What Is BIMMF?
What Is BIMMF?

Designing and deploying fiber optic networks is always a challenge. No matter the plan, you will need unique design elements and customized solutions for some of your problems.

Interestingly enough, one of the most common issues with fiber optics is figuring out how to get the cables to run the path that you want and still perform well. Fiber optic lines are notoriously bad at handling bends and corners.

How do you account for that?

One of your best options is to invest in BIMMF cables.

What Is BIMMF?

The acronym stands for “bend insensitive multimode fiber.” This is a term for specific fiber optic cables that are designed to handle sharper bends during the cable run. If you need to put sharp turns in your cable to make it fit, you might need to use BIMMF cables to get the job done.

Why Does BIMMF Matter?

Why, specifically, would you need BIMMF cables?

Well, fiber optic cables are very precise, sensitive systems that can communicate at high speeds across long distances. While many cable designs aim to make them robust, the actual optical fibers inside of a cable are quite delicate.

With standard fiber optics, very sharp turns can put a kink in the cable, and kinking fiber optics essentially breaks them. While many copper cables can recover from a kink, fiber optics can’t, so sharp turns in the cable can ruin it.

Even when the bend doesn’t kink the cable, a sharp turn can still create signal loss. This is because of how light works. It can only move in straight lines. The fiber optics can help turn a light signal around a corner, but there are limitations. When a curve is steep enough, you will lose some of the light, and that can turn into signal loss and slower effective data rates.

In many cases, you can find ways to take sharp angles out of the run, but when that isn’t the case, you want something that is designed specifically to handle steeper bends. That brings us back to BIMMF.

How Does BIMMF Work?

BIMMF works on a pretty simple principle. It adds space inside of the cable. With that extra space (often called a trench), there’s more room for the interior of the cable to bend without pinching off some of the light transmission.

While the principle is simple, the engineering is a bit more complicated. The trench is added to the interior of the cable without significantly changing the thickness of the cable or other performance parameters. In short, it’s an impressive trick of engineering that yields cables that can handle a lot more versatility in how they are deployed.

Here’s the bottom line. If you use fiber optic cables, there’s a good chance that you need to bend them in order to build your network and/or infrastructure. If you want cables that can handle those bends, then BIMMF is a good solution.

That’s exactly why all premium cables at Cables and Kits are BIMMF. If you’re getting premium cables, then you should be able to rely on them regardless of deployment. That’s the BIMMF advantage that we want you to enjoy.
