MoCA Installation Guidelines
MoCA is an in-home distribution technology that leverages the coax cable networks
that exist in more than 90% of US households. MoCA is an attractive option because
it provides a relatively low-cost method of getting DVR and other multimedia
sharing video services to multiple TVs within the home without additional cable
installation.
MoCA operates over the physical layer of the home coaxial cable plant in the 1000-
1500 MHz spectrum. Its infrastructure begins at the service provider’s drop cable at
the first passive splitter connected to the home coax network.
Recommended Installation Guidelines
The following guidelines are recommended for a home network prior to installation.
The maximum cable distance supported between the network coordinator and
the last outlet is 300 feet.
The maximum attenuation permitted between nodes is 25 dB.
Branches within the home-network should flow from secondary splitters.
Assess the home network and determine the data rates between coax outlets.
Sectionalize the individual MoCA nodes to validate proper operation of the
device’s MoCA interface.
Evaluate and certify the integrity of the coax cable plant between MoCA nodes.
