GigaTrue Premium CAT6 patch cable

This 25 ft unshielded twisted-pair cable is tested to 550 MHz, exceeding the 250 MHz CAT6 standard. It uses 24 AWG conductors with 50-micron gold-plated contacts for reliable conductivity. Snagless boots protect the RJ45 connectors during installation and removal. ETL verification confirms compliance with ANSI/TIA-568-C2.

Suited for Gigabit Ethernet and PoE runs up to 25 ft

Ideal for 1000BASE-T, 100BASE-TX and 10BASE-T links where a single blue patch lead is required. The 750-cycle connector rating supports frequent re-patching in rack or wall-plate environments. Not for buyers who need shielded cable for high-EMI areas, outdoor burial rating or lengths beyond 25 ft.

Tested to 550 MHz bandwidth

This single figure shows the cable surpasses the baseline CAT6 requirement by a wide margin, delivering headroom for 1 Gbps signals and reduced near-end crosstalk. If your installation demands verified 550 MHz performance, this part meets it; if you only need the minimum 250 MHz spec, a standard CAT6 cable will also work.

Questions about this item

How do I plug the RJ45 connectors in without breaking the snagless boots?

Hold the boot and push the connector straight in until it clicks; pulling on the cable instead of the boot is the step that tears the snagless tab off.

When will the 50-micron gold-plated contacts need replacement?

The connectors are rated for 750 insertion and extraction cycles, so replacement depends on how often you unplug and reconnect the cable.

What performance limit appears first on a 25 ft run at 550 MHz?

The cable is tested to 550 MHz and ETL verified to ANSI/TIA-568-C2, so the 550 MHz bandwidth ceiling is reached before any length-related signal loss on this 25 ft patch cord.
