Cat 5, cat 5e, cat 6 and cat 7 cables

 

Computer Wiring


The majority of offices rely on networked computers to carry out daily activities. J and J Electrical Services can install all types of structured cabling in your premises.

 

Category 5 (cat 5)

 

Cat 5 is short for category 5 computer network cable. It usually comprises of 4 twisted pairs of wires (copper) terminated by RJ45 connectors. The frequencies supported are up to 100 MHz. The usual use of category 5 cables is for networks with speeds of 10 to 100Mbps. That is, Ethernet and Fast Ethernet.


Category 5e (Cat 5e)

 

Cat 5e is an enhancement of a category 5 cable and supports data speeds of up to 1000Mbps (Gigabit Networks). Cat 5e cable will support Ethernet, Fast Ethernet, and Gigabit Ethernet. Cat 5e cables are backwards compatible, meaning that they can be used in any network instead of Cat 5 cable. Cat 5e also reduces the Crosstalk (electrical interference), which enables better quality of signal transmission. Category 5e has also a higher frequency of up to 350 MHz.

 

Category 6 (Cat 6)

 

Cat 6 cables are similar to cat 5 but are produced to higher standards.


Category 7 (Cat 7)

 

Category 7 like its predecessors is aimed at higher standards. The main differences are the isolation structure and connector type.

 

Why use an electrician to lay your network cable?


Because there are several technical limitations which can only be known when assessed by a qualified installer – i.e. the lengths of the cable (maximum 100meters or 328 feet). Contact J and J Electrical Services to find out more.
