MPO Keyed Adapter

The MPO Key adapter is a specially designed optical fiber adapter. Through the Key (keyway) structure, it ensures that the MPO connector can only be inserted in a specific direction, preventing polarity errors or misinsertion. It is mainly used in high-density optical fiber cabling systems (such as 40G/100G networks in data centers).
