First Claim
1. An adapter for holding first and second fiber optic connectors in coaxial alignment, the first connector having a first connector portion, the second connector having a second connector portion different from the first connector portion, the adapter comprising:
- a main body having an axial cavity extending between first and second ends, the main body having a side opening, the axial cavity defining first and second grooves extending transversely to the axial direction and communicating with the side opening;
a cover closing the side opening; and
an inner housing disposed within the main body, the inner housing including;
a first mating portion defining an SC mating portion positioned at the first end of the main body, the SC mating portion including a first cylindrical portion and a retaining clip, the first cylindrical portion and the retaining clip extending in the axial direction, the SC mating portion further including a first flange received by the first groove; and
a second mating portion positioned at the second end of the main body, the second portion including a different adapter configuration from the SC mating portion, the second mating portion including a second flange received by the second groove.

Abstract
A hybrid adapter permits connection of one type of connector, such as an SC-type, with a different type, such as an ST-type connector. An alternative adapter permits connection between an SC-type connector and an FC-type connector. A main body which holds the connectors in axial alignment includes a side opening. An inner housing is configured for mating with the different type connectors. The inner housing is inserted through the side opening, which is closed off by a cover. Various parts of the adapter are common between the two disclosed style adapters.
