Local availability, built for real projects
When a classroom, lab or site install needs reliable network leads today, waiting weeks for imports is not an option. Communica keeps a broad range of computer network leads in stock across South Africa so you can get the right cable, connector and accessory the same day or on short lead times. We focus on practical fit-for-purpose ranges - patch leads for desktop and rack, pre-terminated runs for PoE devices, and bulk UTP for structured cabling - with VAT invoicing and branch collection from Samrand, Pretoria CBD or Cape Town to suit procurement and education budgets.
Which cable should you pick?
Selection starts with how you use the cable: short patching, wall-to-switch runs, PoE power delivery, or future-proofed backbone links. Below is a compact comparison to help you decide quickly without endless datasheet hunting.
| Type | Typical Use | Max Speed | Shielding |
|---|---|---|---|
| Cat5e | Desktop patching, short runs | 1 Gbps | UTP |
| Cat6 | Patch & short horizontal | 1-10 Gbps (short) | UTP/STP options |
| Cat6a | Racks, PoE+, future-proof | 10 Gbps | UTP/STP |
Practical spec callouts
Look beyond the category number: stranded vs solid conductors, booted RJ45s for high-traffic desks, snagless boots for patch panels, and whether the lead is certified for PoE temperature rise. Communica stocks both pre-made patch leads and bulk drums so you can mix patch panels with pre-terminated leads for fast installs.
Compatibility and accessories
Most modern switches and NICs accept Cat5e and above, but for reliable 10 Gbps or long PoE runs choose Cat6a and proper shielded connectors if your environment has EMI concerns. Accessory bundles we commonly recommend include RJ45 crimp tools, cable testers, modular boots and labelled patch panels for tidy racks.

For field terminations use a basic continuity tester and an RJ45 crimper; for long runs use permanent solid-core cable and punch down on a keystone or patch panel.
