Ⅰ. Introduction
The fiber extender transmits 3G/HD-SDI video signals over a long distance through a single fiber cable, and supports 8-channel embedded audio synchronization function; It can adapt to a variety of complex application environments.
The equipment has excellent image processing and transmission capabilities, making the signal transmission more smooth and stable. It is a reliable, high performance and efficient 3G/HD-SDI signal extension mode.
Ⅱ. Features
1. Long distance transmission of 3G/HD-SDI video and audio signals through optical fiber, up to 3-20KM (default 3KM)
2. HD video signal resolution up to 1920*1080P@60Hz
3. Support all digital lossless transmission, 8-channel embedded audio and video synchronous transmission
4. Support local output, the remote end support two-way synchronous output
5. Support PAL/NTSC, strong compatibility, able to automatically identify and configure various display modes
6. Support plug and play and hot plug
7. Built-in automatic adjustment system, make the image smooth, clear and stable
8. Built-in ESD protection system
9. Simple to install, plug and play
Troubleshooting
1. The red light (PWR) is not bright or the brightness is low, Check whether the power adapter is normal
2. When TX green light (STA) is not on;
Check the signal source;
The green light stays on indicates regular work.
3. RX green light (STA) is not on, check whether the optical fiber module of
the TX contacts normally; The green light (STA) is not on when there is no signal from the TX; Long light indicates that TX and RX work normally.
4. If there is no image on the display, check whether the display selects the correct channel input
