Outside Plant (OSP) Fiber Optic Scope of Work

1. Survey & Design

• Route survey and site walkouts.

• Identification of obstacles (roads, railways, utilities, bridges).

• Preparation of detailed design drawings and shop drawings.

• Route approvals and Right-of-Way (ROW) coordination with authorities.

2. Civil Works

• Trenching & Excavation

  • Standard trenches with sand bedding and backfilling.

  • HDD (Horizontal Directional Drilling) under roads, rivers, and hard surfaces.

• Duct Bank Installation

  • HDPE ducts, sub-ducts, and micro-ducts.

  • Sealing, mandrel testing, and pulling rope installation.

• Manholes & Handholes

  • Construction and installation of fiber chambers.

  • Placement of joint boxes, splice enclosures, and marker posts.

3. Cable Installation

• Laying of fiber optic backbone cables (singlemode OS2).

• Blowing, pulling, or jetting of cables into ducts.

• Armored or dielectric cable installation depending on soil conditions.

• Aerial installation (if applicable): pole-mounted fiber, ADSS cables.

4. Splicing & Termination

• Fiber splicing in manholes/handholes.

• Termination at Optical Distribution Frames (ODF) at datacenter/POP entry.

• Splice closures, protection sleeves, and proper slack storage.

• Labeling of all splices and termination points.

5. Testing & Acceptance

• OTDR Testing at 1310/1550 nm.

• Power Meter & Light Source Testing for insertion loss.

• Continuity Checks (visual fault locator).

• End-to-end test reports for each fiber core.

6. Documentation & Handover

• As-built drawings with route maps and manhole locations.

• Fiber allocation sheets (core assignment).

• OTDR traces, loss test reports, and continuity results.

• Route markers and labeling of manholes/handholes.

• O&M manual and maintenance guidelines.
