Abstract: A multiple fiber push-on (MPO) optical connector is provided having a ferrule configured to house multiple optical fibers and including a stepped portion extending from at least one pair of opposing exterior surfaces of the ferrule. A one-piece housing-backpost is provided having a distal end in a connection direction and a proximal end in a cable direction. The one-piece housing-backpost is configured to receive a ferrule spring and the ferrule from the distal end. The housing-backpost includes at least one resiliently-deformable ferrule-retaining protrusion extending from a sidewall to engage a corresponding stepped portion of the ferrule. The resiliently-deformable ferrule-retaining protrusion is configured to deform towards the housing-backpost interior sidewall as the ferrule is inserted from the distal end and to extend outward against the stepped portion of the ferrule when the ferrule is seated in the housing-backpost to maintain the ferrule in the housing-backpost.

Abstract: An optical connector is provided having a ferrule configured to house one or more optical fibers. An inner housing is provided to hold the ferrule and has a distal end in a connection direction and a proximal end in a cable direction. An outer housing at least partially surrounds the inner housing. One or more resilient forward biasing projections extend from one or more of the outer housing or the inner housing for biasing the outer housing towards the distal end of the inner housing. The resilient forward biasing projection may be integrally formed with either the inner housing or with the outer housing.
