BICSI OSP-001 PRACTISE TEST EXAM QUESTIONS WITH
COMPLETE VERIFIED ANSWERS UPDATED
in areas where future excavation is anticipated, it may be advisable to place the
cable at a greater depth. For example, if road grading that will remove 610 mm (24
in) of dirt is planned in a particular area, it would be wiser to initially place the
cable at 1.2 m (4 ft) versus the standard
610 mm (24 in).
True
placing all of the conduits during the initial conduit system installation is
desirable,
if not mandatory.
*True
*False
True
It is not always necessary to build new pathways for cable placement
*True
*False
True
The length of a cable loop from the switch to a customer depends on three
factors
• Resistance of the cable in ohms
• Signaling limits of the telephone and the terminating device switch in ohms
• Pair loading
Outside Plant (OSP)
Telecommunications OSP cabling began with the placement of the first telegraph
system,
Cable Types
• Optical fiber:
- 62.5/125 micrometer (μm) multimode optical fiber (OM1).
,- 50/125 μm multimode optical fiber (OM2, OM3, and OM4).
- Singlemode optical fiber (OS1 and OS2).
• 100-ohm balanced twisted-pair.
• 75-ohm coaxial.

Methodology
Support structures:
- MHs).
- (HHs).
- Poles, support strands, and guying information.
The basic types of OSP pathways and spaces are:
• Underground.
• Direct-buried.
• Aerial.
advantage to use optical fiber in backbones campus applications:
• Increased distance.
• Higher bandwidth applications.
• All-dielectric cable.
• Less susceptibility to EMI and lightning.
• No crosstalk.
• No grounding (earthing) requirement for all-dielectric cable.
Optical Fiber Connectors:
• LC
• SC
• ST
