3G SDI Fiber Converter
Our M‑SD100 3G/HD‑SDI Fiber Extender is broadcast‑grade SDI over fiber optic transmission kit. It supports 3G‑SDI, HD‑SDI, SD‑SDI signal up to 1080P@60Hz resolution, delivers lossless video together with 8‑channel embedded audio via single‑mode single fiber. Transmission distance ranges from 3KM by default up to 20KM.

This SDI fiber transceiver supports local loop output on transmitter and dual synchronous output on receiver. It auto‑detects PAL / NTSC video formats, supports plug‑and‑play and hot‑swap function. Built‑in automatic image adjustment system and ESD electrostatic protection ensure stable signal performance. Compact metal housing size 82*57*27mm, DC5‑12V power supply.

Perfect solution for TV broadcast studio, outdoor live events, stage performance, video conference and AV system integration. Supplied as one transmitter plus one receiver in a full set

M‑SD100 3G/HD‑SDI Fiber Extender

Introduction

M‑SD100 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.

Features

  • Long distance transmission of 3G/HD‑SDI video and audio signals through optical fiber, up to 3‑20KM (default 3KM)

  • HD video signal resolution up to 1920*1080P@60Hz

  • Support all digital lossless transmission, 8‑channel embedded audio and video synchronous transmission

  • Support local output, the remote end support two‑way synchronous output

  • Support PAL/NTSC, strong compatibility, able to automatically identify and configure various display modes

  • Support plug and play and hot plug

  • Built‑in automatic adjustment system, make the image smooth, clear and stable

  • Built‑in ESD protection system

  • 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
