There are three types of network cables.
Type cm network cable.
Cat 6 is the sixth generation of twisted pair ethernet cabling that is used in home and business networks.
The differences between the various types of ethernet cables are rather simple but some of the terminologies can be confusing.
Cmr cable is also referred to as riser rated cable.
Cm cmg are the most commonly used commercial grade communication cable.
To help out we put together a quick rundown on what the different.
Cable twisting length is not standardized but typically there are 1 5 2 twists per cm in cat 5 e and 2 twists per cm in cat 6.
It can be used when cables need to be run between floors through risers.

Understanding cable jacket ratings.
It is a cable jacket fire resistance rating defined in article 800 of the nec.
The ethernet cables that are labeled type cm must pass a standardized flammability test before the cables are put into use.
In the case of cm the standard outlines general use or use in cases where the fire code does not place any restrictions on cable type.
Cl cm cmr and cmp so you need some cable to run for a new ethernet or home theater in your home and you know exactly what type and length of cable you need 50 feet of cat6 cable 15 feet of high speed hdmi cable whatever it might be.
Within a single cable each colored pair will also have different twist lengths based on prime numbers so that no two twists ever align.
Cmr cable often called riser rated cable is constructed to prevent fires from spreading floor to floor in vertical installations.
This tutorial explains the types of network cables used in computer networks in detail.
Cat 5 is also used to carry other signals such as telephony and video.
Set the wayback machine to the late 1980s.
Category 5 cable cat 5 is a twisted pair cable for computer networks since 2001 the variant commonly in use is the category 5e specification cat 5e the cable standard provides performance of up to 100 mhz and is suitable for most varieties of ethernet over twisted pair up to 1000base t gigabit ethernet.
Cat 6 cabling is backward compatible with the cat 5 and cat 5e standards that preceded it.
Cmr cable stands for communications multipurpose cable riser.
Such cables are limited to residential or other small applications where the number of communication cables used is very little.
Cmx is a residential grade cable.
