Does outdoor fiber optic cable support multimode or single-mode

All three formats can be built with either single mode or multimode fiber (single mode being far more common for several reasons — learn more) and in a variety of strand counts. A fiber optic cable (frequently shortened to “fiber cable”) is a specialized transmission medium crafted to carry data as light pulses through ultra-thin strands of glass or plastic known as optical fibers. Standard indoor/outdoor fiber optic cables are among the most commonly integrated due to their low cost, easy handling. There are two main types of fiber optic cables: single mode and multimode. 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. These two categories define how light travels through the fiber core: Transmits a single light mode; very low attenuation; supports long-distance transmission up to 100 km or more.
