EXAMS |UPDATED QUESTIONS AND CORRECT
ANSWERS |
1.In what applications is a splice closure used? - ANSWER-Splice Closures are used
to protect optical fibers and splices against a full range of environmental changes
in aerial installations or below ground in vaults.
2.When preparing a fiber-optic cable for splicing, what is the purpose of removing
approximately 2.5 cm (1 inch) of jacket and any armor that is present, from the
end of the cable?When preparing a fiber-optic cable for splicing, what is the
purpose of removing approximately 2.5 cm (1 inch) of jacket and any armor that is
present, from the end of the cable? - ANSWER-To access the cables rip cord and
to check the cutting depth of the knife or ringing tool.
3.Which element of a passive optical network (PON) consists of a downstream
(forward path) optical transmitter, an upstream (return path) receiver, and a
multiplexer/demultiplexer? - ANSWER-Optical line terminal (OLT)

4.What is it about radio frequency over glass (RFoG) that made broadband cable
operators envision using it to make a seamless transition from the legacy hybrid
fiber/coax (HFC) architecture over to a gigabit-capable passive optical network
(GPON) or Ethernet passive optical network (EPON)? - ANSWER-RFoG can operate
in parallel with GPON and EPON, operating independent of the PON
communications protocols and data rates.
5.What is the core objective of the Data Over Cable Service interface specification
(Docsis) Provisioning of Ethernet passive optical network (EPON), or DPoE, access
architecture? - ANSWER-To make the EPON elements appear and operate as
DOCSIS elements to the existing DOCSIS-based back office provisioning
operations.
6.How should the buffer tubes be secured in the closure? - ANSWER-The buffer
tubes should be secured with tie wraps to allow slight movement without pulling
or stressing the optical fibers.
7.How are optical splices secured in a splice tray? - ANSWER-Retaining clips hold
optical splices in place in a splice tray.

8.What is the Purpose of Buffer tubes in a fiber optic cable? - ANSWER-Buffer
tubes protect and separate the optical fiber in smaller bundles
9.When splicing fiber-optic cable, why is it a good safety practice to clean off fiber
strippers and other hand tools after each use? - ANSWER-To prevent the
accidental transfer of fiber debris or fiber chips onto clean hands.
10.Where would you expect to install a mid-entry splice in a fiber-optic cable
network? - ANSWER-A location where a select number of optical fibers need to be
spliced, and the remaining buffer tubes and fibers remain untouched.
11.Which type of fusion splicer is ideal for fiber-to-the-x (FTTx) splicing? -
ANSWER-The fixed V-Groove splicer.
12.When would a mid-entry splice in a fiber-optic network be used? - ANSWER-In
a self-healing ring network that requires only two fibers to feed an optical fiber
drop.
