MPO Guide Pins

Guide pins are used to guide and align MPO optical fiber connectors to ensure precise connection. Designing pin needles requires ultra-high precision to allow a proper connection. Based on the accuracy of the guide pins there are three main categories available.

The first category is MM or multi-mode. The second one is SM or single-mode. Finally, there are low loss guide pins that require the highest precision. The quality of the guide pins will directly affect the insertion loss value of the MPO connector.
