Generic-Mode Fiber-Optic Wrap Plug

      Disclosed is a fiber-optic wrap plug device that functions for
both single-mode and multi-mode fiber-optic transmission.

      The wrap plug is a device that mechanically connects to an
opto-electronic transceiver and optically couples a transmitter and
receiver through a short piece of optically-transmitting fiber.  The
wrap plug attenuates the light traveling from transmitter to
receiver.  Attenuation is achieved by connection loss at the
transmitter/fiber and receiver/fiber interfaces, and transmission
loss in the fiber.

      The wrap plug device is composed of a cable assembly and
housing.  The cable assembly consists of a light-transmitting fiber,
ferrules, and springs.  The fiber is a large-diameter plastic coated
with layers of polymer to protect it from handling damage.
Properties of the core are selected to provide a desired level of
optical transmission loss.  The fiber core has a larger diameter than
typical single-mode and multi-mode optically-transmitting fibers for
data transmission.  Typically, wrap plug core sizes are, but not
limited to, 200, 250 and 500 micrometers.  The large core enables
either multi-mode or single-mode optical transmission from a
transmitter through the fiber to a receiver.  The fiber is terminated
in a ferrule by fixing the fiber in a ferrule's hollow core,
typically by epoxy.  Ferrule surfaces are finished to provide a
flush, but not necessarily flat, ferrule-fiber endfa...
