As a key component of Motorola’s RFoG solution, the ONU190 RFoG Optical Network Unit adds return-path RF transport capability to a passive optical network (PON), supporting the seamless delivery of existing voice, video and broadband services over a common infrastructure. In order to enable upstream data or service requests from an RF set-top box or cable modem, the ONU190 injects upstream data onto the PON and serves as the optical transport layer for DOCSIS® and DAVIC technologies. The ONU190 operates with industry standard return path receivers and Cable Modem Termination Systems (CMTS), eliminating the need for costly network upgrades.
