OSP FIBER PROJECT IMPLEMENTATION

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 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 VDUCTING & COUPLING

Laying 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 VIBACKFILLING

& 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 FIBER CABLE TERMINATION

Connectorization and splicing

STAGE IX : TESTING
