OBI-Free

When two upstream optical transmitters with the same wavelength transmit at the same time, and if their wavelengths are close enough, Optical Beat Interference (OBI) occurs. This is commonly found in traditional RFoG (RF over glass) architectures.

Lindsay Broadband offers a number of different technologies to mitigate and eliminate OBI in an RFoG architecture. This allows operators to deploy high capacity in DOCSIS® 3.0 and 3.1 FTTH (Fiber to the Home) networks. Products include our NoBI® outside plant (OSP) OBI eliminating active optical splitters, to subscriber wavelength-selectable OBI-free RFoG ONUs (optical network units).
