Before you can begin to design a fiber optic cable design, one needs to establish with the user or network owner where the network will be built and what communications signals it will carry. (LANs or Local area network)And security systems use structure cabling systems built around well-defined industry Standards. Many campus carry backbone network used in industrial complexes or Institutions uses as long as 500 m or more cabling requiring optical fiber. Telephone networks are mainly outside the building (OSP) systems, connecting buildings over distances as short as few hundred meters to hundreds or thousands of Kilometers. Data rates for telecom are typically 2.5 to 10 gigabits per second using very high power lasers that operate exclusively over single modes fibers. Designing long distance or outside building application generally means choosing cabling containing singlemode (SM) Fiber over all other media. Many users may opt to use FTTD, as a complete fiber network because its very cost effective solution, negating the requirement for telecom rooms full switches, with data quality power and grounds, plus year-round air conditioning. Also choosing transmission equipment is the next step in designing a fiber optic network. This step will usually be cooperative venture involving the customer, who knows what kind of data they need to communicate, the desiner and installer, and the manufactures of transmission equipment. Also, the hardware must be appropriate for the location, which can be outdoors, hung on poles, buried, inside pedestals. Vaults or buildings, etc. Sometimes the hardware will need to be compatible with local zoning. The higher bandwidth OM3/OM4 standard fiber is considered the best choice. Make sure all cabling meant the recommendation and legal requirements needed. When setting up the
