optional local monitor, keyboard, and mouse user station.
  • Support multiple video standards: VGA, XGA, SVGA, and SXGA.
  • Compatible with PS/2 mice, two-button mice, three-button mice, wheel mice, trackballs, and more!

  • Extend a PS/2® computer's KVM and audio signals on two fibers up to 400 meters (1312.3 ft.) on multimode cable using just one PS/2 keyboard, PS/2 mouse, and VGA monitor.

    The ServSwitch Brand Fiber KVM Extender provides digital transmission of keyboard, video, mouse, and audio information on two fibers up to 400 meters (1312.3 ft.) on multimode cable.

    Top-quality video.
    Unlike most KVM extenders, which use analog signals, the ServSwitch Brand Fiber KVM Extender uses digital signals to maintain top image quality.

    The extender works by digitizing video output from a local CPU, then sending it across fiber optic cable to a remote unit, which converts it back to the original analog signal.

    Because the extender uses fiber optic cable, transmissions are immune from electrical interference from sources such as nearby machinery or fluorescent lights.

    Go for distance.
    The ServSwitch Brand Fiber KVM Extender uses fiber optic cable for extraordinary reach—up to 10 kilometers (6.2 miles) over single-mode fiber optic cable. Multimode fiber optic cable supports 220 meters (721.7 feet) over 62.5-µm cable or 400 meters (1312.3 feet) over 50-µm cable. Image quality is independent of cable length.

    Minimize fiber requirements.
    The digital video signal is transmitted serially over a single fiber at rates up to 1.5 Gbps. The extenders use the second fiber of the fiber pair to send remote mouse and keyboard information back to the local CPU.

    Because the extender only needs these two fibers for full operation compared to the five fibers some extenders need, you save money by running less cable.

    Wide compatibility.
    The extender supports many of the most common VGA-compatible video standards (DOS mode, VGA, XGA, SVGA, or SXGA) at resolutions up to 1280 x 1024 or output refresh rates up to 75 Hz.

    The extenders also support all common PS/2® style mice and pointing devices including two-button mice, three-button mice, wheel mice such as Microsoft® IntelliMouse®, trackballs, and more.

    Audio, too!
    In addition to the keyboard, video, and mouse information, the local unit can also digitize audio signals from a local CPU or other audio device and encode it into the digital information sent to the remote unit on the video fiber. The sound quality doesn’t approach high fidelity (it’s converted to monaural if it’s stereo), but it's more than adequate for system sounds such as alerts.

    Local and remote control.
    You can also connect an optional local user station (keyboard, monitor, and mouse only) to the local unit. The local unit passes video through to the local monitor and switches the keyboard and mouse. (The local user contends with the remote user for keyboard and mouse control of the CPU—once the active user station is idle for two seconds, the first user to type at the keyboard or move the mouse will be granted control.)
