QUAD SMALL FORM FACTOR PLUGGABLE (QSFP) ADAPTER MODULE

摘要

Fiber adapter modules for use as interfaces at both ends of multi- fiber trunk cables position the channels of plural fiber optic transceivers onto fibers of the trunk cables in an efficient manner, such that normally dark fibers of a trunk cables are utilized. The fiber adapter modules include trunk- side ports for receiving adapters of multi -fiber trunk cables having at least 12fibres of the adapter and transceiver- side ports for receiving adapters carrying both transmit channels and receive channels of fiber optic transceivers and using only 8 from the at least 12 fibres. Optical interconnections are provided within the fiber adapter modules to place at least one transmit channel or at least one receive channel of a first fiber optic transceiver at a first trunk- side port and to place at least one transmit channel or at least one receive channel of a second fiber optic transceiver at the first trunk- side port.
