@dan_nanni: Fiber optic cables evolved to support growing bandwidth and distance demands. Single-mode fiber uses a narrow core to transmit a single light path for long-distance, high-capacity links, while multimode fiber uses a wider core to carry multiple light paths over shorter, more economical distances. Here is a quick comparison between single-mode and multi-mode fibers 😎👆 Find high-res pdf ebooks with all my networking related infographics at https://study-notes.org #datacenters #ethernet #networkcable #networkengineer #technology
