It is designed for 100BASE-FX applications from 0.5m to 2km with MMF. The transceiver consists of two sections: The standard SFP part and the PHY part. FTM-8401C-SL2CG is built with SGMII interface. The optical output can be disabled by a TTL logic high-level input of Tx Disable. Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver. The standard serial ID information Compatible with SFP MSA describes the transceiver’s capabilities, standard interfaces, manufacturer and other information. The host equipment can access this information via the 2-wire serial CMOS EEPROM protocol. For further information, please refer to SFP Multi-Source Agreement (MSA).

Easier Configuration Designing-in a high performance MCU in FTM-8401C-SL2CG, host can configure Fiberxon’s SGMII series product easily. For FTM-8401C-SL2CG, host only need access few registers of A0H via I2C to configure SGMII series module, such as speed-selection, Auto-negotiation, LOS/Link detection, TX disable, FEFI/RFI and CRC counter function support. Host can get inner status via access specific register of FTM-8401C-SL2CG. The operation data rate can be configured via hardware pin and I2C bus independently. For more detailed information, please refer to application note of FTM-8401C-SL2CG. Recommended Host Board Power Supply Circuit Figure 1 shows the recommended host board power supply circuit.

TX Fault is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor on the host board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates a laser fault of some kind. In the low state, the output will be pulled to less than 0.8V. 2. TX Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a 4.7k~10kΩ resistor. Its states are: Low (0~0.8V): (>0.8V,
