Description:
Category 3 cable, or CAT3 cable is a type of twisted pair cable frequently used in voice and data applications. Phone cable is defined by the Electronic Industry Alliance (EIA) and Telecommunication Industry Association (TIA). HUIER Cable's CAT3 phone cable is quality manufactured to meet and/or exceed product certifications and standards for EIA/TIA 568 and ISO/IEC 11801 specifications.


This type phobe cable is flat which is easy for install in angusty spaces.

Flat cable has been around for about 60 years, since Cicoil invented the ribbon cable for IBM computers in 1956. Over the decades it has been a favorite in high end computing, military and aerospace, robotics and motion control devices. Its advantages include superior flexibility, electronic noise abatement, and packaging efficiency. Its limiting factor over this time has been the need for unique termination techniques—prepping for connectors has largely required hand work. A new type of flat cable has been developed by Cicoil Corporation that promises to put this last hurdle into the past, opening the potential for engineers to take advantage of flat cable advantages while using the common cable prep tools and automated processes currently in use with round cables.

Flat versus round
Most cable is round, which is a generally useful geometry. Examine an ordinary round electrical cable and you’ll typically find insulated wires in a bundle surrounded by several layers of other “filler” material. These layers are there to retain a round profile and to minimize frictional heating as the cable moves. Surrounding the wires and fillers is an outer jacket that holds it all together and provides some level of protection against outside elements. But, while round cable is normally fine for general use, there are drawbacks with this construction.


Because it incorporates these multiple layers of wires, insulation, and fillers, heat dissipation from the wires can be problematic in round cable. Despite measures to reduce it there is still frictional heat produced inside the cable during repetitive motion cycles. Add to this the issue of electrical impedance alteration as conductors inside the cable move relative to one another.

With flat cable each conductor is kept parallel with neighboring conductors to form the flat profile. Unlike round cable, conductors in flat cables don’t move within the encapsulating jacket so their electrical qualities remain constant. Similarly, the conductors in the cable all have the same physical and electrical length. Thus signal skewing and differential time delays between signals in the cable stay at a minimum.
