a) RSSI_ACQ input signal rising edge will trigger RSSI sampling, and falling edge will trigger internal digital RSSI information written to I2C. It is recommended that host shall not trigger RSSI_ACQ input again until RSSI data is valid inI2C from previous RSSI trigger. b) RSSI DDM working range is between -8 to -28dBm. RSSI DDM accuracy is better than +/-3dB for input power level between -10 to -28dBm, the accuracy reduces to +/-5dBm to -10 dBm. If the data pattern is at least 2^7-1 or longer, a minimum average of 8 times is strongly recommended to maintain the RSSI reading accuracy.

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 isthe clock line of two wire serial interface for serial ID. MOD-DEF 2 isthe 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 outputs. They are AC coupled 100Ω differential lines which should be terminated with 100Ω (differential) atthe user SERDES.6. These are the differential transmitter inputs.

Receiver Power DDM(RSSI) Error	–	–	+/-3	dB	–
a) RSSI_ACQ input signal rising edge will trigger RSSI sampling, and falling edge will trigger internal digital RSSI information written to I2C. It is recommended that host shall not trigger RSSI_ACQ input again until RSSI data is valid inI2C from previous RSSI trigger. b) RSSI DDM working range is between -8 to -28dBm. RSSI DDM accuracy is better than +/-3dB for input power level between -10 to -28dBm, the accuracy reduces to +/-5dBm to -10 dBm. If the data pattern is at least 2^7-1 or longer, a minimum average of 8 times is strongly recommended to maintain the RSSI reading accuracy.

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 isthe clock line of two wire serial interface for serial ID. MOD-DEF 2 isthe 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 outputs. They are AC coupled 100Ω differential lines which should be terminated with 100Ω (differential) atthe user SERDES.6. These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential termination inside the module.

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 isthe clock line of two wire serial interface for serial ID. MOD-DEF 2 isthe 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 outputs. They are AC coupled 100Ω differential lines which should be terminated with 100Ω (differential) atthe user SERDES. 6. These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential termination inside the module.

PRODUCT PRESENTATION

The PHILISUN EPON OLT PX20+ 3dBm Transceiver is a bidirectional 1.25G SFP module designed for OLT equipment, operating at 1490nm downstream / 1310nm upstream wavelengths over single-mode fiber (SMF) for distances up to 20km. Featuring an SC connector interface and compliant with the PX20+ class with a 3dBm optical budget, it provides differential 100 Ohm termination for both transmitter input and receiver output data lines. Internal AC coupling ensures quality signal termination, while its design minimizes differential-to-common mode conversion for enhanced signal integrity and reduced EMI.
