Overview of MPO Connectors and MTP Variants

What are MPO Connectors?

MPO connectors are fiber optic connectors with multi fiber connectivity and a push on coupling, that’s why they are called MPO “multi-fiber push on”. MPO connectors support higher bandwidth and higher density applications with 12 to 24 fiber count, which also can reach 48 or 72 in some limited applications.

Male and Female MPO/MTP Connectors

In addition, the next MPO format will support 16 to 32 fiber connectors, which are required for 400 GB applications. There two versions of MPO: male (with pins) and female (without pins).

What is the difference between MPO and MTP?

  • MTP connectors are high performance MPO connectors designed for better mechanical and optical performance.
  • With removable housing feature, MTP connectors allow changing, re-polishing or interferometrically scanning the MT ferrule or even changing the gender of the connector after assembly or in the field.
  • An MTP connector has a floating ferrule, which improves mechanical performance. This means that two mated ferrules can maintain physical contact while under load.
  • MPO connectors have plastic pin clamp and round spring, but MTP connectors have metal pin clamp and round spring.
  • Furthermore, having a metal pin clamp allows the push spring on the MTP connector to always stay centered. This feature prevents losing pins, centralizes the spring and protects it from any potential damage.
  • The guide hole wear in MPO connectors may appear after about 50 parings. However, with MTP connectors, that range is improved to 500 pairings.

MPO Connectors Advantages and Disadvantages?

The rapid increase in the number of network links in the data centers can cause the data center of conventional fiber cabling to become cramped and difficult to manage. To solve this problem, data centers must obtain ultra-density to accommodate all the cabling used in the cabling.

MPO Connector Advantages:

MPO/MTP cables, which combine 8, 12 or 24 fibers in a single interface, have proven to be a practical solution for that problem. In addition, the MTP/MPO multi-fiber cable connectors can accommodate 8, 12 or 24 fiber in the same area needed for an SC connector, meeting the 40GBASE-SR4 and 100GBASE-SR10 standards, and eventually, MPO connectors can effectively save card and rack space.

MPO Connector Disadvantage:

An MPO/MTP connector has a very sensitive surface that cannot be cleaned easily.

How Are MPO Cables Connected?

To establish an MPO connection between two MPO cables, an MPO adapter is a must and the connectors should have opposing types. Which means only male to female connection is possible, not male-male or female-female. If a female connector is used on both sides of the adapter the performance would be very low because without male pins the fibers would not be aligned. On the other hand using two male connectors is not possible and might damage the connectors.

How to Measure the Quality of MPO cables?

  • After MPO cables are produced, they get cleaned and assessed both microscopically and geometrically to ensure they are clean and with high quality.
  • A VIAVI MPO test device is used to measure light transmittance and make sure the fiber connectors are providing standard values. In order to do the measurement.
  • We need 1 jumper cable fixed to the device, 1 master cable determined by the type of cable we seek to measure and the actual measured DUT cable.
  • The cables must be clean before the measurement and with the master cable in mind.
  • Afterwards, the measured cable is connected to master cable and the device in order to be tested, and a precise reading with the final measurement result is given by the device.
