SCTE sets standard for MoCA 2.0 and DOCSIS 3.1 interoperability

SCTE 235 seeks to prevent degradation or failure of signals due to a shared frequency range of above 1 GHz.

The SCTE has announced a new set of standards designed to ensure interoperability between the MoCA 2.0 and DOCSIS 3.1 specifications. 

Labeled “Operational Practice for the Coexistence of DCOSIS 3.1 Signals and MoCA Signals in the Home Environment,” SCTE 235 seeks to prevent degradation or failure of signals due to a shared frequency range of above 1 GHz.

The SCTE 235 operational practices outline proper use of frequencies and filters for network operators to optimize performance in environments that include both DOCSIS 3.1 and the Multimedia over Coax Alliance’s MoCA 2.0 specification. 

The expansion of the DOCSIS RF spectrum above 1.2 GHz created shared frequencies and other potential conflicts within the 1125-1675 MHz for DOCSIS 3.1 and MoCA technology. SCTE 235 prescribes the necessary isolation and proper locations and required performance of filters to ensure there is no signal leakage between residences, or overloading of DOCSIS and MoCA receivers. 

“As cable system operators expand their service portfolios, a key role for SCTE/ISBE standards is to ensure that our members can continue to leverage all available technologies,” said Dean Stoneback, senior director of engineering for the Society of Cable Telecommunications Engineers, in a statement. “By working collaboratively with CableLabs and organizations such as MoCA, we can drive solutions that can increase cable’s competitive edge and create value for the consumers the industry serves.”

“The multiyear effort to assure the coexistence of DOCSIS 3.1 and MoCA has successfully resulted in operational practices that enable the optimal performance of both technologies when deployed in home environments,” added Ralph Brown, CTO of CableLabs. “SCTE 235 illustrates the value of CableLabs’ close collaboration with MoCA and SCTE/ISBE.”
