The 4K HDMI over fiberTransmitter and receiver with return IR or RS232 or RS485


The 4K HDMI over fiber extender is a cutting-edge device designed to extend high-definition video and audio signals over long distances using fiber optic cables. With its advanced technology, it supports a maximum resolution of 40962160 at 30Hz, delivering stunning 4K visual quality for an immersive viewing experience.

This extender utilizes fiber optic cables for signal transmission, which offer several advantages over traditional copper cables. Fiber optic cables provide superior signal integrity, ensuring high-quality transmission without degradation over long distances. They are also immune to electromagnetic interference, making them ideal for installations in environments with high interference.

The HDMI over fiber extender is equipped with IR (Infrared) or RS232 or RS485 control options, allowing you to remotely control the connected HDMI video source. The IR control enables you to use a remote control to manage the source device, while the RS232/RS485 control offers serial communication for more advanced control applications. This flexibility provides convenient and seamless operation, especially when the video source is not easily accessible.

This extender is highly versatile and can be used in various real-life applications. It is suitable for extending HDMI signals between different devices, such as connecting a DVD player to a television, transmitting video from a computer to a projector, or even linking gaming consoles to a monitor. Its compatibility with a wide range of HDMI video source devices makes it a valuable tool in various professional and home entertainment setups.

Setting up the HDMI over fiber extender is straightforward. Simply connect the HDMI video source to the extender unit using a standard HDMI cable, and then connect the extender to the display device using a fiber optic cable. The extender handles the signal transmission, ensuring seamless and reliable video and audio delivery between the source and display devices.

The unit is equipped with a 10Gbps SFP+ and allows for the transparent transmission of 4K video and audio without any compression or encoding between the transmitter and receiver. The transmission is nearly instantaneous, with a delay of approximately 1ms

Question and Answers

There are several ways to do this.

If the latency is important in this case, You can use our HDMI over
fiber TX's and RX's , this is equivalent to PALKV378A-4.0.TX /

This is the link to the devices you could use:

It you can tolerate 1 second delay, you can use something different :

8-24ch IP video encoders ast a TX side and IP STB as decoders.

IP STB decoder:

The advantage is that in this case, you do not need to have a fiber
network; you can use a standard IP copper LAN for video distribution
from point to multipoint. The encoders will produce 8 to 24 individual
multicast streams, and IP STBs can receive them anywhere on the
