Abstract

A card for optical driver and receiver modules is attached at one edge to a metal channel stiffener, and the stiffener extends sufficiently beyond the card edges to provide points for attaching the stiffener to a supporting structure in an enclosure for the apparatus. A driver module and a receiver module are each mechanically connected to the stiffener and are electrically connected to conductors on the card. Each module has a socket for receiving a ferrule that holds the end of an optical fiber, and pairs of modules are positioned on the card and stiffener with a standard spacing between the ferrule sockets. A connector housing mechanically supports the ferrules with a spring loading that permits the end of a ferrule to abut the light sensing or light emitting components in the modules.

Combined Sending and Receiving Circuit Modules and Connector for Two Fiber Cables

      A card for optical driver and receiver modules is attached at
one edge to a metal channel stiffener, and the stiffener extends
sufficiently beyond the card edges to provide points for attaching
the stiffener to a supporting structure in an enclosure for the
apparatus.  A driver module and a receiver module are each
mechanically connected to the stiffener and are electrically
connected to conductors on the card.  Each module has a socket for
receiving a ferrule that holds the end of an optical fiber, and pairs
of modules are positioned on the card and stiffener with a standard
spacing between the ferrule sockets.  A connector housing
mechanically supports the ferrules with a spring loading that permits
the end of a ferrule to abut the light sensing or light emitting
components in the modules.  Each module has a locating pin that is
positioned so that for a pair of modules the locating pins are
outside the two ferrule receiving sockets and are coplanar with them.
The connector housing has correspondingly positioned locating
receivers.  Thus, the mechanical force of plugging in and unplugging
a connector is carried by the locating pins and by the stiffener and
not by the card or the module or the optical fiber cables.  The pins
have a circumferential groove near their outer ends, and a spring
clip carried by the connector housing is manually movable between
positions to lock and r...
