Trinity Communications is installing an RFoG network based on equipment from Arris and has launched a digital triple play in its markets in Tennessee.

Components of the RF over glass deployment include Arris' CorWave II multi-wavelength forward transmitters, FTTMax RFoG optical network units (ONUs) at the customer premises, and the TransMax RFoG Repeater for Optical Amplification of RFoG wavelengths.

When completed, the deployment will offer triple-play services to approximately 3,000 homes and businesses, spanning more than 200 miles of fiber-optic plant. Trinity Communications operates systems in and around South Pittsburgh, Tenn.

"We selected the Arris CorWave and RFoG solutions because of their proven reliability and to meet our capital and operational budgetary needs," said Trinity Communications President James Gee. "In our system, population density is low and spread out, so the RFoG cost model and return on investment is very attractive to us. Once the backbone is in place, we can simply drop a fiber to the residential or small business customer, install the RFoG ONU and they're set."

RFoG enables an operator to continue to leverage its DOCSIS-based infrastructure, enabling cable operators to use their existing headend infrastructure, current provisioning systems and CPE devices.

RFoG has been demonstrated to be particularly cost-effective for serving businesses, community hubs and residences in low-density areas. In part, Arris said, this is due to the reduced outside plant maintenance and lower power consumption. RFoG is a point on a migration path to technologies such as EPON.
