And even drop the baud rate again and again just for transmission stability? Now get rid of these problems by using this Gravity: UART Fiber Optic Transceiver Module from DFRobot! With complete electrical isolation for preventing electromagnetic interference, this module runs at 2000000 baud at any time within a distance of up to 10km. Besides, it features lightning protection and can share cable trunking with strong power. Also, users can use it with a passive optical splitter to realize one-to-many star networking. Two transceiver modules for only half the price of shielded twisted pair can provide users with long-distance & interference-free fiber-optic communication, good value for money!Interface & PinPinout\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tName\t\t\t\t\t\t\t\t\t\t\t\t\tDescription\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tGravity: UART\t\t\t\t\t\t\t\t\t\t\t\t\tUART interface, connect to MCU or sensor\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tPWR LED\t\t\t\t\t\t\t\t\t\t\t\t\tPower indicator, turns ON when powered on\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tSD LED\t\t\t\t\t\t\t\t\t\t\t\t\tIndicator for optical fiber disconnection, which lights up when the fiber optic disconnection is detected\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tTX LED\t\t\t\t\t\t\t\t\t\t\t\t\tIndicator for fiber optic transmitting, which blinks when transmitting signal\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tRX LED\t\t\t\t\t\t\t\t\t\t\t\t\tIndicator for fiber optic receiving, which blinks when receiving signal\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tSC Fiber Optic Interface\t\t\t\t\t\t\t\t\t\t\t\t\tConnect to SC fiber optic interface\t\t\t\t\t\t\t\t\t\t\t\tSD LED can not show all the fiber disconnections or unstable transmissions.
