ข่าว บริษัท เกี่ยวกับ Reliable Transmission Over 80km: Eliminate DVI Signal Interference Today
In scenarios where high-definition audio and video as well as control signals need to be transmitted over long distances, issues such as signal attenuation and interference often affect the transmission quality. The E-link LNK-DVI-1D1BA DVI Fiber Optic Extender, as a professional fiber optic extender product, realizes the integrated transmission of DVI video, bidirectional stereo audio, and RS232 control signals through a single fiber. With stable performance and high compatibility, it has become the preferred solution for various long-distance signal transmission scenarios.
The E-link LNK-DVI-1D1BA is a Fiber Optic Extender that integrates DVI video, 1 channel of bidirectional stereo audio, and 1 channel of RS232 signal transmission. It is developed by E-link China Technology. Its core function is to extend various signals through a single fiber, compatible with DVI 1.0 and HDCP 1.2 standards, and can automatically match the signal source and display device. It is an integrated signal transmission device suitable for commercial and industrial scenarios.
The core value of this product lies in solving the distance limitations and interference problems of traditional electrical signal transmission, achieving lossless long-distance transmission of high-definition signals, and meeting the requirements of high-resolution and multi-signal synchronization transmission scenarios.
Its key features are prominent: under single-fiber transmission, single-mode fiber can reach up to 80km, and multi-mode fiber ≤ 500m; supports the highest resolution of 1920×1200@60Hz, and is specially adapted for 1600×1200@60Hz; equipped with a 3.5mm stereo audio interface and 3-pin RS232 terminal block, with RS232 baud rate ≤ 115200; built-in ESD protection and image automatic adjustment system to ensure stable transmission, and DC5V power supply, with the maximum power consumption being only 4W, capable of operating in a wide temperature range of -20°C to +70°C.
In terms of working principle, the product is divided into the transmitting end and the receiving end. The transmitting end collects DVI, audio, and RS232 electrical signals and converts them into optical signals through the SFPLC interface for transmission through a single fiber. The receiving end then restores the optical signals to electrical signals and outputs them synchronously to the corresponding display and control devices. The built-in system can automatically match the signal parameters, ensuring clear and stable images.
Installation follows a simple principle, designed as plug-and-play; the DVI cable length should be controlled within 5 meters to avoid signal attenuation; the fiber interface should be distinguished as single-mode/multi-mode corresponding to 850nm/1310nm/1550nm wavelengths; audio and RS232 should be connected according to the device identification, with DC5V power supply directly connected, without complex configuration.
This optical Extender is suitable for various scenarios that require long-distance synchronous transmission of high-definition signals and control signals. The core includes remote signal expansion of computer display systems, remote control of RS232 controllers in industrial fields, signal transmission of commercial audio and video playback systems, and also can be adapted to scenarios with requirements for signal transmission stability and distance in security monitoring, conference systems, etc.
The E-link LNK-DVI-1D1BA DVI Fiber Optic Extender, with the core advantage of single-fiber multi-signal transmission, combines high resolution, high compatibility, and easy installation, perfectly solving the pain points of long-distance transmission of high-definition audio and video and control signals. Its compact body (120x83x28mm) and stable performance make it highly adaptable in industrial, commercial, and other scenarios, and is a cost-effective choice for long-distance signal transmission.
