Description
FTM-5012C-SL80G SFP transceiver is high performance, cost effective module supporting data-rate of 1.25Gbps and 80km transmission distance on SMF.
Features
Data-rate of 1.25Gbps operation 80km transmission with SMF 1550nm DFB laser and PIN photo-detector SFP MSA package with duplex LC connector With Spring-Latch for high density application Very low EMI and excellent ESD protection +3.3V single power supply Operating case temperature: 0~+70C
The transceiver consists of two sections: The transmitter section incorporates a DFB laser. And the receiver section consists of a PIN photodiode integrated with a trans-impedance preamplifier (TIA). All modules satisfy class I laser safety requirements. 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 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). FTM-5012C-SL80G is compliant with RoHS.

1. TX Fault is an open collector output, which should be pulled up with a 4.7k~10k 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~10k resistor. Its states are: Low (0~0.8V): Transmitter on

3. MOD-DEF 0,1,2 are the module definition PINs. They should be pulled up with a 4.7k~10k resistor on the host board. The pull-up voltage shall be VccT or VccR. MOD-DEF 0 is grounded by the module to indicate that the module is present MOD-DEF 1 is the clock line of two wire serial interface for serial ID MOD-DEF 2 is the data line of two wire serial interface for serial ID 4. LOS is an open collector output, which should be pulled up with a 4.7k~10k resistor on the host board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates loss of signal. In the low state, the output will be pulled to less than 0.8V. 5. These are the differential receiver output. They are internally AC-coupled 100 differential lines which should be terminated with 100 (differential) at the user SERDES.
6. These are the differential transmitter inputs. They are AC-coupled, differential lines with 100 differential termination inside the module.
