The pre-assembled, one-piece body design and the pre-polished ferrules provide quick and economical terminations both in factory and in-the-field settings. Also, with the pre-polished ferrule and the Molex termination method, a uniform endface geometry is ensured, resulting in consistent optical performance. Connector mating is achieved by using bulkhead feed-through adapters. These adapters combine a metal housing and either a precision zirconia ceramic or a rugged phosphor bronze sleeve. Flange mount or "D" hole mount adapter styles are available. *NTT-FC is a trademark of NTT Advanced Technology Corporation
