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
For safety, a fiber optic technician or installer should always wear ______ when 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)

The outside diameter of this part of the fiber is the same for most singlemode and multimode
fibers - ✔✔Cladding
Singlemode - ✔✔
Multi-mode graded index - ✔✔
