The FI4I002LC is a cable-integrated fiber-optic transmitter and receiver module designed to extend the transmission distance of industrial Ethernet and fieldbus systems. It is designed for Ethernet or fieldbus applications that require distances longer than 100 m (328 ft) for point-to-point connections. It provides a cost-effective solution for environments where long distance transmission of Ethernet or fieldbus signals is necessary.

The FI4I002LC features low power consumption, advanced diagnostic functions and network protection. It also provides superior transmission performance, high EMI/RFI immunity and advanced features, such as data auto-sensing, link monitoring and cyclic redundancy check (CRC).

This type of module is mainly used in industrial automation, telecommunications, railway, security, defense, and energy markets. It is ideal for applications requiring extension of remotely controlled devices from a central station and/or use of high-speed industrial Ethernet or fieldbus systems.

The FI4I002LC consists of a transmitter and a receiver connected by a single fiber-optic cable, with optical connectors at the ends of the cable. The device is designed to support high-speed differential signaling over twisted-pair cables. It supports 1, 10, and 100 Mbps data rates.

The transmitter is an opto-electronic circuit, which converts electrical signals into optical signals for transmission down the optical fiber. The receiver turns the optical signals back into electrical signals for transmission on the twisted pair ppper cable. The transmitter requires a signal level of at least 700 mV to be present to start the process. The transmitter is capable of accepting signals up to 30 V.

The receiver converts the optical signal back into an electrical signal and then passes it to the twisted pair copper cable. This optical signal is converted using a process called photodetection. The receiver uses a directional coupler to combine light from the optical fiber with an optical reference signal that is used to adjust its sensitivity level.

The FI4I002LC is a cost-effective solution for extending transmission distance of twisted-pair cables over long distances. It is ideal for applications requiring longer distances than 100 m (328 ft), such as industrial Ethernet and fieldbus systems. It features low power consumption, advanced diagnostic functions, high EMI/RFI immunity, and other features, such as data auto-sensing, link monitoring, and CRC.
