Abstract:
A holding device for dense wavelength division multiplexers, the holding device comprising:a base; a plurality of projections extending upwardly from the base; a plurality of grooves defined between the projections; and a plurality of sleeves; wherein each of said sleeves enclosing a dense wavelength division multiplexer is fittingly received in the corresponding groove, each of the sleeves being clamped by two corresponding adjacent projections; wherein each of the grooves has a generally C-shaped profile; wherein each of said projections defines a C-shaped slot in an upper portion thereof for retaining an optical fiber therein; wherein the holding device is made of elastic material; wherein â€ƒeach of the grooves comprises a portion having a generally circular profile, and a diameter of the circular profile is substantially equal to a diameter of a corresponding sleeve; wherein â€ƒa width of a top portion of each of the grooves is less than the diameter of the circular profile of the groove; wherein â€ƒthe upper portion of each of the projections forms two chamfers on opposite sides of a corresponding slot, and the chamfers extend upwardly in a diverging manner; wherein â€ƒan upper portion of each of the projections forms two slanted faces on opposite sides thereof, and the two slanted faces of any two projections that oppose each other across an intervening groove extend upwardly in a diverging manner, the holding device further comprising a C-shaped bead formed in each of the grooves; and wherein each of the sleeves defines a circumferential recess therein for fittingly receiving a corresponding bead of the holding device.
