Abstract
A cap mountable over an optical port support and a securing member fixedly engagable through the cap to the optical port support. The seal also includes an indicator for indicating separation of the cap from the support. In one aspect, the cap has a base mountable over the support and a plate with a hook pivotally attached to the base. In another aspect, an extension projects from one portion of the cap and includes an aperture aligned with a threaded bore in the cap. An aperture in the shaft of the fastener is alignable with the aperture in the extension to receive a seal indicator. The fastener is provided with a hardened tip for secure engagement with the optical port support. In one aspect, the legs of the fastener are thin so as to be deformable upon the application of a predetermined amount of threading torque to the fastener. In another aspect, a tampering indicator is in the form of a tape applied over the optical port which permanently changes state when removed from the optical port to indicate tampering when reapplied to the optical port.
