The invention discloses a multi-channel
optical module based on double LC interfaces, and belongs to the technical field of optical modules. The
optical module comprises an LD module with N channels, a multi-
core optical fiber fan-in device with N input ports, a multi-
core optical fiber which is coupled with the output port of the multi-
core optical fiber fan-in device and is provided with N cores, and a multi-core
optical fiber LC connector which is connected with the multi-core
optical fiber, which are sequentially arranged along the direction of an output
optical axis; the other multi-core
optical fiber LC connector, the other N-core multi-core optical
fiber connected with the other multi-core optical
fiber LC connector, the multi-core optical
fiber fan-out device coupled with the other N-core multi-core optical fiber and provided with N output ports, and a
detector array connected with the N output ports of the multi-core optical fiber fan-out device, which are sequentially arranged in the direction of the input
optical axis. According to the invention, the transmission of the
optical module with 2N transceiving channels can be realized by using two multi-core optical fibers with N cores, so that the overall cost is better while the wiring space is saved.
