Still make do with the hard and thick shielded twisted pair for remote signal-transmitting? 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!
