SDI Fiber Converter with RS485 RS422 RS232 Ethernet CWDM 3.2Gbps

Product Specification

Model: LNK-HD3GSDI

 Product Description & Overview

The SD/HD/3G-SDI + RS485/RS422/RS232 Data + 10/100M Ethernet over Fiber Converter provides

a comprehensive multi-signal transmission solution for demanding professional environments. Utilizing

advanced all-digital optical fiber transmission technology, this device ensures high-integrity transport of

uncompressed SDI video signals, including embedded audio and time code, alongside vital control and

data channels over a single optical fiber. The converter excels in delivering long-distance, distortion-free

video transmission while maintaining broadcast-quality clarity and stability, making it an ideal backbone

for complex, mission-critical video and data networks.

Engineered for operational transparency and ease of use, the converter features intuitive LED status

indicators that allow for immediate visual monitoring of power, fiber link integrity, and signal activity. Its

enhanced flexibility is anchored by integrated support for RS485, RS422, and RS232 serial data protocols,

enabling bidirectional transmission of control commands, sensor data, and switch status information. This,

combined with a standard 10/100M Ethernet port, allows for seamless network integration and remote

management, empowering users to customize the system to meet diverse and evolving application

requirements without compromising performance.

This versatile converter is designed to serve a wide array of industrial and commercial applications.

Key deployments include intelligent transportation systems for traffic monitoring, expansive security

and surveillance networks, and robust industrial monitoring in sectors such as power generation,

chemical processing, and oil and gas. Additionally, it is perfectly suited for broadcasting applications

like TV program transmission and live event production in stadiums, as well as for military perimeter

security and facility monitoring. By consolidating video, data, and control signals onto a single, reliable

fiber link, this converter simplifies infrastructure, reduces costs, and delivers the high reliability required

for 24/7 operations in the most challenging environments.
