Nokia Bell Labs Hits 10 Gbps Symmetrical with XG-Cable

Nokia Bell Labs has demonstrated a prototype XG-CABLE solution that achieves full duplex 10 Gbps rates over a traditional Hybrid Fiber Coax (HFC) cable systems and based on CableLabs' DOCSIS 3.1 architecture.


Specifically, the XG-CABLE test used two different cable scenarios:

  • Leveraging a point-to-point 100m coaxial drop cable, XG-CABLE was able to deliver 10 Gbps symmetric data speeds with 1.2 Ghz of spectrum 
  • Using HFC network topologies that utilize a Fiber-to-the-Last-Amplifier (point-to-multipoint coax drop) approach, XG-CABLE was able to deliver 7.5 Gbps of symmetrical data speeds.

Nokia Bell Lab's XG-CABLE utilizes innovative echo canceling technologies developed by Bell Labs to achieve full duplex transmission of 10 Gbps upstream and 10 Gbps downstream simultaneously.

"The XG-CABLE proof of concept is a great example of our ongoing effort and commitment to provide the cable industry with the latest innovations and technology needed to effectively address the growing demand for gigabit services. The proof of concept demonstrates that providing 10 Gbps symmetrical services over HFC networks is a real possibility for operators; it is an important achievement that will define the future capabilities and ultra-broadband services cable providers are able to deliver," stated Federico Guillén, President of Fixed Networks, Nokia.

A whitepaper is posted online.
