Array is a device made up of bundled small-diameter optical fibers, and is used as a signal transmitter in communication and network systems. In the past, for the installation of new network cables, due to the high labor cost and the long construction period, the use of arrays has been greatly reduced.Since the development of the new optical fiber array system, the construction period has been greatly reduced, and the cost has also been reduced.

Array consists of optical fiber coupler and optical fiber cable, and can realize the output of multi-channel optical signals from one signal source. The advantage of the array is that the cable layout becomes more flexible and the device becomes smaller. Besides, the power distribution of the signal can be adjusted by means of the connection method of the optical fiber coupler. Thus, it is widely used in network communication system.

The working principle of the array is simple. When transmitting multiple optical signals through an optical fiber array, the optical signal of the channel needs to pass the multiplexer connected at the exit port in the front-end. When the multiplexer receives these optical signals, it divides them into different frequency bands and selects different paths at the output. Then, the multiplexer compresses the optical signal of different frequencies into multiple channels and transmits it out through the many output ports of the multiplexer. On the receiving end, the multiplexer at the back end will classify the signal into different frequency bands, and then output them at different ports.
