Additionally, fiber optic cables are more durable and require less maintenance than copper cables, which can be prone to corrosion and other forms of damage over time. Multimode Fiber (MMF) has a core diameter, typically 50–100 micrometers, has ability to transfer multiple modes of light through the fiber core, uses lower-cost electronics (LED, VCSEL) operates at the 850 nm and 1300 nm wavelength and is used for short distance interconnections (up to 550m). While traditional cables are still widely used, fiber optic cables have several advantages over copper cables. They can transmit data over longer distances with less signal loss, they are less susceptible to interference from electromagnetic fields, and they can transmit data at higher speeds. Single mode fiber has a very narrow core (around 8–10 microns in diameter), so it only allows one light signal (or "mode") to pass through at a time. Although they can do the same job in some instances, the different construction methods make each of them better suited to certain tasks and budgets. That makes picking between single mode and multimode fiber optic cables an. Cables.
