UTP stands for "unshielded twisted pair." It is a cable type with one or more pairs of twisted insulated copper conductors contained in a single sheath. UTP cables are the most common type of cabling used in desktop communications applications.

Cat6 standard is designed for Gigabit Ethernet and is backward compatible with Cat5e. The general difference between Cat5e and Cat6 is on performance abd bandwidth. Cat6 standard requires better insertion loss, return loss, NEXT and ELFEXT.Cat6 standard also push bandwidth from 100 Mhz for Cat5e to 250Mhz.

Channel Performance Characteristics:
Parameter	CAT 5e 100 MHz	CAT 6 100 MHz	CAT 6 250 MHz
Attenuation	24.0dB	21.3dB	36.0dB
NEXT	30.1dB	39.9dB	33.1dB
PSNEXT	27.1dB	37.1dB	30.2dB
ELFEXT	17.4dB	23.2dB	15.3dB
PSELFEXT	14.4dB	20.2dB	12.3dB
Return Loss	10.0dB	18.6dB	8.0dB

Optical Fiber Nonconductive Riser (OFNR) this type of cable contains only class fiber and no copper conductive elements.

It is usually used for vertical runs between floors.Optical Fiber Nonconductive Plenum (OFNP) contains glass and no copper conductive elements also but its purpose is usually for horizontal runs especially within an air handling conduit.

Cabling standard defines one pair of conductors as transmit pair and one pair of conductors for receive pair. When terminal devices are connected to a switch or hub, the cross over is done internally within the switch or hub, the cross over are done internally without a hub or switch, a crossover cable must be used.

10BaseT and 1000BaseTX crossover only require crossing of Pin 1/2 with Pin 3/6. For Gigabit crossover, T4 crossover is required. In addition of crossing Pin 1/2 with Pin 3/6, Pin 4/5 must cross with Pin 7/8. T4 crossover is backward compatible for 10BaseT and 1000BaseTX crossover.

RJ45 Connector or RJ45 plug is used commonly to refer to any 8P8C modular plug.

10BASE-T is the IEEE standard that defines the requirement for sending information at 10 Mbps on unshielded twisted-pair cabling, and defines various aspects of running Ethernet on this cabling.

100BASE-T is the IEEE standard that defines the requirement for sending information at 100 Mbps on unshielded twisted-pair cabling, and defines various aspects of running baseband Ethernet on this cabling.

1000BASE-T is the IEEE standard that defines the requirement for sending information at 1000 Mbps on unshielded twisted-pair cabling, and defines various aspects of running baseband Ethernet on this cabling.

PLEASE NOTE:
Normally an A-N switch will be detected and set to Full-duplex where a dual-speed hubs will be detected and set to Half-Duplex.

RoHS was adopted by the European Union in February 2003 as the Directive on the Restriction of the Use of Certain Hazadous Substances in Electrical and Electronic Equipment 2002/95/EC or commonly known as the Restriction of Hazadous Substances Directive.  RoHS took effect on July 1st, 2006 and it become lw for EU countries to restrict the use of six hazadous materials in electronic and electrical equipent manufacturing.  The six substances restrict by RoHS are Lead, Mercury, Cadmium, Hexaval Chromium, Polybrominated Biphenyls and Polybrominated Diphenyl Ether.

Cablesys is RoHS compliant on our cable offering.  Please contact your sales or customer service for further assistance.
