fiber optic project implemetation procedure
TRANSCRIPT
STAGE I
PROPOSED ROUTE SURVEY
After studying the SOW from the client .
It is important to survey the project route and take
note of the terrain.
The use of GPS and knowledge of it with other
mapping
software is an hedge in this stage
STAGE II
DRAFTING AND DRAWING OF
THE SURVEY

ASPHALT CUTTING, CONCRETE
BREAKING, THRUST BORING, PAVE
STONES, SWAMP AREAS, BRIGDE
CROSSING are some of the terrain to
work with during
TRENCHING
STAGE IV : CONCRETE WORK casting of MANHOLE and ROUTE MARKER
Manhole are the concrete junction box site at given interval on the project route
THIS CAN BE CONSTRUCTED ON SITE (IN-SITU)
OR
CAST IN THE PROJECT EQUIPMENT LOCATED (PRE-CAST)
Route marker are the short pillars erected along the fiber route to indicate the
presence of underground telecom facilities
STAGE V
DUCTING & COUPLING Laying of
(PVC Polyvinyl chloride) (HDPE: High density polyethene) & GI Pipe
PVC COUPLING PVC (Polyvinyl chloride)COUPLING INVOLVE SETTING
THE FEMALE SIDE OF THE PIPE AGAINST THE MALE SIDE
SUB-DUCT COUPLING THE SUB-DUCT KNOWN AS HDPE (High Density
Polyethylene) VARY IN SIZES 33/40mm. It is uniform
in size. Unlike PVC, it does not have male and female
sides. joining requires a special coupler
and techniques
STAGE VI
BACKFILLING
&
REINSTATEMENT
This term refers to the returns of the excavated soil to the trench. Warning tape is
required here before total backfilling. Reinstatement only takes place where
major terrain such as asphalt cutting and concrete breaking take place
It involve inserting of the fiber
optics cable into the sub-duct
from manhole to manhole to the
end of the cable drum or
cassette.
Equipment such as the calibration rope, stager,
hand and blowing machine can be deployed
to achieve this stage
