Size an FTTH Network

Educational objectives :

  • Master the Engineering Rules in ZMD, ZTD-BD & RIP from PA to PB (PRE)
  • Being able to design a fiber optic network (explore possibilities of optical cable routing and equipment / infrastructure set up) on a GIS.
  • Read and interpret any kind of plan.
  • Perform or update the synoptic.
  • Modify the technical plans based on information provided by the field and finalize the study.
