Fibre Cable Installation — Capitalized
Capitalizing the cost of laying fibre optic cable for a new urban coverage area.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Network Infrastructure — Fibre Cable (PPE) | Asset (+) | 2,500,000.00 | - |
| Cash / Contractor Payable | Asset/Liability (-) | - | 2,500,000.00 |
💡 Accountant's Note
Fibre cable has a useful life of 20-30 years and is capitalized as PPE. The high upfront cost and long life make fibre a strategic infrastructure investment — the depreciation charge is low relative to the revenue potential.
Practitioner & Systems Framework
💻 ERP Architecture
Fibre cable installation is tracked as a capital project (WBS element in SAP PS or Oracle Projects) during the construction phase, accumulating in CWIP. The project captures all directly attributable costs: cable material, civil works (trenching, ducting), splicing, testing, and project management. On network acceptance and commissioning, the CWIP is transferred to the fibre cable PPE asset class in the fixed asset module. Fibre is depreciated over 20–30 years using the straight-line method. The fibre route is documented in the network GIS (Geographic Information System), which links to the asset register by route ID.
⚠️ Audit Flags
Auditors confirm that only directly attributable costs are capitalised — allocated overheads and general administrative costs must be excluded. Test that civil work costs (trenching, reinstatement) are capitalised as part of the fibre asset, not expensed as maintenance. Verify that depreciation commences only after the fibre is commissioned and in service. For fibre shared with other operators (dark fibre sold to third parties), assess whether the portion sold should be derecognised or whether an IRU arrangement applies. Test the useful life assumption against the physical lifespan of the fibre.
📄 Required Documentation
Capital project WBS, contractor invoices, commissioning acceptance certificate, CWIP-to-PPE transfer journal, fibre route GIS documentation, asset register entry with useful life, depreciation schedule, and dark fibre sharing agreements (if applicable).
