Abstract
Abstract In a circuit card assembly for use within an information processor (computer) wherein the assembly includes a fiber optic connector assembly as part thereof, there is provided means for enabling electrical connections to be made to the circuit card's circuitry in the same area as the fiber optic connector's housing so that charging of the card (to the potential of the mother board to which it will be coupled) can occur prior to coupling of the card to the board. Once the card is positioned and thus connected to the board, the charging means of the invention can be removed and a desired fiber optic connector inserted within the housing so that desired optical connections can be made with corresponding components (e.g., receiver, transmitter) which form part of the circuit card assembly. Both optical and electrical connections thus occur within the same housing.
