IT IS ALL ABOUT
COMPLING WITH
PROCESS
..it has start and end

WHAT HAPPENS
IN -BETWEEN
IS THE
MANAGEMENT

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
![Page 5: 10 stages of fiber project implemetation](https://reader034.vdocuments.us/reader034/viewer/2022052318/587534a71a28abe7728b5e79/html5/thumbnails/5.jpg)
It begins with
SURVEY of the
PROPOSED ROUTE

STAGE III
TRENCHING
![Page 8: 10 stages of fiber project implemetation](https://reader034.vdocuments.us/reader034/viewer/2022052318/587534a71a28abe7728b5e79/html5/thumbnails/8.jpg)
YOU CAN CALL IT
DIGGING, REMOVAL OF
THE TERRAIN SUFARCE
TO A GIVEN DEPTH
![Page 9: 10 stages of fiber project implemetation](https://reader034.vdocuments.us/reader034/viewer/2022052318/587534a71a28abe7728b5e79/html5/thumbnails/9.jpg)
ASPHALT CUTTING, CONCRETE
BREAKING, THRUST BORING, PAVE
STONES, SWAMP AREAS, BRIGDE
CROSSING are some of the terrain to
work with during
TRENCHING
![Page 10: 10 stages of fiber project implemetation](https://reader034.vdocuments.us/reader034/viewer/2022052318/587534a71a28abe7728b5e79/html5/thumbnails/10.jpg)
STAGE IV : CONCRETE WORKcasting 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 & COUPLINGLaying of
(PVC Polyvinyl chloride) (HDPE: High density polyethene) & GI Pipe
![Page 12: 10 stages of fiber project implemetation](https://reader034.vdocuments.us/reader034/viewer/2022052318/587534a71a28abe7728b5e79/html5/thumbnails/12.jpg)
WHAT IS COUPLINGJOINING OF DUCTS TOGETHER FOR CONTINUITY
![Page 13: 10 stages of fiber project implemetation](https://reader034.vdocuments.us/reader034/viewer/2022052318/587534a71a28abe7728b5e79/html5/thumbnails/13.jpg)
PVC COUPLINGPVC (Polyvinyl chloride)COUPLING INVOLVE SETTING
THE FEMALE SIDE OF THE PIPE AGAINST THE MALE SIDE
![Page 14: 10 stages of fiber project implemetation](https://reader034.vdocuments.us/reader034/viewer/2022052318/587534a71a28abe7728b5e79/html5/thumbnails/14.jpg)
SUB-DUCT COUPLINGTHE 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
![Page 15: 10 stages of fiber project implemetation](https://reader034.vdocuments.us/reader034/viewer/2022052318/587534a71a28abe7728b5e79/html5/thumbnails/15.jpg)
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
![Page 16: 10 stages of fiber project implemetation](https://reader034.vdocuments.us/reader034/viewer/2022052318/587534a71a28abe7728b5e79/html5/thumbnails/16.jpg)
STAGE VII
FIBER WORK
FIBER PULLING : HAND PULLING OR BLOWING
![Page 17: 10 stages of fiber project implemetation](https://reader034.vdocuments.us/reader034/viewer/2022052318/587534a71a28abe7728b5e79/html5/thumbnails/17.jpg)
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
