Fiber Distributed Data Interface Network Keys for IBM FTM-1 Module

                    FIG. 1

      Four (4) module connector interface keys are defined by ANSI
for FDDI Optical Networks.  Disclosed is a key design that is a
non-permanent module feature, yet is reliable, and easily assembled
to the IBM FDDI module (FTM-1) at the discretion of the customer.

      Fig. 1 illustrates the Key Assembly which contains the MIC A,
MIC B, MIC M and MIC S keys as specified by ANSI(#3T9.5/84-48).  Fig.
2 illustrates how any one of the keys are assembled (snapped) onto
the front of the FTM-1 module.  Flaps (1) and (2) open away from the
key support (3) as it slides onto the front of module feature (4),
allowing the key support (3) to snap into the window (5), locking it
securely into place.  Once assembled into place, the key is designed
so that it cannot be dislodged by the connector, yet the key can be
manipulated by the customer and removed if it becomes necessary to
change the module key designation.

                    FIG. 2

      The assembly of the keys to the module requires no special
tooling as compared to competitor designs.  The keys are made of a
filled plastic for wear resistance, and include specifically placed
chamfers to facilitate assembly and to protect against mis-plugging
events by the connector.
