**Is LC single mode or multimode?**.

LC connectors can support both single mode and multimode fibers. The LC connectors themselves are the same for both single mode and multimode applications. The key difference between single mode and multimode fibers is the size of the core and the way light is transmitted through them.

### Single Mode.

Single mode fibers have a much smaller core size (typically 9 microns) compared to multimode fibers. This small core size allows for a single mode of light to travel straight down the center of the fiber without reflecting off the edges. This results in less dispersion and allows for higher bandwidth over longer distances.

### Multimode.

Multimode fibers have a larger core size (typically 50 or 62.5 microns) compared to single mode fibers. This larger core size allows for multiple modes of light to travel through the fiber, bouncing off the edges of the core. While multimode fibers have a shorter transmission distance and lower bandwidth compared to single mode fibers, they are more cost-effective for shorter distance applications.

In summary, LC connectors can be used with both single mode and multimode fibers. The choice between single mode and multimode depends on the specific application requirements such as distance, bandwidth, and cost.
