The digital value conversions are updated every 13ms (nominal) or 20ms (max) in rotation. After getting digital value,
each measurement could be obtained by multiplying digital value by corresponding LSB value:
1
Temperature = Temp (Digital Value)  LSBTemp = Temp (Digital Value)  256; when Temperature<128

Temperature = Temp (Digital Value)  LSBTemp = [Temp (Digital Value)  256]-256; when Temperature≧128

Notes:
1) Circuit ground is internally isolated from frame (chassis) ground. Tx GND and Rx GND may be
internally isolated within the TRx module.
2) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K~10KΩ resistor on
the host board. Pull up voltage between 2.0V and VccT+0.3V. The output indicates Low when the
transmitter is operating normally, and High with a laser fault including laser end-of-life. In the low state,
the output will be pulled to less than 0.8V.

down resistor within the module. Its states are:
Low (0 – 0.8V):
Transmitter on
(>0.8, < 2.0V):
Undefined
High (2.0 – 3.465V): Transmitter Disable
Open:
Transmitter Disable
MOD-ABS: Mod_ABS is connected to VeeT or VeeR in the SFP+ module. The host may pull this
contact up to Vcc_Host with a resistor in the range 4.7 k ohm to10 k ohm. Mod_ABS is asserted
“High” when the SFP+ module is physically absent from a host slot.
RD-/+ : These are the differential receiver outputs. They are AC-coupled, CML compatible interface
required 100ohm differential load on the host board.
VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5% at the
SFP connector pin. Recommended host board power supply filtering is shown as below. Inductors
with DC resistance of less than 1 Ohm should be used in order to maintain the required voltage at the
SFP input pin with 3.3V supply voltage. When the recommended supply-filtering network is used, hot
plugging of the SFP transceiver module will result in an inrush current of no more than 30 mA greater
than the steady state value.
TD-/+: These are the differential transmitter inputs. They are AC coupled, differential lines with 100Ω
differential termination inside the module.
