Process Plug for FDDI Transceiver

       Disclosed is a Process Plug that protects the FDDI (Fiber
Distributed Data Interface) Transceiver optical ports from being
contaminated by process liquids and particulates. A cross-sectional
diagram of an FDDI Trancseiver plugged with a Process Plug is shown
in Fig. 1.

      The FDDI Process Plug is designed to seal off the FDDI
Transceiver optical ports. (See Fig. 1.) The SANTOPRENE* tips of the
Process Plug are compressed with a positive force of 8 to 22 lbs.
against the outside rim of the Transceiver's optical ports. Each
optical port contains delicate optics that are sensitive to
particulate contamina tion and liquid ingress. If the sensitive
optics within the optical port were to be contaminated, the optical
performance of the Transceiver's Average Optical Power and
Sensitivity parameters would be severely degraded.

      The FDDI Process Plug dimensions are dependant upon the FDDI
Transceiver port plug receptacle dimensions (Fig. 1 and 2). The
design allows for a Tranceiver tolerenced on the small side to
function properly with the Process Plug.

      The FDDI Process Plug allows for field installation of the
keying mechanism while the process plug is in place (Fig. 2). The
hole in the center of the plug allows for clearance of the keying
mechanism. The key itself is labeled "M" (Fig. 2) and serves as a
means of configuring the FDDI Transceiver into various fiber-optic
cabling schemes.
