Abstract

Cost effective implementation of byte-wide optical interconnects requires inexpensive packaging which will provide adequate alignment and pluggability. Conventional fiber connectors are too bulky to be considered for use in these highly parallel interconnects, and a recent patent (*) deals with a method for easing alignment tolerances required for the implementation of these links.

Integrated Electro-optical Connector

       Cost effective implementation of byte-wide optical
interconnects requires inexpensive packaging which will provide
adequate alignment and pluggability.  Conventional fiber connectors
are too bulky to be considered for use in these highly parallel
interconnects, and a recent patent (*) deals with a method for easing
alignment tolerances required for the implementation of these links.

      We disclose a connector structure comprising multiple
electrical and optical interconnect lines in a single low-cost
moulded plastic housing.  Though the concept of an optical imaging
connector is already patented (*), this disclosure provides an
inexpensive structure which integrates optical and electrical
interconnection functions in one structure.  An additional new
feature of the disclosure is the use of the electrical
interconnection pins for alignment of the optical elements.

      Electrical pins are moulded into a plastic housing into which a
fused fiber plate (see (*)) is mounted.  The pins in this assembly
provide alignment to the  optical  elements on the card below.  A
second plastic structure is fabricated using the same mould, but with
electrical pins chosen to mate with those in the first half of the
connector.  Instead of a fiber plate, a flexible fiber ribbon is
inserted into the central cavity of the moulded connector with
suitable plastic spacers (which can also be moulded).

      Since the mould fix...
