Manipulating Computers Within Your KVM Network

Posted by admin on January 15, 2016 11:52 am

A Keyboard, Video and Mouse (KVM) switch is a hardware device or devices that connect a keyboard and mouse at a local workstation to multiple computers and/or displays over a network, allowing the user to choose the source video and which monitor to send it to using remote access. KVM switches are useful for managing numerous servers within a single data center and accessing supporting terminals at both sides of the connection.

With KVM, it’s either a 1-to-1 (“1:1”) scenario, where you control a single source video to a single display, or one-to-many or many-to-many. In a 1:1 scenario, a user is able to choose a single input source video and a computer and/or display to send it to.

A KVM matrix switch serves as a central point for multiple video inputs and multiple connected computers and displays. For one-to-many or many-to-many scenarios, Opticomm-EMCORE offers the GXD matrix switch, which acts as a KVM switch and much more. It offers bidirectional signal distribution, routes any signal to any screen, and can switch all signal types including HDMI with HDCP, Display Port, DVI, VGA, Component and 3G HD-SDI, along with analog and digital audio. It can convert analog and digital signals, which can be transmitted via singlemode or multimode Fiber, CATx/HDBaseT or IP/Ethernet.

GXD switching and extension system is a true, non-blocking matrix that overcomes the potential blocking effects of grid lines in a matrix of several smaller KVM switches, as well as adverse performance effects experienced when connecting multiple KVM-over-IP switches using a backbone link of limited bandwidth. GXD’s massive 40 Gbps backplane accommodates real-time switching of uncompressed 4K resolutions now and 8K in the future, allowing it to serve as a staple for Installers that want a flexible and reliable connectivity platform.

GXD is modular, allowing the user to build the switch to their signal requirements and is scalable from 16×16 to 32×32. Additional notable features include the ability to break-away and switch audio separately, embed and de-embed audio into digital video signals, and preview any connected video source on the front touch-screen panel, eliminating the need for a local and dedicated monitor. It has redundant power and hot-swappable modules for full service and field upgrades without interrupting signal flow.

Opticomm-EMCORE is soon releasing the “4-channel multiviewer with scaling” insert card for GXD. The switch itself can route images to displays, but the multiviewer goes one step further and routes any of these inputs onto a single screen. It can create 4 individual images from any of the input sources onto a single display, built-in as part of the switching apparatus instead of using an external processor. Instead of needing to view an application on 4 separate computers, the viewer will see a representative of each of the 4 screens on a single display.

If the GXD matrix switch has too much power for your needs, Opticomm-EMCORE has other KVM solution options, including the following Optiva system cards, GBOX, and encoder/decoders. As example scenario, a command and control room typically has multiple computers connected to several displays on the wall.


Each computer may be connected to a rack that includes, depending on the graphics card in the computer (DVI or HDMI) and infrastructure employed (fiber or copper), one of the following Optiva system insert cards. Each transmitter card sends a different source of video to a set of displays at each station. Incidentally, all of these cards are also compatible with the GXD switch for even greater flexibility.

  • manipulating_computers_image_3.pngOTP-1HDMI2A-USB-ETH transmitter card for HDMI with Ethernet and USB KVM for fiber transport.
  • OTC-HDMI2A-USB-ETH transmitter card for HDMI with Ethernet and USB KVM for CATx/HDBaseT transport.
  • OTP-1DVI2A1UKM (optional 4K or 1080P) transmitter cards for DVI with USB KVM for fiber transport.
  • Coming soon! DisplayPort/HDMI transmitter card.

If you would rather not have a rack-based system and are using HDMI, you can use a GBOX throw-down box instead. GBOX is also compatible with the GXD switch.

  • GBX-F-HDMI-VGA transmitter box for HDMI, VGA or Component video with Ethernet and USB KVM for fiber transport.

Alternatively, if you are using video-over-IP, Opticomm-EMCORE offers several models of encoder/decoder pairs for an Ethernet LAN infrastructure, depending on your requirements.

  • NV Series for DVI, VGA, HDMI with HDCP (with adaptor) – data rate is variable from 20 to 800 mb/sec. For lossless, ultra-low latency transmission, 100 Mbps transmission is required, so a 1GB network is needed to operate on.
  • Eclipse Series for HDMI – visually lossless compression at 150 Mbps fixed data rate.
