Pathway Considerations
In planning for OSP cabling, cable infrastructure must be determined irst. The choices
are underground, direct-buried, and aerial.
Underground plant
most expensive system, has the highest cable placement capacity, longest projected
lifespan, typically in excess of 50 years. Highest initial cost
Direct-buried plant
A lifespan of 30 years or shorter, depending on different conditions
Aerial plant
Aerial plant typically has an expected life of about 30 years
Route approval
OSP designer should discuss routing with the customer. The customer may have
reasons not to use the proposed route (e.g., future plans for buildings and parking lots)
Force route changes
field conditions may force route changes:
• Adverse ground conditions
• Coordination with other utilities
• Missing easement or permits
• Customer space utilization issues
