The SPFEIM100_G is a high-speed fiber optic transceiver for converting high-speed binary data to differential digital data. It supports Fast Ethernet with a data rate of up to 100Mbit/s (125MBaud). It features integrated EMI shielding, operates at a temperature range of 0°C to 70°C, and uses a 3.3V power supply. It supports thin and flexible Plastic Optical Fiber (POF) with a 1.5mm outer jacket diameter and has a fiber pull-out strength of over 20N at 25°C. The transceiver uses a 650nm LED with an integrated driving circuit and does not toggle the LED when there are no signals on the input data lines.
The SMFEIM100_G is an 8‑pin optical transceiver that integrates a CMOS IC with a high‑speed photodiode and LED to transmit and receive up to 125 Mbit/s optical data for Fast Ethernet over plastic optical fiber (POF). It is designed for operation at 3.3 V and includes integrated EMI shielding and a green, lead‑free package.
Key specifications include a data rate of up to 125 Mbps, operating temperature range of 0 °C to 70 °C, supply voltage of 3.05‑3.55 V, and a peak LED wavelength of 650 nm. The device supports a maximum transmission length of 50 m on POF and provides detailed electrical and optical characteristics for both transmitter and receiver sections.
