Optical fibre cable marking is an indispensable part of optical cable

which is of great significance to the manufacturer’s production

quality control and operator’s construction and line maintenance. In this paper

the advantages and disadvantages of the optical cable marking printing method are briefly analyzed. In view of the defects such as indistinctness

incompleteness

residual border and the deviation of the embossing wheel baseline from the center of the optical cable

which are easy to appear in the hot embossing process. This paper mainly analyzes the reasons from the aspects of optical cable positioning stability

hot embossing material

embossing wheel block and so on

and makes several improvements

so that the effect of optical cable hot embossing has been improved obviously.
