MPO is the industry acronym for “multi-fiber push on”MPO fiber optic connector is a multi-core and multi-channel plug-in connector. Interface connectors are used to connect pluggable modules and the corresponding transmission media. Optical fiber connector is an 
indispensable passive device in the optical fiber communication system.
The MPO-style connectors are most commonly defined by two different documents from IEC and EIA, respectively are IEC-61754-7 is the commonly sited standard for MPO connectors internationally and EIA/TIA-604-5, also known as FOCIS 5.
It makes possible to disassemble the connection between optical channels, which not only facilitates the measurement and maintenance of optical system, but also makes the switching scheduling of optical system more flexible.
Structure of MPO Optical Fiber Connector:
It is used for the Compact design of MPO Connector are available to 4, 8, 12, 24 ribbon fiber cable. The pre-terminated MPO Connector save time and reduce the risk of damage fragile optical connectors.
At most, two rows of 24 core optical fibers can be connected at the same time. According to IEC 61754-7, the types of MPO fiber optic connectors are distinguished by several factors: number of cores, male and female heads, polarity, and polishing type.
MPO fiber connection principles:
- must be the same core number connector connection;
- A male head and a female head are joined in a pair;
- Must be connected for the same polishing type;
- The polarity of the MPO fiber connection is managed by Key, and two keys are defined: up and down;
- A pair of MPO fiber connections is matched by an MPO fiber adapter, which comes in two types: class A defined up-down and class B defined up-up.Fiber polarity can be managed by selecting class A or class B adapters;
- Fibre optic connection with APC junction surface of MPO cant exist 8 °, only through A class A adapter to docking.
Advantages of MPO Connectors:
- Designed for low loss and standard loss SM and MM applications;
- High precision, precise MT guide pin and guide hole ensure the accuracy of optical fiber docking;
- With high density and precise geometric design, it can support the application of 12-72 or even 96-core fiber.
Application of MPO Connector:
- The application of data center in high density environment;
- The application of optical fiber to the home and building;
- Internal Connection Applications of Spectrometer, 40G/100GSFP, SF+Optical Module.
The optical cable connected with MPO connector at both ends is MPO optical fiber jumper. Because of the compact structure design of MPO connector, MPO optical fiber jumper has the characteristics of many cores and small volume.
