As a part of our huge fiber collection, we’ve got a fast one: the distinction between MPO/MTP female and male connectors. It will finally lead right into a polarity dialogue, however we’re setting a basis right here. Allow us to get into the connector variations.
Distinction Between MPO/MTP Male and Feminine Connectors
Attending to it, the important thing distinction between the female and male model of the connectors is the presence of pins. One can see the feminine connector on the left and the male connector on the proper under.
The 2 steel pins are the information pins that assist guarantee correct mating. These pins are literally designed merely for alignment functions and will not be carrying any optical alerts over them.
For these questioning, the remainder of the connector meeting is normally the identical, it’s simply the addition of pins that modifications the connector’s gender. It’s normally potential to alter the gender of a cable, and there are MTP Professional cables which have a reasonably straightforward discipline instrument to do the substitute with out having to undergo the method of opening the connector.
When it comes to set up, technically one can put a feminine to feminine connector in a coupling system. Normally this results in poor alignment of the fiber strands (the 12 fibers between the 2 pins.) Utilizing two male connectors could cause injury as a result of these are steel pins so it’s all the time beneficial to keep away from that setup to not injury the fiber. Additionally, as a result of the pins ought to contact one another, it’s going to imply the fiber strands will not be aligned and thus you’re unlikely to make an information connection over that mating try.
This can be a small matter, however an necessary one many which might be new to MPO/ MTP cables usually miss. Each connectors are very comparable so the massive distinction is admittedly simply the presence of pins.
On optical transceivers, the connectors are nearly all the time pinned. Because of this, one would wish to put a feminine connector into optical transceivers to keep away from injury.

We now have a polarity information coming as properly.
