2. Introduction

2.1 Overview

There are many KVM extenders available, but until now many of them have used analog image transmission, which inherently degrades image quality (especially over long distances and at high video resolutions).

The ServSwitch™ Brand Fiber KVM Extender II and II-SM is a digital image- transmission system. Video output from a local computer CPU is automatically digitized by the Extender’s Local Unit and transmitted serially to the Remote Unit on a single fiber at data rates up to 1.5 Gbps. The Remote Unit converts the digital signal back into the original analog signal. Up to the maximum specified cable lengths, image quality is independent of cable length.

The Extender uses its second fiber to send remote mouse and keyboard information back to the local CPU. The Extender needs only these two fibers for full operation. Compared with some analog KVM extenders that require as many as five fibers, the Fiber KVM Extender II and II-SM can save you significant amounts of money, especially if you’ll need to run fiber cable across long distances.

There are two models of the Extender:

•The Fiber KVM Extender II (ACS250A) is the multimode model. It transmits digital video up to 220 m (720 ft.) across 62.5/125-µm multimode fiber or up to 400 m (1310 ft.) across multimode fiber.

•The Fiber KVM Extender II-SM (ACS251A) is the single-mode model. It transmits digital video up to 10 km (6.2 mi.) across 9/125-µm single-mode fiber.

In addition to the keyboard, video, and mouse information, the Local Unit can also digitize optional sound information 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 won’t approach high fidelity (it will be converted to monaural if it’s stereo), but will be roughly equivalent to that of sound transmitted over the telephone, which is sufficient for error messages and so forth.

You can also connect an optional local user station (keyboard, monitor, and mouse only) to the Local Unit. The Local Unit will pass video through to the local monitor and will switch the keyboard and mouse. (This means that the local user contends with the remote user for keyboard and mouse control of the CPU: Once the active user station is idle for 2 seconds, the first user to type at the keyboard or move the mouse will be granted control.)
