TDMM.* Page 22-1

Question 11

True or False
The ICT designer may select
items that are suitable for
OSP applications when
designing the cabling system
for a special occupancy
premises.

Answer 11

True. Special occupancy areas
may require cabling that is not
affected by exposure to severe
climatic conditions. As a result,
the ICT designer may select OSP
components to address these
challenges.
