Note:
1. Even if the TDP<1dB,the OMA min must exceed the minimum value specified here.
2. The receiver shall be able to tolerate, without damage, continuous exposure to a modulated optical input signal having this power level on one lane. The receiver does not have to operate correctly at this input power.
3. Sensitivity is specified at 5×10^-5 BER at 25.78125Gb/s.

Note:
1.GND is the symbol for single and supply(power) common for QSFP modules, All are common within the QSFP module and all module voltages are referenced to this potential otherwise noted. Connect these directly to the host board signal common ground plane. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.
2.VccRx, Vcc1 and VccTx are the receiver and transmitter power suppliers and shall be applied concurrently. Recommended host board power supply filtering is shown below. VccRx, Vcc1 and VccTx may be internally connected within the QSFP transceiver module in any combination. The connector pins are each rated for maximum current of 500mA.
8 Optical Interface Lanes and Assignment
The optical interface port is a male MPO connector. The four fiber positions on the left as shown in Figure 2,
with the key up, are used for the optical transmit signals (Channel 1 through4).
The fiber positions on the right are used for the optical receive signals (Channel 4 through 1).
The central four fibers are physically present.
