UTP Cable Rating Codes

UTP cables meet different UL-NEC requirements based on cable-jacket quality. Below is an explanation of the rating codes for each cable type.

UL – The National Electrical Code (NEC), published by the National Fire Protection Association (NFPA), details advisory safety considerations for electrical wiring. NEC Article 800 Communications Cables are manufactured to meet these different cable types.

1.CMP – Cables meeting type CMP requirements are suitable for installation in ducts and plenums without the use of conduit. These cables are designed for re resistance and low-smoke producing characteristics.

2.CMR – Riser type cables are engineered to prevent the spread of re from oor to oor and are suitable for vertical shaft applications.

3.CM – Cables for general building wiring. CM cables are used in areas other than plenums and risers. These cables are resistant to the spread of re and pass the UL 1581Vertical Tray Flame Test.

4.MP, MPR & MPP – Within Article 800, the Multi-purpose Cables Category allows conditional substitutions between different cable types & are restricted by number, AWG size and stranding of the cable conductors.

Terms You Should Be Familiar With

1.BACKBONE WIRING – The physical/electrical interconnections between telecommunications closets and equipment rooms.

2.COMPLIANCE – A wiring device that meets all characteristics of a standard is said to be in compliance with that standard.

3.PREMISE WIRING – The entire wiring system on the premises especially the supporting wiring that connects the communications outlets to the network interface jack.

4.NEAR-END CROSSTALK (NEXT) – In wires packed together within a cable, the signals generated at one end of the link can ush out the weaker signals coming back from the recipient.
