A resilient substrate structure, which can be rolled up around an axis, includes a substrate, a working patterned layer and a resilient structure. The substrate has a first surface and a second surface. The substrate is defined with a first edge and a second edge in a direction parallel to the axis. The working patterned layer is arranged on the substrate. The resilient structure is arranged on the second surface. The resilient structure includes a composite layer and a supporting layer, which keep attaching to each other. The composite layer has curve-able segments, each of which is parallel to the axis and connects to the first and second edges. The resilient structure is transformed to contain multiple wavy segments when the resilient substrate structure is at the retraction state. An electronic device including the resilient substrate structure and electronic elements is also disclosed.

An optical communication module is provided, including an input/output connector on one end through which a multi-signal including a video signal is input/output, an optical sub assembly (OSA) package on another end for converting the multi-signal into an optical signal, and a first connection end folded in a curved form so that a connection surface as one surface on which a first contact point is formed forms an outer circumference and a non-connection surface as another surface on which the first contact point is not formed forms an inner circumference to form upper and lower double-sided contacts with the input/output connector. The optical communication module may simplify a contact point structure with an input/output connector and reduce its manufacturing costs, by improving the contact point structure with an input/output connector, and may provide a high-speed transmission line having a relatively-low dielectric loss with respect to a video signal requiring high-speed transmission in synchronization with a high-speed clock signal and also have an improved structure favorable to mounting of an integrated circuit for signal processing with respect to an auxiliary signal or a peripheral circuit device connected to the integrated circuit.
