MPO connector is also called MTP

MPO connectors are also known as MTP® connectors, with MTP® being a high-performance, branded variant of MPO.

MP

O stands for Multi-Fiber Push-On, a standardized multi-fiber connector designed to terminate multiple optical fibers (commonly 12, 16, or 24) in a single ferrule, enabling high-density fiber optic connections in data centers and telecommunications networks. MTP® stands for Multi-Fiber Termination Push-On, a registered trademark of US Conec, and represents an enhanced version of the MPO connector with improved mechanical and optical performance. Both connectors are compatible and often used interchangeably, but MTP® includes design improvements such as floating ferrules, metal pin clamps, and removable housings for better durability and alignment.

Key Features and Differences

Ferrule Design: MPO connectors have a fixed ferrule, while MTP® connectors use a floating ferrule to maintain optimal fiber contact under mechanical stress. Pin Clamps: MPO connectors use plastic pin clamps, whereas MTP® connectors employ metal pin clamps for enhanced reliability. Guide Pins: MPO connectors have chamfered guide pins, while MTP® connectors feature elliptically shaped stainless-steel guide pins for better alignment and reduced wear.

Applications: Both are used for single-mode and multi-mode ribbon cables, supporting high-speed data transmission (40G, 100G, 400G) in high-density network environments.

Summary

In essence, MPO and MTP® connectors refer to the same type of multi-fiber connector, with MTP® being a branded, performance-enhanced version of MPO. They are widely used in modern data centers for their high-density, high-speed, and reliable fiber optic connections.
