EMCORE Launches OBI Mitigated RFoG Optical Networking Unit Transceiver

ALHAMBRA, CA — EMCORE, a provider of advanced mixed-signal optics products that provide the foundation for high-speed communication network infrastructures and defense systems, announced the introduction of its new Radio Frequency over Glass (RFoG) Optical Networking Unit (ONU) Transceiver. EMCORE’s RFoG ONU is an OBI (Optical Beat Interference) mitigated design utilizing the company’s Linear Externally Modulated Laser (L-EMLTM).

RFoG technology enables cable operators to offer a fiber-to-the-premise (FTTP) type architecture without changes to standard equipment in the headend or central office. The RFoG ONU resides at the customer’s location and provides the interface between the optical network and the subscriber coaxial network.

Supporting Standard CATV Downstream and Upstream Transmission Bands
EMCORE’s RFoG ONU Transceiver is designed to support standard CATV downstream and upstream transmission bands for triple-play voice, video and data signals in single family and multiple-dwelling unit applications. 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 3.1 standard. For return path, it supports digital upstream transmission utilizing an L-EMLTM transmitter operating at 1610 nm that supports a 5-85 MHz spectrum. EMCORE's RFoG ONU is compliant with the SCTE (Society of Cable Telecommunications Engineers) RF over Glass specification.

EMCORE’s RFoG achieves OBI mitigation through proprietary upstream laser wavelength management. It features 6KV surge withstand on all coax ports, less than 1.0 μs upstream laser activation/deactivation time with low idle state power usage, and is UL, EMC and FCC part 15B compliant.
