Type Designation for Core
Code for number of fiber core is indicated by number of the same fiber core. When optical cable is composed of different of fiber cores, "+" sign will be used to separate different fiber cores. Code for fiber core type will be indicated by fiber core type, namely "A" and "B" represent multi-mode and single mode fiber respectively. Fiber cable size is comprised of fiber core sizes.
