Fiber Weak Explosion: Cable Network Speed ​​Can Soar to 10 Gbps
For radio and television, if the cable network is well utilized, then the speed of the second fiber becomes comparable.
According to BGR, CableLabs has just made a groundbreaking announcement—introducing full-duplex DOCSIS standard cable modems that can achieve up to 10Gbps in both upstream and downstream speeds. This development is truly mind-blowing and could revolutionize how we access high-speed internet.

CableLabs also highlighted that upgrading existing cable TV networks to support full-duplex DOCSIS is remarkably straightforward. All it takes is replacing or updating the equipment at the central office and the user end—no need to replace the cables themselves. This makes the transition both cost-effective and efficient.
If this technology is widely adopted, the need for fiber-optic infrastructure might become less critical. People might start questioning whether fiber is still necessary when cable networks can deliver such incredible speeds. It's a game-changer that could reshape the future of broadband connectivity.

This advancement not only boosts performance but also opens new possibilities for streaming, online gaming, and remote work. With such high bandwidth available through traditional cable systems, the digital divide may narrow significantly, bringing faster internet to more people without the need for expensive fiber installations.
