With the development of optical fiber communication technology, the comprehensive wiring of optical fiber cables has been widely used in data communication and exchange occasions. However, the traditional optical fiber cable integrated wiring pre-termination system cannot realize corresponding input and output of optical signals on ports at the same position, so that the wiring engineering design is complicated and the operation and maintenance are difficult, especially the wiring modes of two branch modules are different, and errors are easy to occur in the construction process, so that equipment such as an integrated wiring switch and a server cannot be connected. It is desirable to provide a generic fiber optic drop module scheme that enables the reversal of common polarity.
