Network cable comes with different ratings, either 'CM', 'CMR' or 'CMP', as well as 'UL'. These cable rating codes mean that the cables meets different UL-NEC requirements based mostly on cable jacket quality concerning fire hazard.
CM: CM rated cables are used for general building wiring including residential installation. These cables are resistant to the spread of fire and pass the UL 1581 Vertical Tray Flame Test. When it's just called a patch cable, it is typically CM rated jacket.
CMR: The 'R' in CRM is for 'Riser'. Riser type cables are engineered to prevent the spread of fire from floor to floor and are suitable for vertical shaft applications.
CMP: The 'P' in CMP is for Plenum. Cables meeting type CMP requirements are suitable for installation in ducts and plenums without the use of conduit. These cables are designed for fire resistance and low-smoke and toxin producing characteristics.
In general, fire resistance requirement becomes higher in this order; CM ->CMR ->CMP. CMP produces the least smoke and toxic fume when burnt.
Typical patch cables are CM rated and suitable for general building installation. Our CMR series specifically uses CMR rated jacket for installations where higher fire resistance is required.

| TIA/EIA is abbreviation of Telecommunication Industry Association and Electronics Industry Alliance that sets telecommunication standards in the US. BestLink Netware patch cable complies with the latest TIA/EIA telecommunication cable standards. |

|
| There are two standards for wiring color code, 5???68A and 568B. While there's no difference in connectivity between 568A and 568B, 568B is the most prevalent wi ring color code in the US. Our patch cable is 568B wired. |

|
| UTP is Unshielded Twisted Pair and STP is Shielded Twisted Pair. STP cable is wrapped in metal foil or braid. Both have the same Ethernet communication performance, but STP has better protection against Electro-Magnetis noise from outside. UTP is accepted for residential and general commercial installation. |

|
| AWG (American Wire Gauge) indicates wire thickness. Higher the number, thinner the wire. 24AWG or 26AWG is commonly used for ethernet cables. Stranded wire is a bundle of thin wires as oposed to solid wire that is single solid wire. Stranded wire is more flexible than solid wire and commonly used for indoor network wiring such as patch cable. |
