What is a Docsis 3.1 Modem?

DOCSIS is actually an acronym which stands for Data Over Cable Service Interface Specification and it is an international standard that is being used to transmit data through cable systems and this made it possible for any types of the cable modem to be functioning well with any types of cable systems. 

The DOCSIS 3.1 may support such a fast speed of up to 10 Gigabits per second which is a speed that can only be achieved by using a connection that uses a fiber optic cable. 

By using a modem which support DOCSIS 3.1 alone does not promise an internet speed of up to 10 Gigabits per second however if DOCSIS 3.1 is being supported at the end of both of the cable connection then it may be possible to get such a spectacular internet speed and grants a perfect chance for the cable service provider to take into account this technology.
