These cables are commonly used in structured cabling systems for Gigabit Ethernet, voice, video, and security applications. The outer jacket is available in PVC for standard use or LSZH (Low Smoke Zero Halogen) for safer installations in enclosed or fire-prone environments. Cat 6 is also backward compatible with Cat 5 and Cat 5e systems, making it a versatile and future-proof choice for modern networks that demand consistent speed, low latency, and high performance. Additionally, Cat 6 cables come in shielded (STP) and unshielded (UTP) variants. Shielded cables provide extra protection in environments with high electromagnetic interference, such as factories or near heavy machinery, while unshielded types are suitable for general office and home use. Proper termination and installation are crucial to maintaining Cat 6 performance, and when installed correctly, they offer excellent network stability and reduced signal loss.
