The discipline behind the asset.
Five engineering practices, one shared standard of evidence: if it was not measured, it did not happen.
Practices
Route engineering
Corridor selection, risk modelling, land tenure and crossing design.
Optical engineering
Loss budgets, dispersion, amplification and spectral planning.
Transport architecture
DWDM, packet transport, protection schemes and capacity forecasting.
Facility engineering
Power, cooling, structural and fire systems for critical buildings.
GIS & asset data
Sub-metre as-built records — the only reason a repair takes hours instead of days.
Standards we build to
How infrastructure actually gets built.
Nine phases. Each is a gate — nothing proceeds until the previous phase is signed.
01 / 09 · Survey
- 01GNSS RTK · ±20 mm
Survey
Before anything is designed, the ground is measured. RTK GNSS traverse, buried-utility detection, geotechnical sampling and a route walked on foot — because the map is never the territory.
- 02ITU-T L.100
Design
Route selection trades distance against risk: flood plains, seismic zones, planned road widening, land tenure. The shortest path is almost never the right one.
- 03Right-of-way
Permitting
Right-of-way across ministries, railways, municipalities and private landholders. The slowest phase — and the one that decides whether the project exists at all.
- 04HDD · 1.2 m
Earthworks
Open-cut where it is safe, horizontal directional drilling where it is not. Rivers, highways and railways are crossed without breaking the surface.
- 05HDPE 40/33
Duct
HDPE subduct laid at 1.2 metres with warning tape, marker posts and chambered access every 500 metres. The duct will outlive three generations of cable.
- 06288 F · G.652.D
Cable
Up to 288 fibres blown — never pulled — in two-kilometre sections. Blowing keeps tension off the glass, and tension today is attenuation in ten years.
- 07≤ 0.05 dB
Splicing
Fusion splicing in a climate-controlled trailer, every joint measured bidirectionally. The tolerance is five hundredths of a decibel. Nothing is rounded up.
- 08OTDR · 1550 nm
Certification
OTDR traces at 1310 and 1550 nm, end-to-end loss budget, chromatic and polarisation-mode dispersion. The span is handed over with its own birth certificate.
- 0924 / 7 / 365
Operations
Commissioned into the NOC with its baseline optical signature recorded. From this hour the span is watched continuously, for the rest of its working life.
