MPO/MTO Series Connectors
MPO/MTO Series Connectors
*Inserts and Fixtures Designed and Manufactured by Kyomori-Ka
At the core of the MTO is the MT ferrule independently developed by Jingsen Hong; the integrated design of the device and termination process ensures high yields and reliable field assembly.
*Precision Components that Exceed Standard Requirements
MTO series connectors utilize rigorous tolerance control to achieve superior optical performance, while a dust-resistant design ensures high stability and repeatability.
*The New Functional Design Ensures Reliability and Availability
An elliptical guide pin enhances durability and simplifies installation, while a floating ferrule pre-alignment design ensures a secure connection. A detachable housing facilitates maintenance;
an elliptical spring optimizes the clearance between dimensions and the fiber, and a centering structure guarantees consistent, stable performance.
