Optically connecting two transceivers requires the transmitting portion of one transceiver matches with the receiving portion of the other transceivers. This requires that the polarity of the fiber optic connectors (attached to one another in a jumper) that connect the two transceivers is correct. Maintaining the correct polarity in the field can be confusing, time-consuming, and difficult to achieve. Not to mention that the installers need to make sure they have the correct number and polarity of the jumpers. This is further complicated when the fiber optic connectors are VSFF and have a key on a short side of the fiber optic connector. A system that involves an A-to-B patch cord and an opposed key adapter solves each of these issues. Only one type of patch cord (A-to-B) and one type of adapter is needed. With these components, an installer can connect the two transceivers without any mistakes.

Polarity scheme for multi-fiber connectors with a connector key

A fiber optic connector has at least two optical fibers therein have end faces that are positioned such that they are directed in different directions. The end faces can be oriented relative to a key that is provided on a fiber optic connector housing that has a central opening in the main body of the fiber optic connector.
