Traditionally, single-mode has been limited to applications such as long haul, service provider networks, metropolitan area networks, and backbone distribution for large campuses. However, single-mode is now finding its way into shorter reach applications.
In early 2018, Leviton surveyed network professionals about the type of fiber they would install today to plan for future growth, and found a significant jump in OS2 compared to surveys from previous years. This paper will address some prevailing preconceived notions about single-mode fiber — whether true or false — and provide guidance for single-mode testing, cleaning, and inspecting.
