Easy Lock is an SC type fiber adapter with the addition of a flexible retaining element on top of its surface edge. With this solution, unwanted disconnection of the standard SC connector is not possible, unless a tool or a particular release maneuver will be applied. This new adapter is mainly intended when optical fibers are handled by end users, but can be used also in situations where security problems are important (MDF in the central offices, closed-connect cabinets, termination boxes,...), as it guarantees compatibility with IEC 61754-4 SC connectors.
