  • Optical module TX and RX connected in reverse

    Optical module TX and RX connected in reverse

    A fiber-optic link can function only if Tx on one end is connected to Rx on the other, and vice versa; this is accomplished by creating a fiber polarity flip that swaps Tx for Rx at some point in the link. For duplex transmission, this is relatively straightforward to accomplish. In fiber optics, data travels from the Tx port of one device to the Rx port of another, forming a two-way communication path. If you do not maintain polarity — by connecting Tx to Tx, for example — data flow stops. 3-E standard recommends an A-B polarity scenario for duplex. In any installation, it is important to ensure that the optical transmitter at one end is connected to the optical receiver at the other.
