What is a KVM fiber optic extender?
A KVM fiber optic extender is a device that uses optical fiber to transmit keyboard, video, and mouse (KVM) signals. It consists of a sending end and a receiving end, and is generally used in pairs. It allows users to operate computers as conveniently and quickly as they are in a local place far away from the computer.
The principle of KVM fiber optic extender
The main principle of the KVM fiber optic extender is that the sending end converts the video signal and USB signal of the computer host into an optical signal, and transmits the optical signal to the receiving end through the optical fiber, and the receiving end converts the optical signal back to the KVM signal, so that the remote Can normally connect the computer monitor, keyboard, mouse, and then operate the computer.
There are various types of KVM fiber optic extenders, which are mainly divided according to the distance to be extended, supported resolutions, interface types (such as DVI, HDMI, VGA, etc.), and whether they support additional functions such as USB, audio, and infrared return. Among them, the most common types are single-mode and multi-mode. Single-mode fiber extenders can support longer transmission distances, while multi-mode fiber extenders are relatively short, generally between 60 and 300 meters.
Common KVM fiber optic extenders mainly include HDMI KVM fiber optic extender (such as eKL-HE001, eKL-HFKU200, etc.), DVI KVM fiber optic extender (such as eKL-DFKU200), VGA KVM fiber optic extender (such as eKL-VFKU200).
KVM fiber optic extenders are widely used in various occasions that require remote operation of computers, including but not limited to:
Data Center: In a data center, servers are usually centralized in one place, while operators may be in another. Using KVM fiber optic extenders, operators can operate them away from the servers, without having to work in the server room, and at the same time can reduce the temperature of the computer room, thereby increasing the life of the equipment.
Broadcast and video production: In these areas, real-time monitoring and control of multiple video sources is required. The KVM fiber optic extender allows the operator to monitor and control far away from the video source, while maintaining the quality of the video signal.
Industrial Control: In many industrial environments, computers may be placed in harsh environments such as high temperature, high humidity, dust, etc. Using the KVM fiber optic extender, the operator can be isolated from these harsh environments without affecting the operation of the computer.
The following will take the KVM fiber extender eKL-HE001 as an example to show the interface and connection topology diagram of the fiber extender, so as to further facilitate everyone's understanding of this device.
