Abstract

A signal-carrying laser beam is deflected 45 degrees, offset laterally, and deflected 45 degrees again to wrap the beam back to the receiver which is in a plane parallel to the transmitter. This is done for the purposes of diagnosing both the transmitter and the receiver on the same card simultaneously. In addition, in the absence of a fiber-optic connector, the transmitted laser beam is diverted in a safe direction, thereby providing protection against beam exposure to the human eye.

Integral Shell Mounted Wrapshield

      A signal-carrying laser beam is deflected 45 degrees, offset
laterally, and deflected 45 degrees again to wrap the beam back to
the receiver which is in a plane parallel to the transmitter.  This
is done for the purposes of diagnosing both the transmitter and the
receiver on the same card simultaneously.  In addition, in the
absence of a fiber-optic connector, the transmitted laser beam is
diverted in a safe direction, thereby providing protection against
beam exposure to the human eye.

      Both flexible arms are an integral part of the alignment shell.
They deflect away upon entry of a fiber-optic connector.  When the
connector is withdrawn the arms return to the original position and
provide the previous wrap and safety functions.
