RS232/422/485 Fiber Extender

Project Description

20KM Industrial RS232/422/485 Fiber Extender

Model Number:HD-R20A

Our series all-digital video converter adopts international advanced SOC digital signal processing technology and all-digital video uncompressed transmission technology, which uses multi-channel video, data, and signals to adopt CWDM wavelength division multiplexing technology provides real-time synchronization, distortion-free, high-quality transmission on single-core fiber, and adopts all-digital communication mode. It can select real-time synchronous, distortion-free, high quality transmission of 1 to 32-channel video on a single-core fiber.The optimized design of the video converter ensures high reliability operation in a variety of harsh environments. The plug-and-play design makes installation easier and does not require any light or electrical adjustment. Various status indicators provide fast DDM. The fiber module and core circuit of the all-digital video converter adopt imported components, which have high stability, all finer and Ethernet interfaces are in line with international standards, free from adjustment during installation, suitable for different working environments. Supports desktop and 1U rack style.

Uncompressed Digital Video Converter are widely used in urban traffic monitoring systems, public security organs, safe city monitoring systems, highway security, toll systems, buildings, campus monitoring networks, industrial monitoring (airports, chemicals, steel, oil, railways, water conservancy , mines, etc.), military surveillance (warehouse, border defense, guard, defense, etc.) power oil field, television station program transmission system stadium (live video, audio transmission).

Features:

1.Support RS-232/RS-485/RS-422 ports;

2.Support synchronization, point-to-point, point-to-multiple transmission;
