The SFP transceivers are high performance, cost effective modules supporting data-rate of 155Mbps and 80km
transmission distance with SMF.
The transceiver consists of three sections: an uncooled CWDM DFB laser transmitter, a PIN photodiode integrated with
a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.

The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information,
please refer to SFP MSA.

Plug Seq.: Pin engagement sequence during hot plugging.
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 andVcc+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 to 0.8V):             Transmitter on
(>0.8V, < 2.0V):             Undefined
High (2.0 to 3.465V):         Transmitter Disabled
Open:                      Transmitter Disabled
3) Mod-Def 0,1,2. These 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. Pull up voltage
between 2.0V and Vcc+0.3V.
Logic 1 indicates loss of signal; Logic 0 indicates normal operation. In the low state, the output will be
pulled to less than 0.8V.
5) RD-/+: These are the differential receiver outputs. They are internally AC-coupled 100 differential lines
which should be terminated with
100Ω (differential) at the user SERDES.
6) TD-/+: These are the differential transmitter inputs. They are internally AC-coupled, differential lines
with 100Ω differential termination inside the module.
