In an optical receiver, a light receiving element receives the optical packet signals and converts the optical packet signals to electrical signals. This invention provides a wobble signal processing apparatus that can reduce the circuit scale and the power consumption as well as improve the quality of signal processing. The method further includes the steps of progressively closing the die halves to progressively deform the tubular member and progressively expel the at least one portion of the tubular member to define a flange comprised of wall portions of the tubular member engaging one another. The connector set sendsreceives data tofrom network resources through a communication device.
