Structured Cabling
SANS 11801 — ISO/IEC 11801 — TIA-568
Structured cabling is the standardised physical infrastructure that carries data, voice, and other signals throughout a building. A properly designed and installed cabling system is the foundation of any reliable network. In South Africa, installations follow SANS 11801 (the local adoption of ISO/IEC 11801) and/or the TIA-568 series, which is widely specified for commercial buildings.
Standards referenced
-
SANS 11801 (ISO/IEC 11801:2017) — Generic cabling for customer premises. Covers performance requirements for copper and fibre cabling, topology, and component specifications.
-
TIA-568.2-D — Balanced twisted-pair telecommunications cabling components, covering Cat5e through Cat8.
-
TIA-568.3-D — Optical fibre cabling components, covering multimode (OM3/OM4/OM5) and single-mode (OS2) fibre.
-
SANS 50174 (EN 50174) — Installation of cabling systems. Covers planning, installation workmanship, and testing requirements.
Copper cable categories
Cat5e (Class D)
Supports Gigabit Ethernet (1 Gbps) at up to 100 m. Minimum recommended for new installations.
Cat6 (Class E)
Improved performance; supports 10 Gbps at distances up to 55 m. Preferred for most commercial installations.
Cat6A (Class EA) — Recommended
Supports 10 Gbps at full 100 m runs with reduced crosstalk. SoftSol’s default specification for new commercial installations.
Fibre optic (OM3 / OM4 / OS2)
Used for high-bandwidth backbone runs, inter-building links, and environments where copper is impractical.
How SoftSol installs
A note on inherited and existing cabling
Where SoftSol takes over management of a site with pre-existing cabling infrastructure, full conformance to the current standard cannot always be guaranteed. Cabling installed by others may not meet the specification, category, or workmanship requirements of SANS 11801 or TIA-568 — particularly in older buildings or sites that have grown organically over time.
In these situations, SoftSol will assess the existing infrastructure, identify any deficiencies, and advise on practical remediation options. Bringing existing cabling into full alignment with the current standard is achievable, but it typically requires additional investment — which may include retesting, retermination, or partial recabling of affected runs. SoftSol will always recommend the most cost-effective path to a compliant and reliable infrastructure.
