Patent ID: 8406587

Claim:
A fiber adapter module comprising: a trunk-side port for receiving a connector plug of a multi-fiber trunk cable; a plurality of transceiver-side ports for receiving connector plugs carrying both transmit channels and receive channels for at least a first fiber optic transceiver and a second fiber optic transceiver; and optical interconnections within said fiber adapter module to place at least one transmit channel or at least one receive channel of the first fiber optic transceiver at said trunk-side port and to place at least one transmit channel or at least one receive channel of the second fiber optic transceiver at said trunk-side port, wherein said trunk-side port is a first trunk-side port formed by a twelve fiber MPO receptacle, said fiber adapter module further comprising: a second trunk-side port for receiving a connector plug of a multi-fiber trunk cable, wherein said second trunk-side port is formed by a twelve fiber MPO receptacle; and wherein said plurality of transceiver-side ports includes: a first twelve fiber MPO transceiver-side port for passing four transmit channels and four receive channels of the first fiber optic transceiver to said optical interconnections; a second twelve fiber MPO transceiver-side port for passing four transmit channels and four receive channels of the second fiber optic transceiver to said optical interconnections; and a third twelve fiber MPO transceiver-side port for passing four transmit channels and four receive channels of a third fiber optic transceiver to said optical interconnections.
