CAT6 VERSUS CAT8 CABLES

BSRIA or Building Services Research and Information Association are a UK based organization that specializes in the construction and building services space.  According to BSRIA, while the Cat6 cable sales dominated the year 2018, the growth in the worldwide cabling market will continue to grow in the year 2019.

It is very important to educate yourself with the right kind of cable connections that you might require for your home or office, especially in terms of the need, specifications and limitations of each type of cable.  Else you might end up paying for highly priced or over-priced networking solutions that you might not even require.

Comcore Connexions or 3C3 as we are now known is a one-stop solution for various networking products, such as copper and fiber optic cables. The company offers totally integrated solutions to its clients, which helps them avoid approaching different vendors and purchasing each system separately.  We are not only one of the leading Cat6 Cable manufacturers in India, but are also considered as one of the top 10 fiber optic cable manufacturers in India.  Our range of products also includes Cat5, Cat5E, Cat7 and the latest Cat8 Cables.

What is a Cat6 Cable?

There are different kinds of Ethernet Cables.  They are Category 6 or Cat6 Cables, Category 7 or Cat7 Cables and Category8 or Cat8 Cables.  In a Cat6 Cable, there are 4 pairs of copper wires that support 10 Gbps of Ethernet connection.  35 – 55 Meters of cables are supported at a transmitting speed of 10 Gbps.  Signals of up to 250 MHz frequency are transmitted, which means that the signal passes so many number of times through the cables.  It uses the RJ-45 Standard Connector and is compatible to its previous versions of a Cat5 and a Cat5E Cable in a backward fashion.  In spite of the emergence of Cat8 Cables, Cat6 Cables continue to support the bandwidth requirements of end customers, data centers and gigabit networks.

What is a Cat8 Cable?

Cat8 or Category8 Cables are the next generation Ethernet Copper Cables that support a frequency of up to 2000 MHz, though it is limited to a 30-meter, 2-connector channel.  A shielded cabling is required for their usage, but the speed that they support can go up to 25 to 40 Gbps.  They look very similar to their lower category cables and can be terminated either in RJ-45 or non RJ-45 Connections.  Just like the Cat6 version, they are also compatible to previous versions in a backward manner.  They are specifically designed to be used at data centers where high intensity server-to-switch bandwidth connections are made.
