DTS BE105 THE GOSPELS FINAL
EXAMINATION CERTIFICATION TEST 2026
COMPREHENSIVE QUESTIONS WITH
DETAILED CORRECT ANSWERS VERIFIED
GRADED A+
⩥ What is the main benefit of deploying WDM technology? Answer: It
will increase the capacity of the existing fiber networks tenfold without
adding any more fiber.
⩥ How are optical splitters used in the forward path? Answer: As
passive branching devices that divide an optical signal across multiple
output fibers.
⩥ What is the purpose of a fiber demarcation box? Answer: It provides a
safe place to splice, split, distribute, store, and cross-connect fiber optics.
⩥ What is the purpose of the MST? Answer: It provides access to
connect fiber-optic cable drops from the customer premises to the
network.
⩥ What is the one main function of the FDH? Answer: The FDH
provides effective fiber management by grouping
,splitters into local serving areas
⩥ Which PON element uses patch panels? Answer: ODN
⩥ Which type of fiber topology used in a PON places the PON
splitters at the headend while providing one designated fiber
for every customer premise? Answer: Home-Run
⩥ What are the three categories of the fiber-optic cable used to identify
the location of the fiber in the network? Answer: Trunk, branch, and
drop.
⩥ What is the difference between the FTTN and FTTC
topologies? Answer: An FTC is allowed a smaller number of RF
amplifiers between
the optical fiber and the customer premises.
⩥ What is the purpose of the SDU? Answer: It provides surge
protection, a test jack, circuit protection, wiring management, and fiber
termination.
⩥ What are the advantages of loose buffer tube fiber? Answer: It offers
the best protection for the fibers under high pulling tension and moisture
with its fiber-coated gel.
,⩥ What is an ONU/ONT? Answer: It is a device that converts light from
fiber to RF for coaxial
distribution into the home.
⩥ What are the characteristics of ITU-T G.657 BIF? Answer: It is
flexible for installation in small spaces and has a small bend
radius of 7.5 mm or 10 mm.
⩥ What le true about using a premade fiber-optic pigtail for
splicing to patch panels or terminal equipment? Answer: It is faster and
more rellable than installing eonnectors in the
field.
⩥ What is the proper way to handle fiber once it is spliced? Answer: At
the heat-shrink protective sleeve that has a steel bar inside it.
⩥ What is the purpose of the ground block? Answer: To protect fragile
electronics like TV's and STBs from damaging lightning strikes and
power surges.
⩥ In a PON FTTx network, which OSP device contains fiber test
points that will minimize service disruption to customers? Answer: FDH
(Fiber Distribution Hub)
, ⩥ What parameter is critical in an OTDR when testing a PON with
significant splitters losses? Answer: High Dynamic Range
⩥ What is the best approach to repairing an aerial fiber-optic
drop cable for FTTx applications? Answer: Replace the entire section of
fiber drop cable.
⩥ (-25) + (42) + (-62) + (20) =? Answer: -25
⩥ (17) x (-19) =? Answer: -323
⩥ -17-(-34)=？ Answer: 17
⩥ -49 ÷ -7? Answer: 7
⩥ (20) ÷ (-4) + (-2) x (-10) - (-2) x (7) =? Answer: 29
⩥ 3 6/9 + 6 1/3 + 9 5/9= Answer: 19 5/9
⩥ 7 3/8 ÷7 1/4= Answer: 1. 1/58
