Fiber Optic Requirements

If estimated fiber losses are suspected of exceeding loss limits due to excessive length, splices, and so forth, perform OTDR (Optical Time Domain Reflectometer) or Optical Power Meter tests to ensure a successful installation of a remote EPN fiber link.

The requirements that determine the maximum fiber optic cabling distances are:

■The mean loss and the length of the outside plant fiber cable

■The mean loss and the length of fiber cable shipped with the cabinet (including any fiber riser cable)

■The mean loss of an ST connector and the number of ST connections

■The mean loss due to the total number of splices

■Higher-order mode loss
