AI Technical Summary

Benefits of technology

The patent text describes a new design for optical connectors on circuit boards. The circuit board optical connector is securely attached to the edge of the circuit board, while the backplane optical connector can move around. Magnets are used to attract and hold the connectors together. This design allows for easier connection between circuit boards and makes the whole system more robust.

Problems solved by technology

As bandwidth demands increase there is an unresolved need to provide server blades or cards that can transmit high-speed optical signals.
Such optical connections may be costly due to the precise alignment requirements needed between the mated optical connectors.
In some cases, costly internal optical jumpers are required to facilitate board-side optical connections.
These internal optical jumpers not only add cost, but also introduce optical loss.

Embodiment Construction

[0037]Embodiments are directed to optical connectors and, more particularly, to backplane optical connectors and optical connections for edge-wise optical coupling of circuit boards to backplane structures. As an example and not a limitation, the backplane optical connectors and optical connections described herein may be employed in rack-based equipment, such as racks employed in data distribution centers and telecommunications applications. A floatable optical connector is employed on the backplane side, while a rigid optical connector is provided on the edge of the circuit board. Magnets are utilized to both provide the attractive force for initiating the float (i.e., movement) in the backplane optical connector as well as to maintain the mating force between the circuit board optical connector and the backplane optical connector. When the edge of the circuit board is brought into close proximity with the backplane, the backplane optical connector advances toward the circuit boar...

Abstract

Backplane optical connectors and optical connections are disclosed herein. In one embodiment, a backplane optical connector includes a ferrule element that includes a body portion having optical interface, at least two bores positioned through the body portion, at least two posts extending from the body portion, and a fiber inlet portion extending from the body portion. The fiber inlet portion includes a fiber receiving opening. The backplane optical connector further includes a magnet disposed within each bore of the at least two bores, and a bias member coupled to the at least two posts.

Description

PRIORITY APPLICATION[0001]This application is a divisional of U.S. patent application Ser. No. 14 / 950,465 filed on Nov. 24, 2015, the content of which is relied upon and incorporated herein by reference in its entirety, and the benefit of priority under 35 U.S.C. ยง 120 is hereby claimed.BACKGROUNDField[0002]The present disclosure generally relates to optical connectors and, more particularly, to optical connectors that optically couple components of a circuit board to a components of a backplane.Technical Background[0003]Benefits of devices having optical waveguides include extremely wide bandwidth and low noise operation. Because of these advantages, devices with optical waveguides are increasingly being used for a variety of applications, including but not limited to broadband voice, video, and data transmission. For example, fiber optic networks employing optical fiber are being developed and used to deliver voice, video, and data transmissions to subscribers over both private an...
