MHz is the frequency or rate at which a wave will cycle per second. 1 Megahertz would be equal to 10^6 Hertz or 1 million cycles per second.
Mbps refers to the how many bits of data is transmitted trough a media (such as fiber optic cable) per second.
MHz and Mbps are not equal, the confusion occurs because MHz works with analogue signals while a data transfer occurs digitally.
Transferring data rate (Mbps) to a cable is dependent upon encoding techniques. “Manchester” encoding is used for Standard Ethernet (10 Mbps), which is a two-level encoding technique that requires a minimum of 10 MHz. Cat3 copper cable offers 16 MHz and is why it was acceptable for Standard Ethernet.Read More
