Fiber-Optic Connector Interface Scheme that Provides for Worldwide
Class 1 Laser Certification

      Disclosed is a simple, low cost, effective laser safety class
one transceiver connector interface.  The connector interface
features an easy to assemble spring/shutter design.

The disclosed connector interface assembly contains five pieces
(three part numbers).

1.  The Connector Housing.  A rigid piece of plastic material.
    Allows a full 360-degree encasement around the fiber-optic
    connector.  The housing's rigidity limits the effect any dynamic
    stimulus applied to the connector from effecting the fiber-optic
    connection.  It has provisions for two shutter and spring
    assemblies to be easily inserted and retained.  When assembled,
    the housing allows for pivoting of the shutter/spring assembly
    upon connector insertion.

2.  The Shutter.  Also made from plastic, actually blocks the laser
    radiation when a connector is not present.  When assembled with a
    spring into the connector housing, it is forced down toward the
    bottom side of the connector housing, thereby blocking any laser
    radiation.  The spring's design is to provide for 100% blockage
    of the laser radiation, yet not interfere or "jam" the
    fiber-optic connector insertion.  While a connector is plugged
    into the connector module, the shutter is retained (stored) in a
    storage provision in the connector housing...
