In an ungrounded home environment, it is generally recommended to use unshielded Ethernet cables (U/UTP) rather than shielded types such as U/FTP or S/FTP.
1. Shielded cables have a metal shielding layer that is designed to divert electromagnetic interference (EMI) safely to ground. If the cabling system is not properly grounded, the shield cannot discharge this interference and may instead act like an antenna, collecting noise and creating a new source of interference that can degrade signal transmission.
2. In addition, without a reliable ground path, electrostatic discharge (ESD) and power surges cannot be effectively dissipated through the shield. This not only reduces the protective benefit of shielding, but may also increase the risk of equipment damage. So, for typical ungrounded residential environments, a high‑quality unshielded cable is usually the safer and more appropriate choice.

The standardized bandwidth for Cat6a cable is 500 MHz, as defined by international cabling standards. Any Cat6a‑compliant cable is tested and certified to meet performance requirements up to this frequency. A 550 MHz value usually indicates the cable’s maximum tested or characterized bandwidth, showing that it performs beyond the minimum Cat6a specification, rather than representing a different or higher category. This extra margin is typically achieved through optimized cable design, higher‑quality materials, and stricter manufacturing control.

The selection of gauge mainly depends on the cabling length, flexibility requirements and PoE power supply requirements.
1. It is recommended to use 24 AWG jumper cables in long-distance connections and PoE/PoE+/PoE++ applications, as their lower resistance helps to enhance power supply efficiency and transmission stability.
2. If the PoE power supply requirement is low and higher flexibility and easier cable management are needed, then 26 AWG or 28 AWG cables are more suitable for short-distance connections.
3. For Cat6a links that carry PoE or high-power PoE, 24 AWG cables offer better heat dissipation and electrical margin, while the thinner specifications are more suitable for short-distance and low-power connections.

We offer cables with PVC, LSZH (Low Smoke Zero Halogen) and other jacket materials. PVC jackets are flexible and durable. LSZH jackets emit very low levels of smoke and toxic fumes when burned, making them safer and often mandatory in confined spaces like data centers or public transportation vehicles.
