Abstract

Systems and methods can operate to detect and avoid optical beat interference (OBI) in broadband devices by use of restrictive channel assignment. An OBI-mitigating mapper algorithm can leash OBI candidates in a circular queue to avoid scheduling service flows likely to result in OBI generation. In some implementations, the algorithm can automatically leash all pre-DOCSIS 3.0 service flows. In alternative implementations, the algorithm can allow the CMTS to normally load balance pre-DOCSIS 3.0 devices while manually adding and/or removing pre-DOCSIS 3.0 service flows from the OBI candidate queue based upon lost transmissions or a designated age-out timer.
