Description
The SFP transceivers are high performance, cost effective modules supporting
data-rate of 2.67Gbps and 300m transmission distance with MMF.
The transceiver consists of three sections: a VCSEL 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.

1) TD+/- are internally AC coupled with 100Ω differential termination inside
the module.
Note
2) Tx Fault and Rx LOS are open collector outputs, which should be pulled up
with 4.7k to 10kΩ resistors on the host board. Pull up voltage between 2.0V and

Note 1) When high, this output indicates a laser
fault of some kind. Low indicates normal operation. And should be pulled up
with a 4.7 – 10KΩ resistor on the host board.
Note 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 4.7 – 10KΩ resistor. Its states are:
Low (0 –
0.8V): Transmitter on
(>0.8, < 2.0V): Undefined
High
(2.0V~Vcc+0.3V): Transmitter Disabled
Open: Transmitter Disabled
Note 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 between 2.0V~Vcc+0.3V.
Mod-Def 0 has been 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
Note 4) When high, this output indicates loss of
signal (LOS). Low indicates normal operation.
Note 5) RD+/-: These are the differential receiver
outputs. They are AC coupled 100Ω differential lines which should be terminated
with 100Ω (differential) at the user SERDES. The AC coupling is done inside the
module and is thus not required on the host board.
Note 6) TD+/-: These are the
differential transmitter inputs. They are AC-coupled, differential lines with
100Ω differential termination inside the module. The AC coupling is done inside
the module and is thus not required on the host board.
