terminated inside a patch panel with adhesive/polish or prepolished splice connectors? -
✔✔tight buffer distribution cable

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

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. - ✔✔both fiber type and
wavelenght
✔✔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. - ✔✔Transmitter and receiver power

working with optical fiber. - ✔✔Eye protection
✔✔During fiber optic installations, the most common danger is caused by ______. -
✔✔Fiber scraps or shards from stripping, cleaving, splicing and termination
✔✔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)
✔✔A link loss budget should be done for every cable plant installation during the
______ phase of a project. - ✔✔Design
✔✔The loss of connector on each end of the cable plant ______. - ✔✔Are always
included in the loss budget
✔✔Cladding - ✔✔Material around the center tube (Look at diagram)
✔✔Core - ✔✔Center tube (Look at diagram)
✔✔Primary Buffer Coating - ✔✔Material around the core and cladding, it gives the fiber
its distinct color (Blue, Red, Agua, etc)
✔✔Traps light in the core to reduce attenuation - ✔✔Cladding
✔✔Is smaller in singlemode than multimode fiber - ✔✔Core
✔✔Is stripped off for termination or splicing - ✔✔Primary Buffer Coating
