Notes:
[1] The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level
[2] Average receive power (min) is informative and not the principal indicator of signal strength. A received power below this value cannot be compliant; however, a value above this does not ensure compliance.
[3] Receiver sensitivity (OMAouter) (max) is informative and is defined for a transmitter with a value of SECQ up to 3.2 dB for 50GBASE-ER. The value of BER is 2e-4(before FEC).
[4] Measured with conformance test signal at TP3 (see 139.7.10) for the BER specified in 139.1.1 (IEEE802.3cd)
[5] These test conditions are for measuring stressed receiver sensitivity. They are not characteristics of the receiver

Notes:
[1] Time from power on, hot plug or rising edgeof reset until the module is fullyfunctional. This time does not apply tonon-Power level 0 modules in Low Power State.
[2] A Reset is generated by a low level longerthan t_reset_init present on the ResetLinput.
[3] Time from power on until the moduleresponds to data transmission over the twowireserial bus.
[4] Time from assertion of LPMode (Vin:LPMode =Vih) until module power consumption reachesPower Level 1.
[5] Time from deassertion of LPMode (Vin:LPMode =Vil) until module is fully functional,
[6]Time from occurrence of condition triggeringIntL until Vout:IntL=Vol.
[7] Time from clear on read operation ofassociated flag until Vout:IntL=Voh. Thisincludes deassert times for Rx LOS, Tx Faultand other flag bits.
[8]Time from Rx LOS state to Rx LOS bit set(value = 1b) and IntL asserted.
[9]Time from Tx Fault state to Tx Fault bit set(value = 1b) and IntL asserted.

[11]Time from mask bit set (value = 1b) untilassociated IntL assertion is inhibited.
[12]Time from mask bit cleared (value = 0b)until associated IntL operation resumes.
[13]Time from change of state of Application orRate Select bit until transmitter orreceiver bandwidth is in conformance withappropriate specification.
[14]Time from P_Down bit set (value = 1b) untilmodule power consumption reaches Power Level1

Notes:
[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 VccTx are the receiver and transmitter power supplies and shall be applied concurrently. Recommended host board power supply filtering is shown in Figure 7. Vcc Rx Vcc1 and VccTx may be internally connected within the QSFP+ Module in any combination. The connector pins are each rated for a maximum current of 500 mA.
[3] NC is Not Connect.
Block Diagram of Transceiver
Recommended Interface Circuit
The host board should use the power supply filtering equivalent to that shown in Figure4. Any voltage drop across a filter network on the host is counted against the host DC set point accuracy specification. Inductors with DC resistance of less than 0.1 Ohm should be used in order to maintain the required voltage at the Host Edge Card Connector. It is recommended that the 22 uF capacitors each have an equivalent series resistance of 0.22 ohm.
Mechanical Dimensions
Unit is millimeter.
