The SM E2000 fiber patch cord use a 1.25mm ceramic (zirconia) ferrule.
E2000’s are small form factor connectors with a moulding plastic body similar to that of an LC.
The E2000 also exhibits a push-pull latching mechanism, and integrates a protective cap over the ferrule, which acts as a dust shield and shields users from laser emissions.
The protective cap is loaded with an integrated spring to ensure proper closing of the cap.Like other small form factor connectors, the E-2000 connector is suited for high-density.
