Why Do We Need Optical Fiber Extenders?

An optical fiber extender is a signal extension device. When long distance direct connection cable does not match the transmission requirements, an optical fibre extender is used. This ensures that long-distance signals are transmitted with minimum attenuation. So what exactly is a fiber optic extender? What are some of the most common types of fiber optic extenders? Let’s have a look at this article together.

Why Do We Need Optical Fiber Extenders?

The optical fiber extender, as the name implies, is an extender that replaces traditional cable transmission medium.with optical fiber as the transmission medium.

Fiber optic extenders are signal extension devices. People use it when the long distance direct connection cable cannot match the transmission requirements. It is to ensure long-distance signal transmission with minimum attenuation.

There is a sending end and a receiving end in a fiber optic extender. The sending end converts the input signal into an optical signal, and the receiving end is responsible for converting the optical signal into the original signal, so it is generally used in pairs.

Comparatively, the optical fiber extenders have a longer transmission distance, a relatively stable signal which is not easily distorted, and anti-interference than the traditional network cable extender

In order to achieve the best quality of the signal, there are generally knobs for independent adjustment of gain or other parameters at the end of the independently powered device. Between the sending and receiving ends there can be a coaxial cable, twisted pair (network cable), or even optical fiber, etc., depending on the application of the device.

Types of Optical Fiber Extenders and How to Use?

  1. Ethernet Fiber Extender (Fiber Media Converter)

An Ethernet extender, is also known as media converter. It is used to obtain copper-to-fiber or fiber-to-fiber connections in metropolitan area network access and enterprise customer data transmission services. A media converter is a cost-effective and adaptable device in the context of network hardware, and it’s the most widely used type of media converter that’s also used as a transceiver. It transforms electrical signals from copper unshielded twisted pair (UTP) network cabling into light waves for fiber optic cabling. If the distance between two network devices is larger than the transmission distance of copper cables, then we need a fiber optic connection.

  1. Fibre Optic HDMIExtender

Fibre optic HDMI extender can be used for long-distance transmission of audio and video signals from high-definition devices without attenuation. There are two types of HDMI extenders. One transmits analog signals. The analog signal will be attenuated from the first meter out. The longer the transmission distance, the stronger the signal attenuation. If the transmitted signal is output to a large screen, the output picture cannot be seen at all. The other type of transmission is a digital signal, which consists of a sender and a receiver. The sender is responsible for signal acquisition and compression, and the receiver is responsible for signal decoding and port allocation.

  1. PON Extender

PON Extender is an optical transmission equipment which magnify and reshape signals during optical transmission process. It can significantly reduce OLT consumption while also increasing network transmission distance. People widely use PON Extender in many optical communication applications for long-distance transmission. Its benefits include tiny optical signal sizes, cost-effectiveness and safety, and ease of installation, among others.

  1. Fiber KVM Extender

Fiber KVM Extender is the extension of the user’s mouse (Mouse), keyboard (Keyboard), and monitor signal (Video). This extension is mainly for long-distance computer control, the image will have compression loss. The maximum distance that can be reached is 300 meters, and a resolution of 2048*[email protected]

  1. VGA Extender and DVI Extender

People use VGA extender and DVI extender is used for long-distance transmission of computer signals without attenuation. They have a transmitter and a receiver, which uses Cat5/5e/6 cables to extend signal.


People can use optical fiber extenders in outdoor large screen, security monitoring, subway station, control center, multimedia teaching and other fields.

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
