💡 Accountant's Note

The thousands of miles of fiber optic cable running through the ceilings (cable trays) are capitalized assets. This 'backbone' is required to provide connectivity services to tenants. Under the matching principle, this cost is depreciated over the estimated useful life of the cabling (typically 15–20 years), even though individual cross-connects (the patch cables) are expensed.

Practitioner & Systems Framework

💻 ERP Architecture

Infrastructure cabling is often recorded as 'Plant' or 'Network Assets.' It is vital to separate 'Permanent Back-plane' fiber from 'Temporary Patch' fiber, as the latter has zero recovery value and should be expensed.

⚠️ Audit Flags

Verification of 'In-Service' date. Fiber is often installed in phases. Auditors check that depreciation begins when the fiber is 'lit' and available for customer traffic.

📄 Required Documentation

Fiber map/schematics, contractor invoice for 'pulling and splicing,' and light-loss test results proving the line is functional.
