What is the difference between Cat5 and Cat6 Ethernet cables?
The main difference between Cat5 and Cat6 Ethernet cables lies in their bandwidth and frequency. Cat5 cables have a bandwidth of up to 1 Gigabit per second and a frequency of 100 MHz, while Cat6 cables have a bandwidth of up to 10 Gigabits per second and a frequency of 250 MHz. This means that Cat6 cables can transmit data at a much faster rate than Cat5 cables.
In addition to their differences in bandwidth and frequency, Cat5 and Cat6 cables also have different levels of shielding and twist rates. Cat6 cables typically have better shielding and tighter twist rates, which help to reduce electromagnetic interference (EMI) and improve signal quality. This makes Cat6 cables a better choice for applications where high-speed data transmission is critical, such as in commercial or industrial settings.
What is the maximum length of an Ethernet cable?
The maximum length of an Ethernet cable depends on the type of cable and the application in which it is being used.
