  • CAT5e EIA/TIA-568 rating supports standard twisted-pair network speeds
  • Compact 4.5 mm diameter cable fits tight routing spaces
  • Lightweight 35 g build adds minimal strain to ports
  • Connects adapters, switches, routers, modems and patch panels

30 cm CAT5e Extension Cable

This 30 cm CAT5e cable provides a short male-to-female link for Ethernet networks. It uses RJ45 8P8C connectors wired to the EIA/TIA-568 Category 5e standard. The 4.5 mm diameter cable weighs 35 g and measures 39 cm end-to-end. It suits LAN connections between adapters, switches, routers, modems and patch panels.

Installers Needing a Short Reach

The 30 cm length works well for tidy rack patches or desk-side extensions where slack is unwanted. Builders who need a longer run across a room or between floors should look at a different cable. The fixed male-to-female orientation also means it cannot join two male patch leads directly.

EIA/TIA-568 Category 5e Compliance

This standard defines the performance ceiling for crosstalk and attenuation on the link. If your installation requires Category 6 or higher bandwidth, this cable will not meet that specification. Verify the category rating your network equipment demands before purchasing.

Questions about this item

How do I install the 30 cm RJ45 male-to-female cable, and what step is often missed?

Plug the male 8P8C plug into the switch or router port, then seat the female jack fully onto the device cable until the latch clicks; the common mistake is leaving the latch unclicked, which causes intermittent contact.

What maintenance or replacement will this 30 cm Cat5e patch cable need later?

Inspect the 4.5 mm jacket and RJ45 contacts periodically; replace the cable if the latch tab breaks, the conductors kink near the plugs, or corrosion appears on the gold-plated pins.

What limit appears first on this 30 cm Cat5e link under sustained load?

The EIA/TIA-568 Category 5e rating governs the maximum supported frequency and crosstalk budget, so the cable’s own length is not the bottleneck — the standard’s channel limits are.
