Why are multimode optical fibers still used today
The equipment used for communications over multi-mode optical fiber is less expensive than that for. An increasing number of users are taking the benefits of fiber closer to the user by running fiber to the desktop or to the zone. Many engineers assume multimode fiber should have disappeared from modern data centers once high-speed single-mode optics became widely available. Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be.
