In the Fiber transmission application, there is single mode and multi-mode ,what’s the difference ?
Single mode: Light travels along a path, used for long distance transmission up to 5KM
Multi mode: Light travels along multiple paths,used for short distance.
Below is the color difference
Below is the fiber inner diameter
Differences in light sources
Light sources usually include laser light sources and LED light sources. Single-mode optical fiber uses laser light sources, while multi-mode optical fiber uses LED light sources.
The choice between single-mode fiber and multi-mode fiber should be based on the actual transmission distance and cost.
If the transmission distance is 300-400 meters, multi-mode fiber can be used. If the transmission distance reaches several thousand meters, single-mode fiber is the best choice.
We have HDMI Fiber extender support single mode fiber and multi mode fiber, our HDMI Fiber extender delivery with single mode fiber inside, so please connect the extender with single mode fiber cable. If you want to use multi mode fiber cable, you can change the single mode fiber to multi mode fiber, you can take our the fiber module from the extender and replace with multi mode fiber and connect with multi mode cable for signal transmission. Quality is very stable.
