Examples of various categories & types of network Cables


Category, (CAT) 5/5E Cable 

Category, (CAT) 6 Cable

CATEGORY-6 Cabling

CAT-6 cabling is installed in the same manner as CAT-5E cabling, and looks virtually identical, still providing the flexibility of a structured cabling system.

Cat-6 is the cable standard for Gigabit Ethernet and other network protocols that are backward compatible with the Cat-5E and earlier cable standards.

Cat-6 features stringent specifications for crosstalk and system noise. The cable standard provides performance of up to 250 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T / 1000BASE-TX (Gigabit Ethernet) and 10GBASE-T (10-Gigabit Ethernet). 

Category 6 cable has a reduced maximum length when used for 10GBASE-T. 

Cat- 6a cable, or "Augmented" Cat 6, operates to 500 MHz and has improved crosstalk characteristics, allowing 10GBASE-T to be run for the same distance as previous protocols.

CAT-6 cabling can cost up to 30% more than equivalent CAT-5E cabling systems. If you need advice on cabling or a free phone cabling survey, please call us at:

CAT-5 & CAT-5E Structured Cabling

KCCi has installed Structured cabling systems in thousands of businesses throughout United States. Structured cabling systems provide a convenient and easy method of managing the connection and relocation of voice and data devices.

Modern telephone systems are designed to be fitted within the CAT-5 communications cabinets in the phone room, along with ethernet switches and other netwoking equipment.

The telephone extensions can be "patched" to thier locations in the same manner as computers, making it easy for IT managers to re-patch devices when staff relocate, without having to reconfigure the phone system or add more cabling.

Most CAT-5 cables are unshielded, referred to as unshielded twisted pair (UTP). The twisted pairs reduce noise and improve signal and data quality. 

Category 5 was superseded by Category 5E to support ethernet networks with data transfer speeds up to 155 Mb/s, with a maximum distance for each CAT-5E cabling of 90m.
