Patent number: 7056156Abstract: The present invention relates to an electronic module, such as an opto-electronic transceiver or a copper transceiver, for plugging into a host receptacle. In an effort to eliminate the use of costly and inefficient sheet metal spring fingers for reducing EMI emissions, the present invention proposes to use solid conductive projections extending outwardly from the sides and top of the module housing. However, in highly populated host receptacles, adjacent cages often share a common sheet metal wall, which will deform when a module with a solid projection extending therefrom is inserted, thereby making insertion of an adjacent module very difficult. The present invention eliminates this problem by vertically offsetting projections on the opposite sides of the housing so no two projections are in the same horizontal plane.Type: GrantFiled: October 26, 2005Date of Patent: June 6, 2006Assignee: JDS Uniphase CorporationInventors: Michael Francis Hanley, James Robert Moon, Bruce P. Kruger, David Peter Gaio

Patent number: 6935882Abstract: The invention relates to a latch device for a pluggable opto-electronic module, such as an optical transceiver, for locking the module in a rail or cage system of a host machine. The latest generation of optical transceivers include all metal housings, instead of all plastic or partial plastic, to ensure adequate heat dissipation. The relatively heavier housings necessitate the use of more robust latch devices. The latch device according to the present invention includes a sliding element with arms extending therefrom for pivoting a latching hook out of engagement with the rail or cage system. In a preferred embodiment, a pair of latching hooks are provided, one on each side of the module. The latching hooks are mounted on the ends of spring arms, which extend from the same sheet of spring metal positioned across the bottom of the housing.Type: GrantFiled: June 2, 2003Date of Patent: August 30, 2005Assignee: JDS Uniphase CorporationInventors: Michael Francis Hanley, Gerald Daniel Malagrino Jr.
