Abstract
Cross-compatible VSFF connection systems include optical connectors that are compatible with at least two types of adapters and adapters that are compatible with at least two types of optical connectors. Optical connectors have one or both of connector latch recesses and depressible latches, and likewise adapters have one or both of adapter latch arms and adapter latch recesses. Dual latch function connectors and adapters are capable of connection to a mating components that have only one type of latch structure, e.g., only recesses or only latches. Connection systems can be duplex or MT and may facilitate push-pull boot remote release and polarity change.
Claims19
A VSFF optical fiber connector comprising:
- a connector housing having a top portion and a bottom portion;
- a ferrule arrangement for terminating a plurality of optical fibers, the ferrule arrangement comprising one of (i) a pair of spring-loaded single-fiber ferrules and (ii) a single spring-loaded MT ferrule, the ferrule arrangement being received in the connector housing such that the optical fibers are spaced apart vertically between the top portion and the bottom portion of the connector housing;
- a connector latch recess configured for latching with an adapter latch arm of a mating adapter of a first type;
- and
- a connector latch configured for latching with an adapter latch recess of a mating adapter of a second type.
