OSP Route Planning & Infrastructure Deployment 3

Question 1

In OSP route design, what does the term 'make-ready' refer to?

Accepted Answer

Modifications to existing poles or conduit infrastructure to accommodate new attachments

Answer

Make-ready is the process of upgrading or rearranging existing attachments and hardware so a new cable can be placed in compliance with safety codes.

Question 2

A designer is routing fiber through an area with a high water table. Which underground installation method best mitigates water infiltration into cable pathways?

Accepted Answer

Pressurized conduit systems with end seals

Answer

Pressurized conduit systems maintain positive air pressure to prevent water and contaminants from entering splice points and cable ends.

Question 3

Which ANSI/TIA standard provides guidelines for OSP structured cabling pathways and spaces?

Accepted Answer

TIA-569-D

Answer

TIA-569-D covers pathways and spaces for telecommunications, defining conduit sizing, bend radius, and access requirements for OSP and building entry.

Question 4

A route design requires a fiber cable to enter a building from underground. What structure is used at the building entry point?

Accepted Answer

Building entrance terminal (BET) or entrance conduit with innerduct

Answer

The building entrance terminal or conduit sleeve provides a weatherproof, fire-rated penetration from the OSP environment into the building.

Question 5

What is the maximum allowable unsupported span for aerial self-supporting (ADSS) fiber cable in a standard residential deployment without additional mid-span support?

Accepted Answer

Span limits depend on cable design and local loading zone, typically specified by the manufacturer

Answer

ADSS span capability varies by cable design, sag requirements, and NESC loading zone; manufacturers publish span tables that must be consulted.
