: XX cores single-mode optical fiber (ITU-T Rec. G.657A)

XXXXm

: Mark of meters

*The marking is printed every 1 meter;

● The color of marking is white, but if the remarking is necessary, the yellow color marking shall be printed newly on a different position.
● An occasional unclear of length marking is permitted if both of the neighboring markings are clear;
● The both cable ends are sealed with heat shrinkable end caps to prevent water ingress.
