Abstract: A configurable wavelength-selective cross-connect (WSXC) device having an array of optical ports in which at least some of the ports are configurable to operate as common ports or as plural ports. The configurable WSXC device includes a MEMS mirror array whose mirrors are tiltable in a manner that enables, e.g., reconfigurations of the configurable WSXC device that result in a change of the number of common ports therein. In one possible configuration, the configurable WSXC device can operate as 1×M1 wavelength-selective switch, where M1+1?P, and P is the total number of optical ports in the array of optical ports. In another possible configuration, the configurable WSXC device can operate as a bank of n 1×M2 wavelength-selective switches, where n is a positive integer greater than one, and n(M2+1)?P.

Abstract: An optical cross-connect switch having a fiber collimator array (FCA), a MEMS mirror array, and a folded 4F relay system. Each optical fiber in the FCA can work as an input fiber or an output fiber. The MEMS mirror array has individually tiltable mirrors, each mapped to a respective one of the optical fibers in the FCA. The folded 4F relay system is configured to image the FCA onto itself such that, for each input fiber, the tip of the fiber is imaged onto the tip of the intended output fiber. The MEMS mirror array can select the output fiber by (i) tilting the mirror mapped to the input fiber to cause light redirected by that mirror to impinge on the mirror mapped to the output fiber and (ii) tilting the mirror mapped to the output fiber to cause light redirected by that mirror to couple into the output fiber.

Abstract: A flexible cable is supported within the sealed disc drive housing, with one end of the cable readily, automatically soldered to the end wires of the spindle motor leads. The opposite or outboard end of the cable terminates in a header comprising a plastic mounting piece to support a multi-pin electrical connector with the pins extending from both sides of the header. Two locating pins are provided on the plastic header outside of a channel for defining the location of a gasket. The conductors in the cable terminate at four connecting pins at one end of the header. With the pins extending both above and below the header piece, immediately upon installation of the printed cable, the conductors to the spindle motor may be accessed so that the spindle motor and other elements of the head disc assembly may be tested during assembly of the complete disc drive.
