Problems solved by technology

But correspondingly, the head-end equipment of Cable Modem is very expensive, and each head-end equipment can only carry a certain number of Cable Modems, so when the number of users is large, more head-end equipment will be invested, so this method is adopted The investment is also very large

And because HFC has a tree structure, the interference of various household appliances in the user's home will be collected to the front end through the cable, that is, the "funnel effect". When there are many users, it will seriously affect the communication quality and even cause normal communication.
