Which type of cable is best suited for indoor installation when fibers ar to be directly
terminated inside a patch panel with adhesive/polish or prepolished splice connectors?
tight buffer distribution cable
What type of cable may require installation of a breakout kit (also called a furcation or fan
out kit) for termination?
loose tube (loose buffer) cable
When pulling cables, the minimum bend radius under tension is generally specified as
______.
20 times the cable diameter
Cable ties used on fiber optic cables ____.
Can harm cables if too tight, so they should be hand-tightened.
Fiber optic joints (connectors or splices) should have ____.
low loss, minimal reflectance and high mechanical strength
To reduce _____ as well as loss, the end of a connector ferrule is polished to a PC (physical
contact) finish.
Reflectance
Factory terminations such as used for making patchcords, generally use what method of
attaching the connector?
Epoxy/polish
According to the references, the connector in the following list with the best or lowest
reflectance would be the ____.
SC-APC (Angled Polished Connector)
Splices are most often used for _____.
A permanent joint between two fibers
If you need to permanently join two fibers together with the lowest loss and least amount of
reflectance, which of the following should you choose?
, fusion splice
Mass fusion splicing is normally used on what style of cable?
ribbon cable
Prior to cable plant acceptance or system turn-up, a(n) _____ is used to measure the cable
plant insertion loss to ensure it is within the loss budget.
Light source and power meter (LSPM or OLTS)
For insertion loss testing, the fiber optic test source must match the _____ of the
transmission system or the standards covering the cable plant.

According to the text, it is recommended that reference test cables be chosen for their
__________>
low loss
Which of the following parameters cannot be measured by OTDRs (optical time domain
reflectometers) in fiber optic networks.

The link loss budget analysis of a cable plant like the diagram shown is done to _________.
All of these choices
(Ensure the intended communications system will work on the cable plant system, Provide a
pass/fail loss value for comparison to test values, Ensure the cable plant has been properly
installed)

of a project
Design
The loss of connector on each end of the cable plant ______
