Product introduction

1. Overview

HC3711 transmits digitally high-resolution RGB (up to WXGA) and stereo audio over one  fiber single-mode or multimode, 1310nm wavelength, point-to-point, point-to-multipoint and drop-and-repeat applications, it supports VGA, SVGA, XGA and WXGA (640 x 480, 1024*768, and 1280*1024, up to 1366 x 768) or RGBHV format. 

2. Features

«  1-channel VGA video signal of computer over 1-core fiber

«  1-channel stereo audio with transmission of the same direction

«  1-channel RS232 data transmission with the same direction (optional bidirectional transmission)

«  1-channel switch transmission, with the same direction (optional bidirectional transmission)

«  Sampling clock phase adjustment

«  Image brightness adjustment

«  Image contrast adjustment

«  10-bit digital video encoding and uncompressed transmission technology

«  Be used in long-distant transmission of industrial monitoring and large venues, etc.

«  The parameters could be saved, and also could be saved after power is turned-off

«  Plug and play at any time, basically no need to be adjusted and could be up to image output of high-quality

«   Power and indicators of other parameter could monitor system status

«   Automatic identification of input video format, receiver outputs industry-standard video

«   Using power conversion technology, could effectively resist environmental interference of power

«   4U rack mount, 1U rack mount and stand-alone

«   Lower power consumption and free installation, debugging
