Structured Cabling ના મુખ્ય ભાગો

1. Entrance Facility (EF)
   ISP અથવા telecom service provider નું connection building માં જ્યાં આવે છે.

2. Equipment Room (ER)
   જ્યાં servers, network switches, firewalls, storage systems વગેરે install થાય છે.

3. Telecommunications Room (TR) / IDF
   દરેક floor માટે network distribution room.

4. Backbone Cabling
   MDF થી IDF અથવા building થી building connection.
   સામાન્ય રીતે fiber optic cable use થાય છે.

5. Horizontal Cabling
   IDF થી user location (computer, IP phone, CCTV) સુધી cabling.
   સામાન્ય રીતે CAT6 / CAT6A UTP cable.

6. Work Area Components
   User side devices:

   • Faceplate

   • I/O module

   • Patch cord

   • Computer / IP phone / camera

Structured Cabling માં ઉપયોગ થતું Material
