Description:
The 155M SFP transceiver supports dual data-rate of 155MGbps and from 10km to 20km transmission distance with SMF
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 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 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 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): Transmitter on
(>0.8V, <2.0V): Undefined
High (2.0~3.465V): Transmitter Disabled
Open: Transmitter Disabled
3. MOD-DEF 0,1,2 are the module definition pins. They should be pulled up with a 4.7k~10kΩ 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~10kΩ 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 100Ω differential lines which should be terminated with 100Ω (differential) at the user SERDES.
6. These are the differential transmitter inputs. T
