Expanded beam connectors can reduce the impact of contamination on connector loss compared to fiber-based physical contact connectors due to the increased lens surface area compared to the fiber core. However, the technology does not completely eliminate these additional losses. To date, no formal inspection criteria for allowed lens defects, including contamination, have been adopted by the industry for any expanded beam connectors.
Phases 1 and 2 of iNEMI’s Development of Cleanliness Specification for Expanded Beam Connectors project developed a unique approach for visual inspection criteria for cleanliness on multimode expanded beam connectors. iNEMI is now organizing a third phase to develop visual inspection criteria for single-mode expanded beam connectors.
In line with this, iNEMI is inviting the industry to join the call-for-participation webinar to review plans and objectives for Phase 3 of this important project. Two webinar sessions are scheduled, and are open to members and non-members:
