Broadly, the most common application for Multi-Mode fiber cable is to create a backbone for a company's network. If you're looking at 802.11ac or newer WiFi access points, a Multi-Mode fiber backbone is virtually required to get top speeds out of your access points.

Do I need single mode or multimode fiber?

Single mode fiber has a smaller core than multimode and is suitable for long haul installations. Single mode systems are generally more expensive. Multimode fiber has a larger core and is recommended for fiber runs less than 400 m (1300 feet). ... Multimode systems are generally less expensive.

Why do we need multimode fiber?

Multimode fiber optic cable has a large diametral core that allows multiple modes of light to propagate. Because of this, the number of light reflections created as the light passes through the core increases, creating the ability for more data to pass through at a given time.
