The E-link LNK-D4K-SM series represents a breakthrough in long-distance 4K signal transmission

technology, specifically engineered for extreme-distance applications requiring uncompromised video

quality. This professional-grade fiber transceiver utilizes single-mode fiber optic technology to deliver

pristine 3840×2160 resolution video over distances ranging from 10km to 80km, with 1.4km as the

default configuration. The advanced fiber optic architecture completely eliminates electromagnetic

interference and signal degradation, ensuring perfect image quality even at maximum transmission

distances.

Featuring manual EDID management capability, this versatile transceiver provides technicians with

complete control over display configuration settings, making it ideal for custom installations and

specialized applications. The compact, rugged design incorporates industrial-grade components

capable of withstanding challenging environmental conditions while maintaining stable performance.

Supporting full HDMI 1.4 standards and 4K resolution at 30Hz, this reliable solution is particularly

suited for long-distance applications in transportation systems, security surveillance networks, and

campus-wide AV distribution where conventional copper-based systems prove inadequate.

The transceiver's enhanced optical power budget and sophisticated signal processing technology

guarantee consistent performance across the entire transmission range, while the flexible configuration

options allow optimization for specific installation requirements. With its exceptional distance capabilities

and robust construction, this mini fiber transceiver establishes new standards for remote video transmission

in broadcast facilities, industrial monitoring systems, and large-scale digital signage deployments where

both signal quality and transmission distance are critical operational parameters.
