The difference between cca vs. solid copper lies in how the conductor wire itself is constructed. a cca cable conductor is copper coated aluminum. this has the following effects upon the cable: cca cable is brittle and not tolerant of bends. interestingly, merely pulling it off the reel or out of the box might break the conductor (s) due to far.
The wireshark oui lookup tool provides an easy way to look up ouis and other mac address prefixes. it uses the wireshark manufacturer database, which is a list of ouis and mac addresses compiled from a number of sources. type or paste in a list of ouis, mac addresses, or descriptions below. ouis and mac addresses may be colon , hyphen , or. The three metals are copper, aluminum and copper clad aluminum (cca), also known by the acronym cu clad when applied to an electrical conductor. over its entire life cycle, cu clad has seen very limited installation in only a handful of us municipalities from 1972 – 1980. since 1980, cu clad has been absent from the us market. Solid copper provides better and faster signals. it produces less heat. it’s also more flexible, making it better for long distance or sharp bending cable runs. the only advantage of cca is cost, and if your overall ethernet network includes less than 100 meters of cabling, the cost savings of cca will be minimal. Uv vis diffuse reflectance spectra of the prepared samples are shown in fig. 4. it can be seen that cu btc is not strong enough to absorb visible light and ultraviolet light. p25 absorbs strongly.

Szukając na necie kabla utp stp do mojej sieci znalazłem jakieś takie kable dosyć tanie bo po 150 za karton 305m cca 24awg czyli aluminium miedziowane. w porównaniu z czystą miedzią jest jakaś różnica w jakości sygnału, zakłóceniach, trwałości kabla bo jak dam pod tynk to z 30 lat będzie leżeć. gdzieś tu na forum znalazłem.
