EkoLink II

1.2.2 Fiber
EMS recommends single mode 9/125 µm optical fiber for use in the EkoLink II
system. It is also recommended that a high quality SC/APC connector be used to
minimize reflections at the mating ends of the fiber. SC/APC connectors are
standard on both the Remote and the Hub. All connectors should be thoroughly
cleaned prior to each mating and plastic caps used to cover the connectors when
not mated. Dust and other contaminants can scratch and permanently damage
fiber connectors.
The maximum length for a fiber run is a function of the loss within the fiber itself
plus some margin for aging and other factors.
