Optical shuffle.

communication grade optical fiber is laid onto an adhesive substrate mate-
rial such as Kapton. Following the routing process, a thermoplastic material
is laminated over the optical circuit to encapsulate and protect the circuit
during handling and environmental extremes.
Another application for optical routing circuits is shown in Figures 5.45
and 5.46. In these cases the optical circuit provides interconnection of opto-
electronic components on a circuit card, such as optical transceivers and
