Abstract:
1. An optical module comprising: a fiber array including plural optical fibers which are divided to at least a transmitter group and a receiver group; a laser diode array including plural laser diodes which are grouped in at least a transmitter group; a photodiode array including plural photodiodes which are divided to at least a monitor group and a receiver group, the laser diode array being provided between the fiber array and the photodiode array such that each of end surfaces of the plural optical fibers of the transmitter group faces each of the plural laser diodes of the transmitter group, each of the plural optical fibers of the transmitter group, each of the plural laser diodes of the transmitter group and each of the plural photodiodes of the monitor group being optically aligned, respectively, and each of the plural optical fibers of the receiver group being optically aligned with each of the plural photodiodes of the receiver group, respectively; and a mechanical transfer ferrule having plural optical fibers which are divided to at least a transmitter group and a receiver group and which are provided between the laser diode array and the photodiode array, each of the plural optical fibers of the transmitter group of the fiber array, each of the plural laser diodes of the transmitter group, each of the plural optical fibers of the transmitter group of the mechanical transfer ferrule and each of the plural photodiodes of the monitor group being optically aligned along an optical axis direction of transmitter groups, respectively, and each of the plural optical fibers of the receiver group of the fiber array, each of the plural optical fibers of the receiver group of the mechanical transfer ferrule and each of the plural photodiodes of the receiver group being optically aligned along an optical axis direction of receiver groups, respectively.
