The present invention provides a bio-sheet material, and a method and an apparatus of manufacturing the bio-sheet, which has pliability or easiness of cutting by unifying a mixture of at least one of healthful natural minerals or plants such as ocher, jade, tourmalin, etc. The inner piece includes inner and outer surfaces, and a resin layer is integrally formed on the inner and outer surfaces of the inner piece by resin extending therebetween through the resin communication passage. The pin bores are adapted to receive centering pins that penetrate the connector body and facilitate connecting the connector body to a mating substrate one side and to mating optical fibers at the other side. Skew between clock and data signals, as well as among multiple data signals, can be reduced.
