January 17, 2013 – Exfo Inc. says it has signed a partnership agreement with Sumitomo Electric Industries (SEI) whereby its recently launched FG-750 Node iOLM (an OTDR-based remote test unit for automated FTTH fault management) is now fully qualified with Sumitomo’s reflective termination filter technology. Through this partnership, both companies will leverage their respective FTTH test and diagnosis expertise in advanced optical-line testing and monitoring applications. The FG-750 Node iOLM is a fixed remote test unit that performs in-service, end-to-end testing, monitoring and troubleshooting of PON topologies from the central office. It can test point-to-multipoint fibers, or run downstream tests from the node or central office to any passive optical network line type.
