10 stages of fiber project implemetation

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

It begins with

SURVEY of the

PROPOSED ROUTE

STAGE II

STAGE III

TRENCHING

YOU CAN CALL IT

DIGGING, REMOVAL OF

THE TERRAIN SUFARCE

TO A GIVEN DEPTH

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 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

WHAT IS COUPLINGJOINING OF DUCTS TOGETHER FOR CONTINUITY

PVC COUPLINGPVC (Polyvinyl chloride)COUPLING INVOLVE SETTING

THE FEMALE SIDE OF THE PIPE AGAINST THE MALE SIDE

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

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

STAGE VII

FIBER WORK

FIBER PULLING : HAND PULLING OR BLOWING

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

STAGE VIII

TERMINATION

Connectorization and splicing

STAGE IX : TESTING
