SFP tranceiver / Singlemode SFP Transceiver
The SFP transceiver supports dual data-rate of 1.25Gbps/1.0625Gbps and from 10km to 20km transmission distance with SMF or 550m with MMF.
The transceiver consists of two sections: The transmitter section incorporates a FP laser. The receiver section consists of a PIN photodiode integrated with a trans-impedance preamplier (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 indicates that degradation of the laser. Loss of signal (LOS) output indicates 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 bus. For more information, please refer to SFP Multi-Source Agreement (MSA)

    Notes :
    1 TX Fault is an open collector/drain output, which should be pulled up with a
    4.7K -10K resistor on the host board. Pull up voltage between 2.0V and VccT, R+0.3V.
    When high, output indicates a laser fault of some kind. Low indicates normal
    operation.
    In the low state, the output will be pulled to < 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
    (>0.8V~<2.0V): Undened
    High (2.0~3.465V): Transmitter Disabled
    Open: Transmitter Disabled
    3 MOD-DEF 0,1,2 are the module denition 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 dierential receiver output. They are internally AC-coupled 100 dierential lines which should be terminated with 100 (dierential) at the user SERDES.
    6 These are the dierential transmitter inputs. They are AC-coupled, dierential lines with 100 dierential termination inside the module.
