MPO Trunk Cable-Its Polarity and Types

Today the use of MTP MPO Cables has increased tremendously. MTP trunk cable is often said an enhanced MPO cable version. MTP connector consists of a removable housing that permits polishing, re-working, and changing of connector heads. To make sure that the cable is not easily broken inside the connector housing it has a more advanced mechanical support system.

However, there are many MPO who from the extensive bending force has implemented the same type of mechanical support and provide breaking resistance, but it never guarantees a removable housing.

MPO trunk cable /MTP technology has some properties like high density, flexibility, and reliability with scalable, upgradeable properties. It ensures that to receive the port of the second piece of active equipment, a transmit signal from any type of active equipment will be directed across a fiber network if the right polarity is maintained.

Three Types of Cables for Three Polarization Methods

MPO Trunk Cable Type A: Type A cable also referred to as straight cable consists of a key up MPO connector on one end and the opposite end a key down MPO connector. The same fiber position can be maintained through these fibers at each end of the cable.

MPO Trunk Cable Type B: On both ends of the cable Type B cable make use of a key-up connector. Inversion happens through his type of array mating, which indicates that at each end the fiber positions are reversed.

MPO Trunk Cable Type C: Having one key up and one key down connector on every side, the Type C cable looks similar to Type-A cable. But, in Type C at one end each adjacent pair of fibers are flipped at the other end.

Conclusion

Network designers make use of MPO/ MTP trunk cable components so that they can satisfy the increasing requirement for higher transmission speed. By doing this one of the big issues that are polarity is solved. MTP connector consists of a removable housing that permits polishing, re-working, and changing of connector heads. However, it also needs a selection of the right types of MPO cassette, MPO cables, MPO connectors, and patch cables.
