What is MPO connectors: structure and function
The MPO connector (known as multi-fiber push-on and also as multi-path push-on) is a multi-fiber connector defined according to IEC 61754-7 and TIA/EIA 604-5 that can accommodate up to 72 fibers in the tiniest of spaces, comparable to an RJ45 connector. MPO connectors are most commonly used for 12 or 24 fibers
What is MTP Connectors
The MTP connector is a high-performance MPO connector with multiple engineered product enhancements to improve optical and mechanical performance when compared to generic MPO connectors.
The MTP connector is in complete compliance with all MPO connector standards including the EIA/TIA-604-5 FOCIS 5 and the IEC-61754-7. The MTP connector is inter-matable with all generic MPO-style connectors that are compliant to these industry standards. Generic MPO connectors are limited in performance and are not able to offer the high-performance levels of the US Conec MTP connector.
Difference between MPO Connectors and MTP Connectors?
From the outside, there is very little noticeable difference between MPO and MTP connectors. In fact, they are completely compatible and inter-mateable. For example, an MTP trunk cable can plug into an MPO outlet and vice versa.
The main difference is in relation to its optical and mechanical performance. MTP is a registered trademark and design of UsConnec and provides some advantages over a generic MPO connector. Since MPO / MTP optic fibre alignment is critical to ensure a precise connection there are some benefits in utilizing the MTP connector. The MTP connector is a high-performance MPO connector with multiple engineered product enhancements to improve optical and mechanical performance when compared to generic MPO connectors.
The MTP optic fibre connector has a floating internal ferrule which allows two mated ferrules to maintain contact while under load. In addition, The MTP connector spring design maximizes ribbon clearance for twelve fibre and multifibre ribbon applications to prevent fibre damage.
Overall it provides a more reliable and precise connection. In addition, it is also important when specifying an MPO/MTP system to ensure the correct polarity options and which cables and outlets have female or male pins.
