Data center infrastructure maintenance
When it may not be suitable
This coupler is designed specifically for SC duplex multimode connections and is not compatible with single-mode fibre cables or different connector types such as LC or ST. It should not be used in environments where high-vibration or extreme mechanical stress is present without additional cable management support.
