EMCORE G1832 RFoG Optical Networking Unit (ONU) Transceiver

EMCORE’s G1832 Radio Frequeny over Glass (RFoG) Optical Networking Unit (ONU) Transceiver is an OBI (Optical Beat Interference) mitigated design, utilizing EMCORE’s breakthrough Linear Externally Modulated Laser (L-EMLTM), that extends Hybrid Fiber Coax (HFC) networks deeper into neighborhoods to handle increasing user bandwidth demand. It enables cable operators to offer a Fiber-to-the-Premise (FTTP) type architecture without changes to their standard equipment. It supports 1610 nm burst mode analog return-path conversion for voice, video and data signals in single family and multi-dwelling unit applications. The G1832 RFoG resides at the customer’s location and provides the interface between the optical network and the subscriber coaxial network.

EMCORE’s RFoG ONU transceiver is designed to support standard CATV downstream and upstream transmission bands. Downstream it receives a 1550 nm forward path optical signal carrying an RF cable television spectrum up to 1.2 GHz, making it compatible with the cable industry’s DOCSIS 3.0 and 3.1 standards. For return path it utilizes an L-EMLTM transmitter that operates at 1610 nm and supports a 5-85 MHz spectrum. EMCORE’s OBI mitigated RFoG ONU is compliant with the SCTE (Society of Cable Telecommunications Engineers) RF over Glass specification.
