Abstract
Abstract A digital inter and intra printed circuit board communication system wherein high speed data transfers occur using fiber optics signals. Ease of connection of the fiber optics wave-guides is facilitated through the use of wave-guides embedded with the circuit board and through the use of fiber optics edge connectors.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
117 words
An apparatus providing communication resources within a substrate assembly, the apparatus having: A) a substrate; B) a first set of at least one optical wave-guide embedded within the substrate with an optical connection at a first end of a wave-guide between the wave-guide and at least one electro-optical component mounted on such substrate; and C) at least one connector containing a means for connecting and automatically aligning a second end of the at least one wave-guide within the substrate with an at least one wave-guide external to the substrate to form a resultant optical connection with such resultant optical connection used for at least one-way transmission of an optical signal between the substrate and other, external, devices.
Claim 2
Independent Claim
117 words
An apparatus providing communication resources within a substrate assembly, the apparatus having: A) a substrate; B) a first set of at least one optical wave-guide embedded within the substrate with an optical connection at a first end of a wave-guide between the wave-guide and at least one electro-optical component mounted on such substrate; and C) at least one connector containing a means for connecting and automatically aligning a second end of the at least one wave-guide within the substrate with an at least one wave-guide external to the substrate to form a resultant optical connection with such resultant optical connection used for at least one-way transmission of an optical signal between the substrate and other, external, devices.
Claim 3
Dependent Claim
66 words
The apparatus in claim 1 wherein a second set of at least one optical wave-guide is embedded within the substrate at substantially right angles to the first set and interconnected to the first set through the use of optical taps such that a portion of the optical signal transmitted through a wave-guide in the first set is also transmitted through a wave-guide in the second set.
Claim 4
Dependent Claim
39 words
The apparatus of claim 1 wherein the optical signal within a wave-guide are selectively switched, conditioned , and, upon occasion re-transmitted within the same, or upon occasion, another wave-guide through the operation of optical components mounted on the substrate.
Claim 5
Dependent Claim
34 words
The apparatus of claim 1 wherein optical impulses within a wave-guide are selectively switchable by operation of an optical switch from the wave-guide and transmitted for consumption, or use, within at least one component.
Claim 6
Dependent Claim
20 words
The apparatus of claim 1 wherein optical signals enters and, upon occasion, leave the substrate assembly through a surface plane.
Claim 7
Dependent Claim
15 words
The apparatus of claim 1 wherein the substrate assembly contains at least one electro-optical device.
Claim 8
Independent Claim
151 words
A method of providing communication resources within a substrate assembly having: A) a substrate; B) a first set of at least one optical wave-guide embedded within the substrate with an optical connection at a first end of a wave-guide between the wave-guide and at least one optical component mounted on the substrate; and C) at least one connector containing a means for connecting and automatically aligning a second end of the at least one wave-guide within the substrate with an at least one wave-guide external to the substrate with such resultant optical connection used for at least one-way transmission of data between the substrate and other, external, devices. the method comprising the steps of: A) interconnecting at least one optical transducer to the wave-guide embedded within the substrate; and B) transmitting at least a one-way optical signal between external optical devices for use or re-transmission within devices located on the substrate.
Claim 9
Independent Claim
