CAT 5E Bulk LAN Cable CAT5E

Category 5E (Enhanced) Operates at up to 350 MHz, instead of the 100 MHz of standard CAT 5 cables. These CAT 5E cables are fully ANSI/TIA/EIA 568 B.2-1 compliant. CAT 5e cables are compatible with the current Category 5E Equipment, as well as Legacy and CAT 5. The Enhanced Electrical Performance of CAT 5E cables ensures capacity in supporting increased Bandwidth Application Requirements. Typical applications would include, Gigabit Ethernet, Distributed Video (CCTV) ;over CAT 5E, Voice over IP (VoIP). These CAT 5E cables offer Excellent Performance in all aspects of Data Transmission such as Frequency, Attenuation, Impedance, Capacitance, Resistance, and NEXT Level Performance. 




UTP (unshielded twisted pair) cables are found in many Ethernet networks and telephone systems. For indoor telephone applications, UTP is often grouped into sets of 25 pairs according to a standard 25-pair color code originally developed by AT&T. A typical subset of these colors (white/blue, blue/white, white/orange, orange/white) shows up in most UTP cables. Typically, UTP would be used in an office setting.

STP (shielded twisted pair) cable for environments with lots of potential interference, or if you must place cable in extremely sensitive environments that may be susceptible to the electrical current in the UTP, shielded twisted pair may be the solution. Shielded cables can also help to extend the maximum distance of the cables.

FTP (foiled twisted pair) cable contains multiple pairs of copper wire enclosed in a sheath of aluminum foil. It's used in wiring systems in buildings or other environments where heavy noise adjacent to the wire might cause interference. The foil provides insulation not afforded by UTP (unshielded twisted pair), the most common kind of structural wiring. The disadvantage of FTP is that it requires somewhat more care in "earthing" (grounding) than UTP and electrical impedances must be matched when connecting to UTP. Typically, FTP might be used in a factory setting.


Solid core cable is supposed to be used for permanently installed runs. It is less flexible than stranded cable and is more prone to failure if repeatedly flexed. Stranded cable is used for fly leads at patch panel and for connections from wall-ports to end devices, as it resists cracking of the conductors. Stranded core is generally more expensive than solid core.

Connectors need to be designed differently for solid core than for stranded. Use of a connector with the wrong cable type is likely to lead to unreliable cabling. Plugs designed for solid and stranded core are readily available, and some vendors even offer plugs designed for use with both types. The punch-down blocks on patch-panel and wall port jacks are designed for use with solid core cable.

UL 444 is the defining document by Underwriters Laboratories (UL) for communications cables.  It is in this standard that the categories CM (non-plenum, non-riser), CMR (riser-rated) and CMP (plenum-rated) originate as cable types and cable markings.  These categories are commonly used in many other diversified documents such as Article 800 of the NFPA 70 (NEC) and are printed on communications cables.  Note that other categories were also defined in UL 444.  These include MP (multi-purpose cable), MPR (multi-purpose riser cable), MPP (multi-purpose plenum cable), CMX (communications cable, limited use), CL1 and CL2.  CL1 and CL2 are often associated with signal and alarm cable.  The remainder are not used in normal communications cabling.   

UL 1581 applies to non-plenum, non-riser cable. 
UL 1666 applies to riser-rated cable.  
UL 910 (also known as the modified Steiner Tunnel Test) applies to plenum-rated cable.


CM - Cable meeting UL 1685 (UL 1581, Sec. 1160) Vertical-Tray, CSA FT1

CMG - Cable meeting CSA FT4

CMR - Cable meeting UL 1666, CSA FT4. This cable is used in vertical tray applications such as cable runs between floors through cable risers. Riser rated cable must self extinguish and must prevent the flame from traveling up the cable in a vertical burn test. Cable that is to be run between floors in non-plenum areas is rated as riser cable. The fire requirements on riser cable are not as strict. Thus, plenum cable can always replace riser cable, but riser cable cannot replace plenum cable in plenum spaces

CMP - Cable meeting CSA FT6 or NFPA 262 (UL 910). This cable can be installed in air plenums and ducts in accordance with NEC Article 800. A Plenum is a hidden space within a building which is used for HVAC (Heating, Ventilation, and Air Conditioning) Plenum cable is coated with a fire-retardant coating. Plenum cable must not burn easily and must not emit toxic fumes when exposed to extreme heat. Because of these requirements, plenum cable is more expensive than non-plenum cable. Plenum cable is jacketed with a fire-retardant plastic jacket of either a low-smoke polyvinyl chloride (PVC) {patented 1987} or a fluorinated ethylene polymer (FEP). Polyolefin formulations, specifically based on polyethylene compounding had been developed by at least two companies in the early to mid-1990s; however, these were never commercialized and development efforts continue in these yet-untapped product potentials. Development efforts on a non-halogen plenum compound were announced in 2007 citing new flame-retardant synergist packages that may provide an answer for an yet-under-developed plenum cable market outside the United States. All materials intended for use on wire and cables to be placed in plenum spaces are designed to meet rigorous fire safety test standards in accordance with NFPA 262 and outlined in NFPA 90A. Plenum-rated cables are restricted to only allow certain chemicals for manufacture of the wire insulation and cable sheath. Typically this results in reduced flexibility of plastic cables, making it stiff and hard to bend. The bend radius may also be increased, and tight bends can potentially crack or tear the insulation and sheathing.

CMXF - Cable meeting UL 1581, Sec. 1080 (VW-1), CSA FT1; Exterior Flooded Core is typically a UV resistant black jacket with the interior containing an anti-water migration medium for direct burial network installations.

CMXT - Cable meeting UL 1581, Sec. 1080 (VW-1), CSA FT1; Exterior Shielded cable is used in environments were extra protection from outside interference is needed. This can be heavy machinery, transformers, generators or other equipment that has a high degree of EMI. (Electro Magnetic Interference) .

CMH - Cable meeting CSA FT1.

FT1 Vertical Flame Test - per C.S.A. C22.2 No. 0.3-92 Para 4.11.1

A finished cable shall not propagate a flame or continue to burn for more than one (1) minute after five (5) fifteen (15) second applications of the test flame. There is an interval of fifteen (15) seconds between flame applications. The flame test shall be performed in accordance with Para 4.11.1 of Canadian Standards Association (CSA) Standard C22.2 No. 0.3. In addition, if more than 25% of the indicator flag is burned, the test cable fails. FT1 Cables can be used in Combustible buildings.


FT4 Vertical Flame Test - Cables in Cable Trays per C.S.A. C22.2 No. 0.3-92 Para 4.11.4

Is similar to the UL-1685 Vertical Tray Flame Test, but is more severe. The FT4 test has its burner mounted at 20° from the horizontal with the burner ports facing up. The UL-1685 Vertical Tray has its burner at 0° from the horizontal. The FT4 samples must be larger than 13mm (.512″) in diameter. If not, then the cable samples are grouped in units of at least three (3) to obtain a grouped overall diameter of 13mm. The UL-1581 Vertical Tray does not distinguish on cable size. The FT4 has a maximum char height of 1.5 m (59″) measured from the lower edge of the burner face. The UL-1685 has a flame height allowable up to approximately 78″ measured from the burner. FT4 Cables can be used in Non-Combustible buildings.

FT6 Horizontal Flame & Smoke Test - per C.S.A. C22.2 No. 0.3-92 Appendix B
