Description
This module provides long-distance and interference-free fiber-optic communication with a baud rate of 2,000,000 and a maximum range of 10km. It has complete electrical isolation to prevent electromagnetic interference and is equipped with lightning protection and the ability to share cable trunking with strong power. You can also use it with a passive optical splitter to create a one-to-many star network.
At just half the price of shielded twisted pair, this module provides users with an affordable solution for long-distance and interference-free communication.
