Note : 1. The module signal ground contacts, VeeR and VeeT, should be isolated from the module case.
2. The TTL level TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩresistor on the host
board to VccT. When high, output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the
output will be pulled to < 0.8V. When sensing an improper power level in the laser driver, the SFP sets this signal high and
turns off the laser. TX-FAULT can be reset with the TX-DISABLE line.
3. TX disable is an input that is used to shut down the transmitter optical output. It is pulled up within the modulewith a
4.7 – 10 KΩ resistor. The states are: Low (0 – 0.8V): Transmitter on / (>0.8, < 2.0V): Undefined / High (>2.0): Transmitter
Disabled / Open:Transmitter Disabled. Make TX-DISABLE high (TTL logic “1”) to turn off the laser output. The laser will turn
on when TX-DISABLE is low (TTL logic “0”).
4. These are the module definition pins. They should be pulled up with a 4.7K – 10KΩ resistor on the host boardto supply
less than VccT+0.3V or VccR+0.3V.
5. Not used.

Note : 1. GND is the symbol for signal and supply (power) common for the QSFP module. All are common within the QSFP module
and all module voltages are referenced to this potential unless otherwise noted. Connect these directly to the host board signal
-common ground plane.
2. Vcc Rx, Vcc1 and Vcc Tx are the receiver and transmitter power supplies and shall be applied concurrently. Vcc Rx, Vcc1 and
Vcc Tx may be internally connected within the QSFP transceiver module in anycombination. The connector pins are each rated
for a maximum current of 500 mA.
3. Not used.
