2. Cable Specification
2.1 Introduction
This flat drop cable, which consists of 1, 2, or 4 color coded optical fibers, offers an ideal solution for the smaller fiber counts that are needed in the final sections of an optical network. Two parallel steel strength members protect the optical fibers. The cable is completed with a LSOH jacket
