In fiber media converter, TX stands for Transmit and RX stands for Receive. Fiber polarity is the direction that light signals travel from one end of a fiber optic cable (link) to the other. Although it may seem obvious, fiber optic polarity is a frequent source of confusion and. Polarity in fiber optic networks refers to the alignment of transmit (Tx) and receive (Rx) signals between interconnected devices. They refer to how data moves in a network. The transmitter (TX) is responsible for converting electrical signals into optical signals, which are then transmitted. A fundamental concept in understanding how media converters operate revolves around the terms TX and RX. If it's too strong, the camera gets blinded.
