Local KVM workstation
Sure you can use copper KVM extenders to access and control
a CPU from the next room or the next building. But what if you need to work with a CPU a half mile away, or if you need more security, or if you have to run cable right past a generator?
You need ServSwitch™ Fiber Optic KVM Extenders. They greatly extend the distance between a computer CPU and a keyboard, mouse, and
But with a fiber optic solution like the ServSwitch Fiber Optic KVM Extender, these concerns are a thing of the past. You can leave a CPU in a secured cabinet or data center while you operate it from a convenient remote user station.
Using at least three multimode fiber strands, the extender system can reach as far as 0.6 miles (1 km) on either
Each ServSwitch Fiber Optic KVM Extenderkit consists of two main components: a local module that you attach to an IBM® PC compatible CPU and a remote unit that you attach to the remote keyboard, monitor, and mouse console. We even offer a version for connecting stereo audio and serial devices, such as touch screens, to your KVM fiber optic extender setup.
And because the extenders support dual access, you can add a KVM console on the local end, too. That enables you to operate the PC from either the local or remote user station.
Or, if you prefer, you can use the local KVM ports to feed into a BLACK BOX®KVM switch.
The ServSwitch Fiber Optic KVM Extendersare compatible with
all standard keyboards and all standard
Locating a CPU away from your workstation has a number of advantages. For instance:
•In industrial applications, you can protect delicate server circuitry against dust, debris, moisture, and equipment vibration and keep data communications safe from potential interference (emitting from induction furnaces or current or load generators, for example).
•In environments where data security is the highest priority, you can protect against data theft and unauthorized installation of software.
•It also simplifies the setup, maintenance, configuration and administration of server management workstations.
In addition to industrial applications, ServSwitch Fiber Optic KVM Extenders can be deployed in:
•Call centers where you need to
•Retail or similar settings where you need to keep CPUs secure and apart from monitors in kiosks and digital signage displays, as well as user stations in publically accessible areas.
•Any application where you require remote access control of
No matter what their application, our compact KVM extenders feature an unobtrusive footprint, so you can set them up for operation in tight work spaces or data centers.

For monitoring operation, the remote module has a sevensegment display that continuously indicates link status. In addition,
Device Ready LEDs on both local and remote units inform you of their operational status, so you can troubleshoot at either end.
The ServSwitch Fiber Optic KVM Extenders support all
VGA graphics cards and VGA resolutions up to 1280 x 1024 @ 75
Hz. You can use them to transfer RGB as well as VGA (RGBVH) signals and, if necessary, convert signals to transfer RGB to VGA or from VGA to RGB. All you have to do is make a simple jumper adjustment on the extenders’ motherboards.
There’s no need to worry about the video getting horribly distorted at either end of the fiber optic link. By default, the KVM extenders operate with an automatic gain control (AGC) function enabled. With AGC enabled, the gain of each color signal is fixed to give colors the same white level (0.7 Vpp), and most video problems are cleaned up automatically.
In some applications, it may be necessary to switch off the AGC so you can optimize video (to remedy a chromatic aberration, for instance). For this, you just need to flip internal jumpers and tweak the manual brightness and contrast
potentiometer dials on the rear panel of each unit. You can also attenuate the optic budget to raise the optical loss to a value that corrects any unstable image. (To do this, you need fiber pigtail coupling connectors. For details, call our FREE Tech Support.)

For multimedia capability, connect a set of speakers or a headset or microphone to a workstation linked to the remote unit. The extenders transmit stereo audio bidirectionally and simultaneously across the fiber cable link. The extender local unit sends audio digitally (as part of a
