EMCORE to Introduce New RF over Glass Optical Networking Unit Transceiver

EMCORE Corporation has announced the introduction of its revolutionary new Radio Frequency over Glass (RFoG) Optical Networking Unit (ONU) Transceiver. The RFoG ONU is an OBI (Optical Beat Interference) mitigated design utilizing the company’s breakthrough Linear Externally Modulated Laser (L-EML). EMCORE will be showcasing the RFoG ONU at ANGACOM 2017 event in Cologne, Germany scheduled from May 30 - June 1, 2017.

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

The 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. While 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-EML transmitter operating at 1610 nm that supports a 5 - 85 MHz spectrum. It is also 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 can withstand a surge of 6 KV 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.
