OPGW · installation
OPGW stringing and installation on transmission lines
We assess OPGW installation scope: engineering review, reel plans, drum logistics, stringing, hardware, downleads, splicing, testing and documentation. The offer defines which tasks can be undertaken and the required resources and qualifications.
Scope, resources, qualifications and schedule are confirmed following technical review of the project.
Scope inputs
OPGW is engineered as part of the line, not as an isolated data cable.
The solution must simultaneously satisfy electrical performance, mechanical behaviour, optical continuity and construction sequencing. Pricing and scheduling therefore follow a review of line parameters, manufacturing lengths, splice locations and the actual logistics of every drum.
Execution engineering
Review of route, structures, spans, angles, environment, short-circuit duty and acceptance criteria before mobilisation.
- Span table and ruling span
- I²t and shield-wire duty
- Sag, tension and reserves
Stringing and installation
Controlled tension stringing, crossing protection, suspension/dead-end hardware, dampers, downleads and reserves.
- Pulling plan by section
- Stringing equipment and communications
- Cable and structure protection
Splicing and testing
Closures, fusion splicing, tray organisation, fibre matrix and bidirectional testing per fibre.
- Closures and downleads
- OTDR at 1310 / 1550 nm
- Dossier by section and fibre

Scope inputs
Information required for a defensible quotation
These inputs turn assumptions into controlled decisions.
- Route length and structure locations
- Span table, angles and support types
- OPGW specification and fibre count
- Short-circuit current/duration or required I²t
- Wind, ice/snow, temperature and altitude
- Maximum manufacturing length and drum dimensions
- Splice points, downleads, reserves and fibre destinations
- Crossings, outages, permits, work windows and access
- Responsibility for cable, hardware, cranes, stringing plant and logistics
- Optical, mechanical, electrical and documentary acceptance criteria
Commercial engineering
Main cost and schedule drivers
Drum count and location
More drums change transport, nodes, closures, splices, reserves and the construction sequence.
Critical spans and crossings
Roads, energised lines, watercourses and steep terrain require specific methods and coordination.
Fibre configuration
Fibre count affects preparation, splicing, tray management, testing and documentation.
High-altitude logistics
Access, weather, autonomy, rotation, rescue and work windows must be built into the offer.
Next step
Deliverables to agree for acceptance
The scope must define which records, measurements and documents apply to the contracted package.
- Reel plan and section sequence
- Splice schedule and fibre allocation matrix
- BOM for hardware, closures, downleads and consumables
- Stringing and operational control records
- OTDR traces and event tables per fibre
- As-built drawings, redlines and final dossier

FAQ
Questions that change scope, price or acceptance.
Can you quote installation only when the client supplies the cable?
Yes. Engineering, installation, splicing, testing and close-out can be separated. Responsibility for cable, hardware, transport, drums, cranes, stringing plant, outages and permits must be explicit.
How is the number of splices determined?
It is derived from actual manufacturing lengths, drum access, downlead nodes, reserves, stringing constraints and the communications architecture—not from a standard number.
What is included in optical acceptance?
Fibre matrix, splice records, bidirectional OTDR traces, event/loss tables, closure identification and as-built documentation to the agreed criteria.
Can you work as main contractor or specialist subcontractor?
Specialist packages or subcontracts for EPCs and main contractors are assessed. Scope, resources, responsibilities and deliverables are agreed before quotation.
