Optical connector assemblies, optical receptacle assemblies and optical connection systems having multiple optical fibers

An optical connection system comprising:

• an optical receptacle assembly comprising:
• a receptacle housing, wherein the receptacle housing defines a receptacle passage;
• an adapter sleeve disposed within the receptacle passage of the receptacle housing, the adapter sleeve comprising a sleeve passage and a sleeve inner threaded surface;
• an adapter housing disposed within the receptacle passage, the adapter housing comprising a first connector opening and a second connector opening;
• and
• a first receptacle optical connector and a second receptacle optical connector, wherein the first receptacle optical connector is disposed within the first connector opening of the adapter housing and the second receptacle optical connector is disposed within the second connector opening of the adapter housing;
• an optical plug connector assembly comprising:
• a shroud defining a shroud passage and comprising an outer coupling surface;
• a coupling nut comprising a threaded outer surface and a coupling nut passage, wherein:
• the outer coupling surface of the shroud is disposed within the coupling nut passage such that the coupling nut is configured to rotate about the outer coupling surface of the shroud;
• and
• the threaded outer surface of the coupling nut is configured to threadably engage the sleeve inner threaded surface of the adapter sleeve;
• a connector housing comprising a first plug connector opening and a second plug connector opening, wherein the connector housing is disposed within the shroud passage;
• and
• a first plug optical connector and a second plug optical connector, wherein the first plug optical connector is disposed within the first plug connector opening and the second plug optical connector is disposed within the second plug connector opening.

An optical connector assembly comprising:

• a connector housing, wherein the connector housing defines a passage and an opening;
• an adapter housing disposed within the passage, the adapter housing comprising a first connector opening and a second connector opening, and wherein the adapter housing comprises a pair of opposing central protruding portions each operable to receive an optical connector;
• at least one bias member disposed between at least one tab of the adapter housing and a surface of the connector housing such that the at least one bias member biases the adapter housing within the connector housing forward toward the opening of the connector housing and enables the adapter housing to translate back away from the opening of the connector housing during connector mating;
• and
• a first cable optical connector and a second cable optical connector, wherein the first cable optical connector is disposed within the first connector opening of the adapter housing and the second cable optical connector is disposed within the second connector opening of the adapter housing.
