Unlock Superior Visuals: 4K HDMI 2.0 for All Applications

The E-link LNK-109M mini 4K HDMI Fiber Extender is a single-core multi mode fiber extender specifically designed for long-distance 4K HDMI 2.0 high-definition audio and video transmission. With its ultra-compact body design and stable lossless transmission performance, it solves the interference and picture quality loss problems of traditional copper cable transmission, making it a cost-effective choice for commercial and civilian high-definition audio and video transmission.

Product Positioning

This product is a miniaturized 4K/60Hz HDMI 2.0 single-core multi mode Fiber Extender launched by E-link. It consists of the transmitting end (TX) and the receiving end (RX), and must be used in pairs. The overall size is only 57x16x14mm and weighs 0.1kg.

It can be directly plugged into devices for use. The product complies with the RoHS compliant lead-free standards of both Europe and China. The core function is to achieve long-distance transmission of uncompressed and lossless HDMI 2.0 signals through OM4 multi mode optical fibers, and it is an integrated HDMI optical module device.

Importance and Key Features

The core value lies in breaking through the limitations of copper cable transmission, achieving high-definition transmission without RFI/EMI electromagnetic interference and without image quality loss, and ensuring 4K high-definition quality even at a distance of 300 meters.

Key features are prominent: supports 4K@60Hz 4:4:4 full color gamut, 18Gbps high-speed transmission; adopts WDM technology, a single-core OM4 multi mode optical fiber can transmit high-definition audio and video; transmits EDID, HDCP, CEC protocols, compatible with mainstream audio formats such as Dolby and DTS; wide temperature range operation (-20℃ to 70℃), plug-and-play without debugging, supports hot swapping, suitable for complex usage environments.

Working Principle

The product uses an 850nm wavelength as the transmission carrier. The transmitting end converts the HDMI signal into a 18Gbps serial data stream and transmits it through the LC optical port in a single-core OM4 multi mode optical fiber.

The design of TMDS signal fiber transmission significantly enhances the anti-interference capability. At the receiving end, the serial data stream is restored to the HDMI signal. The entire process is without copper conductors, fundamentally avoiding signal loss and electromagnetic interference, ensuring the stability of audio and video transmission.

Installation Tips

This device does not require complex setup. The TX end can draw power from the HDMI interface of the source end. If the device’s power supply is insufficient, an external 5V power supply can be used. The RX end needs to be connected to an external 5V power supply via a Micro USB connector.

Just connect the LC optical ports at both ends with a single-core OM4 multi mode optical fiber to complete the deployment. It supports hot swapping and no additional debugging is required; it can be plugged in and used immediately.

Application Scenarios

Thanks to its high-definition transmission and portability features, the product is widely applicable to three core scenarios: large-screen display for large venues, professional conference systems, and home entertainment. It can meet the long-distance audio and video transmission requirements for large-screen displays in shopping malls, high-definition video conferences in enterprises, and 4K audio-visual equipment in households.

The E-link LNK-109M mini 4K HDMI Fiber Extender features a compact design, 300-meter lossless high-definition transmission, strong anti-interference capability, and easy installation. It strikes a balance between the stability of commercial scenarios and the ease of use in civilian scenarios, making it an excellent solution for cross-scenario high-definition audio and video transmission. It also provides efficient technical support for audio and video transmission in fields such as large-screen displays and conference systems.
