Abstract
A connector system for fiber optic cables employs an interface module located between the cable connector and the system component receiving the optical signals that converts the single-mode light on the cable to a mixture of modes that fill a multi-mode waveguide on the system board, thereby reducing modal noise and differential mode delay. A particular connector produces an electrical signal reflecting whether the optical connection is within specifications.
Claims15
An optical interface module for coupling optical radiation between a connector containing at least two optical fibers and at least two corresponding optical transmitting members in a system module comprising:
- a first interface coupled to said connector;
- and
- a second interface coupled to said at least two corresponding optical transmitting members;
- in which at least one of said first and second interfaces includes a mode transforming unit adapted for coupling radiation between different modes.
An optical interface module for coupling optical radiation between a connector containing at least two optical fibers and at least two corresponding optical transmitting members in a system module comprising:
- a first interface coupled to said connector in which said connector has a set of corresponding conductors associated with each fiber that produce an electrical effect when said connectors are properly engaged.
